According to Sinopec news, China's first bio-jet fuel industrial device was produced at Sinopec Zhenhai Refinery for the first time. means that my country's bio-jet fuel can achieve large-scale production and move towards large-scale production and commercialization. The application has taken a solid step forward.
The device has an annual design processing capacity of 100,000 tons. can basically digest the waste oil recycled in a city with a population of 10 million in a year. It can reduce carbon dioxide emissions by about 80,000 tons every year, which is equivalent to nearly 50,000 economical vehicles. The car stopped driving for a year.
What is bio-jet fuel?
Bio-jet fuel is aviation kerosene produced from renewable resources. The raw materials mainly include catering waste oil, animal and vegetable oils, agricultural and forestry waste, etc. Compared with traditional petroleum-based aviation kerosene, the full life cycle carbon dioxide emissions can be reduced by up to 50%.
The above-mentioned bio-jet fuel industrial device adopts the production technology developed by Sinopec Petrochemical Science Research Institute and uses used cooking oil and edible oil, that is, gutter oil, as raw materials to produce bio-jet fuel.
The raw materials for the first batch of bio-jet fuel come from two technology and environmental protection companies in Chengdu, Sichuan. The waste oil after meals was pre-treated and shipped to Ningbo .
It is estimated that in a city with a population of 10 million, the actual recycling volume of food waste oil is about 10,000 tons per month, and more than 100,000 tons of waste oil is recycled annually. Taking into account the conversion rate of gutter oil, if this set of equipment is operated at full capacity, it can basically digest the gutter oil recovered from a city with a population of 10 million in a year.
my country has become the fourth country in the world to have independently developed
bio-jet fuel technology.
Gutter oil contains a large amount of fatty acid compounds, and its oxygen content is as high as about 11%, while the traditional raw material - petroleum, has an oxygen content of less than 0.1%. The difference is more than 100 times.
Oxygen molecules directly affect the activity and stability of the catalyst in the refining unit. In addition, gutter oil also contains various impurities such as sulfur, chlorine, and metal elements, which must be removed one by one.
To this end, Sinopec has independently developed special catalysts and processes, which have been demonstrated and verified by industrial-scale devices.
In 2009, Sinopec started the research and development of bio-jet fuel.
obtained China's first bio-jet fuel airworthiness certificate in 2014, and has successively conducted commercial flights on domestic routes from Shanghai to Beijing, and transoceanic flights on international routes from Beijing to Chicago. my country has become the first in Asia and the world. The fourth country with independent research and development of bio-jet fuel technology.
In August 2020, China’s first large-scale industrialized device for bio-jet fuel was built at Zhenhai Refinery.
Zhenhai Refining and Chemical's 100,000 tons/year bio-jet fuel device
In May this year, Zhenhai Refining and Chemical Branch's oil hydrogenation (HEFA) route bio-jet fuel product passed the sustainable Biomaterials Roundtable (RSB) certification. This time The certification is the first global sustainability certification obtained by my country's bio-jet fuel products, indicating that Zhenhai Refinery's bio-jet fuel equipment, raw materials, production processes and products are in compliance with the basic principles and standards of RSB bio-fuel sustainable development.
Gutter oil also has these uses
// Gutter oil can produce biodiesel
B5 Biodiesel is a green energy that uses gutter oil and, after a series of biochemical reactions, is mixed with ordinary diesel in a ratio of 5:95. .
Compared with traditional vehicle diesel, B5 biodiesel has the characteristics of good environmental performance, wide source of raw materials, and renewable.
It is reported that B5 automotive diesel, a blended fuel composed of 5% biodiesel and 95% zero diesel, can reduce pollutant gas emissions such as heavy metals and fine particulate matter by more than 10%, and the nitrogen oxide purification efficiency reaches 80 %.Taking Sinopec Shanghai Petroleum as an example, since the pilot launch of B5 vehicle diesel refueling in 2017, more than 20 million vehicles have been refueled with B5 vehicle diesel, with an average daily refueling of about 12,500 vehicles, which has helped digest food waste. More than 56,000 tons of biodiesel were produced from fats and oils.
In addition to environmental benefits, waste kitchen grease is made into biodiesel, which can be "normally" used in vehicle fuel, which can promote the management of waste kitchen grease, effectively solve the problem of waste oil returning to the table, and promote resource recycling.
Biodiesel has also been exported. In October 2017, nearly 900 tons of biodiesel from Chongqing were successfully exported to Portugal and the Netherlands.
Currently, the main sales channel for biodiesel is in Europe. The EU Renewable Energy Directive that will be implemented in 2021 requires that the blending ratio of biodiesel in the European road transportation industry be increased from 10% to 25%.
// Gutter oil transformed into drilling lubricant
As early as March 2012, researchers from the Chuanqing Drilling and Completion Fluids Research Institute of China National Petroleum Corporation used gutter oil as the basic crude material, purified, modified and complexed it. With the cooperation, we successfully developed the bio-oil lubricant for drilling fluids. This lubricant is beneficial to protecting the formation and reducing costs.
