How to refine pyrolysis oil to remove odor and black color?

Pyrolysis oil is a type of heavy oil obtained from waste tires/plastics with the pyrolysis machine, which can be used in the cement factory, steel factory, glass factory as heating fuels or in the heavy oil machinery. But it can't be used in the diesel generator, so if you have the higher requirements about the quality of the fuel oil, you can use our pyrolysis oil distillation plant to remove the odor and black color. Then today, this passage will show you how to refine pyrolysis oil to remove odor and black color with the pyrolysis oil distillation plant:

Applications of pyrolysis oil

As a reliable manufacturer and supplier of pyrolysis oil distillation plant, DOING engineer team has developed two types of pyrolysis oil distillation plants, which have their own designs and advantages to meet the various demands of our customers:

1. Liquid catalyst pyrolysis oil distillation plant

This type of plant is suitable for customers looking for a more cost-effective option. It uses acid and alkali neutralization to remove color and odor from tire/plastic pyrolysis oils. Although the catalysts need to be changed daily, they are readily available on the market and are inexpensive.

The working process involves heating the pyrolysis oil until the oil gas comes out, after which it goes through the cooling system to obtain the liquid oil. Adding liquid catalysts removes the odor and black color from the pyrolysis oil.

2. Solid catalyst pyrolysis oil distillation plant

The solid catalysts used in the pyrolysis oil distillation plant are researched by our engineer team specially, which makes this type more environmentally friendly and advanced than the acid-alkali wash form. The solid catalysts used can be recycled, and each ton has a service life of about 600 tonnes of pyrolysis oil processing, so there is no need to replace them daily. However, they are relatively expensive compared to liquid catalyst designs.

The working process involves heating the pyrolysis oil until the oil gas comes out, then passing the gas through the catalyst and cooling systems to obtain the liquid diesel oil directly.

And if you have the higher requirements for the obtained diesel oil, DOING also can match the distillation plant with a further decolorization filtration system, which can make further refining to remove the odor and black color of the pyrolysis oil, and the resulting oil yield is essentially the same.

Depending on different customer requirements for the distillation plant and overall budget for the project, DOING will customize the most appropriate solution for each customer's situation.
