He is a "historical witness" of China's earth-shaking changes for half a century, and a "national builder" who devoted his lifelong efforts and wisdom on the journey of China's rise; he is also an internationally recognized "sword holder" in the field of fluidization and reaction engineering, and a "pioneer" in the development and practice of related disciplines in the field of circular economy; he is also a spokesperson for "beautiful chemicals" who is still fighting on the front line of popular science education in chemical and chemical engineering in his 80s. He is a famous chemical engineering expert in my country and an academician of the Chinese Academy of Engineering - Jinyong .
Fixed Bed
Zhijian International Reaction Engineering Research on the Fixed Bed Reaction Engineering of Joint
is an accidental encounter for Jin Yong. After returning to China after studying in the Soviet Union in 1959, Jin Yong was first assigned to teach at University of Science and Technology of China. Until 1973, since the University of Science and Technology of China no longer established a radiochemistry major, Jin Yong came to Tsinghua University to continue teaching and research work. He also took 18 students to Beijing Chemical Factory No. 2 to "open the school" with the same group of teachers.
At that time, a large fluidized bed reactor imported by the Soviet Union was unable to produce normally and stably due to long-term operation damage. The factory held a concentrated discussion on how to transform the equipment, and Jinyong's education and reform team was also invited to participate. This is undoubtedly a huge challenge. Without engineering experience in designing fluidized beds, Jin Yong took teachers and students to inquire about the latest academic progress in international fluidized engineering with solid basic knowledge. For some key component sizes that were not accurate, they also specially borrowed experimental equipment test data and test verification at that time. With the enthusiastic support and help of technicians and operators in the workshop factory, the task was successfully completed. Jin Yong recalled: "When the equipment was put into operation, a suspended heart fell down. Not only did the advanced technology used in the equipment run normally, but most of the technical indicators also exceeded the original Soviet equipment."
In 1979, Jin Yong led the establishment of the Reaction Engineering Research Office of Tsinghua University (FLOTU). The laboratory has established a high international reputation in basic research and industrial applications of multiphase reactors, especially fluidized bed reactors, and laid the foundation for the current "Beijing Key Laboratory of Green Reaction Engineering and Technology" and the "Engineering Research Center of the Ministry of Education of Clean Energy and Chemical Technology".
Under the leadership of Jinyong, Tsinghua University's Reaction Engineering Research Office has achieved three studies in the world's leading position and has achieved outstanding application results in production, namely gas-solid fluidization flow transformation and engineering development, gas-solid concurrent flow downstream reactor research and development, and agglomerated fluidization basic and application research.
How to control the transformation from bubble flow to turbulence in fluidization reactors with different reaction conditions is the first major research topic in the research office at the beginning of its establishment. Together with the graduate students, Jin Yong and the graduate students built corresponding reaction systems based on multiple influencing factors such as different temperatures, pressures, fluid phase viscosity, surface tension, heavyness, particle size, particle size distribution and two-phase particle speed, and proposed a criterion for judging the operating state and flow transformation of the gas-solid two-phase fluidized bed reactor. Later, they used this as a guide to transform chemical reactors on the front line of production. From the 1990s to the present, based on this research result, the research team has transformed large industrial reactors with nearly 10 different processes and designed more than 30 new reactor devices, which has improved the reaction conversion rate, selectivity and equipment production capacity, making this reactor a standard equipment in specific fields of the chemical industry. With research on flow transformation of fluidized reactors, Jin Yong and he led the research team to win the second prize of the National Invention and the second prize of the National Science Progress Award in 1987 and 1996, as well as more than 10 ministerial science and technology progress awards including the Ministry of Education, China Petroleum and Chemical Industry Corporation, China Petroleum and Chemical Industry Federation, etc.
Shortly after, the laboratory began to research the transformation of the catalytic cracking lift pipe reactor from the upstream of the parallel flow to the downstream of the gas-solid parallel flow. Jin Yong quickly focused his research on the direction of solid qi flowing downward. It was the first in the world to fully understand the special laws of the movement of the two phases of Qi-solid according to the gravity field, and became the leader in research in this field.With the support of Jinan Oil Refinery, the research team changed an upward lifting pipe into a downward reactor, fully demonstrating its superiority and improving the yield and selective efficiency of the catalytic pipe reaction. It is precisely because of their persistence that our country's basic research in this field has always been at the leading international position.
Against the backdrop of the rise of nanoscience around the world, Jinhong extends the application range of traditional fluidization technology to the size of particles to smaller nanosizes. From the micro-scale restricted area that is recognized as "unable to fluidization" to the nanoscale, they studied the basic behavior of fluidization of nanoparticles agglomeration and conducted industrial application research, which is the first in the world.
Based on outstanding contributions to the above research fields, the Jinyong Research Team won the PSRI fluidization lecture award awarded by the American Institute of Chemical Engineers (AICHE) in 2006.
After more than 40 years, the research room has worked together by generations of teachers and students. The gas-solid turbulent fluidized beds, gas-solid circulating fluidized beds, gas-solid ultra-short contact catalytic reactors, gas-liquid-solid three-phase fluidized beds, mobile bed reforming reactors, nanomaterial preparation agglomerated fluidized bed reactors, large-scale energy-saving drying devices, etc. have been successfully applied to production. In more than a dozen different production processes, dozens of large chemical reactors have been designed, achieving significant economic and social benefits.
Advocate circular economy
Become a pioneer in ecological civilization
Entering the new century, Jin Yong withdrew from the front line of fluidized bed reactor research, began to put his vision on the general direction of the entire industrial economy and environmental protection, and introduced the new scientific concept of circular economy into our country.
The industrial revolution officially announced that mankind has entered the era of great industrial development, but the industrial society is about efficiency and development, constantly exploitation and production, and after large-scale use, it discarded in large quantities, and established a linear economic development model to the extreme, resulting in continuous depletion of resources and continuous pollution of the environment. The industrial era runs contrary to the laws of natural ecological development. At the end of the last century, mankind gradually realized the importance of respecting the laws of natural development. Germany, Japan and other countries were the first to list the circular economy as a key development for planning. After Jinyong and other experts and scholars in my country introduced this concept into our country for brewing and fermenting. In 2002, Jinyong invited more than 40 academicians and experts to apply for the topic of "Ecological Industrial Engineering and Ecological Industrial Park Construction" at the 198th Xiangshan Conference. It was also at this conference that the scholars present proposed to the Chinese people the concept of ecological economy , the predecessor of circular economy, for the first time. The results of this Xiangshan Science Conference were significant: they unified their understanding in the academic community and clarified the definition, connotation, guiding ideology and development direction of ecological economy. After
, they took the lead in establishing the Ecological Industrial Engineering and Circular Economy Association, visited and supported the pilot projects of the Ministry of Environmental Protection and the National Development and Reform Commission to promote the development of circular economy and the planning and construction of enterprise ecological industrial parks. The association holds an academic annual meeting every year to discuss the newly established "Resource Circulation Science and Engineering" courses of the Ministry of Education, and conducts relevant talent training work, making important contributions to the development of my country's circular economy.
Jinyong participated in the entire process of circular economy from concept to project implementation in China, and explained and promoted the strategic significance and development concept of circular economy development to provincial and municipal government officials and entrepreneurs, so that the whole society reached a consensus on the circular economy development strategy: the circular economy is in line with the current development status of my country and is an effective means for my country to transform its development model and achieve sustainable development. With the advent of the circular economy concept and the implementation of relevant policies and measures, GDP, once the only criterion for measuring economic development across the country and in various regions, is no longer the only baton.
During this period, he wrote monographs such as "Ecological Industry: Principles and Applications" and "Resources, Energy, Environment, Society", becoming one of the pioneers in my country's advocacy of circular economy and ecological civilization.

Love the popular science of chemical engineering
Incarnate as the spokesperson of "Beautiful Chemical Engineering"
0 Since becoming acquainted with chemical engineering in his youth, Jin Yong has been proud of his life's research in chemical engineering.However, misled by various wrong ideas in recent years, chemical industry has been demonized and has been detained as an "notorious" of uneco-friendly, unsafe and unhealthy. As an old scientist in the field of chemical engineering, Jin Yong deeply feels that he has an obligation to promote chemical knowledge to the public.
"In recent years, many negative information has demonized the chemical industry, and the people have become prejudiced against chemical industry. Parents and students are afraid of learning chemical industry. As a basic major that concerns the national economy and people's livelihood, they have been cold in the training of professional talents. If this problem cannot be solved in time, it will have an immeasurable negative impact on my country's chemical engineering discipline education and the progress of the chemical industry." Jin Yong said, "In fact, the economic development of modern society and the food, clothing, housing and transportation of human beings are inseparable from chemical and chemical products. The synthetic fiber produced in my country every year can make 4 sets of clothes for everyone in the world; the agricultural chemicals produced increase the grain output from 100 million tons at the beginning of the founding of the People's Republic of China. The current 650 million tons of gasoline, diesel, batteries, rubber, etc. required for automobile production and use also come from the general chemical industry. The chemical industry also provides broad prospects for solving the problem of energy shortage. In 100, 500, and 1,000 years, the fossil energy on the earth may face exhaustion. Only by relying on chemical and chemical industry to develop renewable resources and clean energy can the sustainable development of the economy and society be ensured. "
Jinyong realizes that popularizing chemical and chemical knowledge to the society, especially providing correct guidance to young people, so that they know that our world will be more beautiful because of the chemical industry, has become a work that must be done quickly.
In 2009, initiated by Academician Jin Yong, and 43 academicians of the Chinese Academy of Sciences jointly published the initiative "Revitalize Chemistry and Chemical Engineering Education, Start from Middle School Students", calling on the popular science education of chemistry and chemical engineering to let more young students understand the cutting-edge progress of the chemistry and chemical engineering major. In 2010, the project "Research on the Optimization and Connection of High School Chemistry and Engineering Education and my country's Economic and Social Development" was approved by the Chinese Academy of Engineering. In 2012, the project was listed as a key funded project of the Chinese Academy of Engineering and the China Science and Technology Association, respectively.
is composed of Academician Jin Yong, a project implementation team composed of a teacher in the Department of Chemical Engineering of Tsinghua University. Many academicians and dozens of experts engaged in teaching and research in universities and research institutions, enthusiastically participated in the production of short films and the compilation of popular science books. With almost no ready-made materials available, academicians and experts started from scratch and repeatedly explored hundreds of seminars and revised meetings, repeatedly polished and revised the details of various aspects.
After 6 years of unremitting efforts, in May 2016, a short video titled "Exploring the Future World of Chemistry and Chemical Engineering" and a supporting popular science book were finally published by Tsinghua University Press. "We do this for free, just to keep the heart of letting young people understand chemistry and chemical engineering. It is enough to make some contributions to our country's chemistry and chemical engineering industry!" said Jin Yong. It is gratifying that after the popular science video was launched, it was warmly welcomed by young students. The project team conducted trial screenings in many universities and middle schools such as the Department of Chemical Engineering of Tsinghua University. The students generally expressed it inspiringly and raised their understanding of chemistry and chemical engineering in the 21st century.
Since 2014, Jin Yong, as the main speaker of the "Beautiful Chemical Engineering" university tour speech, has successively visited East China University of Science and Technology , Beijing University of Chemical Technology , Dalian University of Technology, Wenzhou University and other universities, bringing the new concept of "Beautiful Chemical Engineering" to thousands of students. With a unique and fresh perspective and easy-to-understand explanation, it has given the first enlightenment class of the scientific truth of "Beautiful Chemical Engineering" for the majority of chemical engineering students.
In addition to going to colleges and universities to preach "beautiful chemicals", Jinyong also took advantage of various opportunities to recommend "beautiful chemicals" to the vast number of chemical enterprises and parks. In addition, with the strong support of Jin Yong and others, the China Petroleum and Chemical Popular Science Alliance was established in Beijing on June 5, 2016.Because of his consistent and outstanding contribution in advocating "beautiful chemical industry", Jin Yong was elected as one of the top ten figures in the "Belgian Chemical Industry-First 12th Five-Year Plan" at the "Beautiful Chemical Industry-First 12th Five-Year Plan" co-organized by the China Petroleum and Chemical Industry Federation and China Chemical Newspaper on January 15, 2016.

teaches and preaches
Academic inheritance "Four Generations in the same family"
In Jin Yong's eyes, he gradually grew from a student to a teacher, thanks to his experience in studying at Tianjin University . At that time, Jin Yong also served as an assistant teacher to Mr. Ding Xuhuai, an early Chinese chemical engineer and educator. Mr. Ding Xuhuai is a veteran of Chinese chemical engineering and has profound academic attainments. During the weekly Q&A session, regardless of whether there are students coming to ask questions, the old man always insists on leaving until the get out of class is over. Jin Yong took advantage of the opportunity to participate in the Q&A to ask Mr. Ding Xuhuai for advice on his own questions. Mr. Ding gave detailed and patient answers, and brought him home to let him read the information he had collected and sorted for many years. In this way, Jin Yong became Mr. Ding’s "disciple" in two years at Tianjin University.
From Mr. Ding Xuhuai, Jin Yong improved his understanding of chemical science, and also felt the old man's openness and selflessness and the character of supporting future generations. This experience is not only a portrayal of the relationship between Jin Yong and Mr. Ding Xuhuai, but also a footnote to the intimate relationship between Jin Yong and his colleagues and students in the future.
According to Jin Yong's colleagues and students, Jin Yong took the lead and did it himself, whether in the factory or in the laboratory. When removing the old insulation packaging of the equipment, the glass wool flew up, making the whole body itchy. However, Jin Yong always acted with the students and never heard him say he was tired or dirty. The test sampling point is at the top of the reactor more than ten meters high, and most people will feel dizzy when standing up. Every time you take a sample, Jinhong climbs up the top of the reactor along a very steep steel ladder and guides the sampling personally.
Jin Yong's students would praise him when talking about his usual guidance, which was hand-drawn drawings. In work, Jinyong's discipline positioning, scientific research positioning, and scientific research route selection are more accurate and forward-looking than ordinary people, and can always propose innovative designs. He was able to draw sketches by hand, communicate with the equipment processing personnel, debug and observe them personally until the experiment was successful.
Jin Yong's spirit of research subtly influenced the students. In the Tsinghua University Reaction Engineering Research Office he founded, 6 special scholarship winners, 5 Tsinghua University "Academic Rookies" and 4 National Outstanding Doctoral Thesis Award winners came out. Research groups like this that have been passed down from four generations are rare in Tsinghua Park.
In order to reward more outstanding students to participate in chemical research, and to encourage and encourage students in the school's chemical engineering department to work hard and be proactive and become chemical talents with excellent character and academic performance, the "Jinyong Scholarship Fund" named after Jinyong was established at Tsinghua University in January 2011. Jinyong will receive the bonus from the Guanghua Engineering Technology Award, the consultation fee obtained from serving the factory over the past few years, and the remuneration for going out to give lectures and presentations, totaling more than 400,000 yuan, all donated to the "Jinyong Scholarship". Now, the fund has expanded to millions of yuan with the help of graduates. (Chen Fei, picture provided by the school)
