Pyrolysis oil VS diesel

Pyrolysis oil and diesel are different in many aspects. Here let us explore their differences in produce, chemical composition and application.

1.Produce
Pyrolysis oil is the end product of waste plastics, rubbers and tyres pyrolysis. These waste materials contain oil components. Heat waste inside the pyrolysis plant under no-oxygen condition, then the waste tyre/plastic/rubber can be cracked into about 45% pyrolysis oil, 35% carbon black and 15% steel wire.

Waste tyres converted into pyrolysis oil

Diesel is the product of pyrolysis oil after refined by waste oil distillation machine. Besides, the waste engine/motor oil can also be turned into distillation diesel with this machine, too. The whole refining process includes distillation, cooling, decoloring and deodoring system with 80-85% high diesel output.

2.Composition
Pyrolysis oil contains a large amount of unsaturated compounds such as diolefins and aromatic hydrocarbons, which lead to its color to be dark brown if placed in the air, and there is a viscous polymer precipitate produced. The following is the SGS test report of DOING tyre pyrolysis oil for reference:

Diesel is mainly composed of carbon, hydrogen and some oxygen. The color is tea yellow or brown. waste oil distillation machine DOING group supplied can purify the pyrolysis or waste oil into lighter colored oil. The following is the SGS test report of DOING distillation diesel for reference:

3.Application
Pyrolysis oil is widely used as industrial fuel to substitute furnace oil or industrial diesel. Typical industrial applications of pyrolysis oil as a fuel, the fuel oil is mainly used in machine do not require high quality fuel oil, like steel factory, boiler heating, cement factory, even heavy oil generator etc. If refined, distillation diesel can be generated, which can be used for diesel generator, diesel fuel for heating, heavy machinery etc while not be used directly in automotive engines.
