What product can be obtained from recycling waste plastic?

The molecules of different plastic are very different, so the final product and oil yield are different. Generally, there are four kinds of final products that can be obtained from recycling plastics: hydrocarbon gas(C1-C5), oil (gasoline is C5- C11, diesel oil is C12-C20, the heavy oil is C20), paraffin and coke.

Based on the recycling of waste into energy and reuse, Henan Doing Environmental Protection Technology Co., Ltd. has developed and designed pyrolysis machines for recycling waste plastics into industrial fuel oil, carbon black, syngas, etc.

Waste plastic to fuel oil and carbon black pyrolysis plant

How does the pyrolysis machine work to recycle waste plastics into oil? Here is the working process:

1. Feeding part

Fill the reactor with waste plastic.

2. Pyrolysis part

In this process, the temperature in the reactor gradually increases. When the temperature gets high to a certain extent and the waste plastic will be decomposed and oil gas will come out. Totally about 40% -80% fuel oil comes out from waste plastic, mainly depends on the plastic types. Also, there is about 10% condensable gas that can go back to the reactor as the heating fuel after purification.

3. Cooling reactor part

The DOING pyrolysis machine is equipped with 8 tuyeres to extract the hot air, so that the reactor is quickly cooled and ready for next pyrolysis process, which is efficient.

4. Discharge carbon black part

In total, you can get about 15%~30% carbon black.

DOING Company has been focusing on the research and development of waste plastic pyrolysis machines for more than 13 years, constantly innovating production technology, and strictly controlling the production quality of machines. The plastic pyrolysis technology and operation of DY pyrolysis machines are easy, safe and stable. And our pyrolysis machines have passed GB/T 19001-2016/ISO 9001:2015 international quality system certification, EU CE certification and SGS certification.
