Many people's first reaction is that it is harmful to health

But if you use it correctly

gutter oil can also play its value

Recently

An A350 aircraft was received by Air China

The aircraft used 5% sustainable fuel for the first flight

The raw material is gutter oil

Use independent intellectual property technology to produce

Large aircraft drank "gutter oil"

Not only can sail normally

can also achieve green flight

html ml1 Aviation industry has made a key breakthrough in emission reduction

developed by the Sinopec Petrochemical Research Institute

my country's first bio-aerospace coal industrial device

This set of devices uses used cooking oil and edible oil

i.e. gutter oil

as raw material for production of bio-aero coal

(bio-aero coal:

is a aviation kerosene produced with renewable resources as raw material.

Raw materials mainly include

ml3

Career waste oil, animal and vegetable oil, agricultural and forestry waste, etc.)

Compared with traditional petroleum-based aviation kerosene

Bio aviation coal life cycle Carbon dioxide emission

Can emission

up to 50% of emissions can be reduced by more than 50%

This device can "swallow" about 100,000 tons per year" Gutter oil"

"spout" 40,000 tonnes of clear Bioaero kerosene

Convert to reduce carbon dioxide emissions by about 80,000 tons per year

equivalent to nearly 50,000 economical cars that are stopped for one year

"gutter oil" turns waste into treasure

The biggest difficulty lies in

Gutter oil contains a large number of fatty acid compounds

Its oxygen content is as high as about 11%

Traditional raw materials -

The oxygen content of petroleum is less than 0.1%

The difference is more than 100 times

Oxygen molecules directly affect the activity and stability of the catalyst of the refining device

In addition, the gutter oil also contains

sulfur, chlorine, metal elements and other impurities

. All of them must be removed one by one.

For this reason, Sinopec independently developed

special catalyst and process

and passed the demonstration verification of industrial scale device
