Plastic to fuel conversion process

In fact, the plastic fuel conversion process can also be referred to as a plastic pyrolysis process. This process is mainly the use of pyrolysis chemical reactions, the process of cracking waste plastics into fuel oil, carbon black, and flammable gases. In general, the plastic fuel process can be described as follows:

First, waste plastics are fed into the reactor via an automatic feeder and coal, wood, and natural gas are used to heat the reactor. When the temperature rises above 230 degrees, oil and gas will be produced.

Second, the produced oil and gas enters the condensing system. After a three-stage condensing system, oil and gas are liquefied into heavy oil and fall into the tank.

Once again, the heavy oil collected is desulfurized and degreasing, and the final result is fuel.

Then, the carbon black produced during the combustion process will be discharged through the underground sealed slag discharge channel, ensuring that the carbon black will not flutter during the discharge process, causing secondary air pollution.

Finally, the flue gas generated during the combustion process will be sprayed with three layers of water to clean the solid particles contained in the smoke. If coal, firewood or heavy oil is used as fuel, the generated flue gas will be relatively high. In view of this situation, DoingGroup Pulse dry dedusting device was introduced. Both smoke removal devices can ultimately achieve pollution-free emissions of smoke.

Pyrolysis rate of different kinds of waste plastics:

Raw Materials Project Fuel Oil
Waste plastic PE 85%-95%
PP 80%-90%
PS 80%-90%
ABS 40%
Pure white plastic 60%-70%
Fishing net, safety net 45%-50%
Plastic brand 20%
Pulp 20%-30%
Daily Garbage 30%-50%
Pure plastic cable 60%-80%
Pure purchase package 50%

As a leading domestic manufacturer and supplier of pyrolysis equipment, DoingGroup's used plastic fuel conversion equipment not only has 5% oil increase, 30%-40% energy saving, and 100% safety, but also has different models, which can be funded according to funds. Budget and actual needs choose the equipment that suits you!!

There is no doubt that the entire pyrolysis process is safe, energy-efficient and environmentally friendly. At the same time, we can get 45-50% of combustible oil, 30% of carbon black, and 5% of combustible gas from the waste plastic pyrolysis. They are widely used in different areas:

pyrolysis plant oil
Fuel oil application

(1) Waste plastic oil can be widely used in iron and steel, boiler plants, ceramics, electric power or chemical industries or hotel, hotel and other industries fuel oil, or for generating electricity generating units.

pyrolysis plant carbon black
Carbon black application


(2) Carbon black can be used for clay building bricks or as a fuel.

(3) Some combustible gases can be recycled to heat the reactor with fuel, which will save energy for the entire process.
