How to make diesel from waste motor oil?

Converting waste motor oil into diesel fuel involves a process called oil distillation, oil refining or oil reprocessing. Here are the general steps to make diesel from waste motor oil:

First, to pump used motor oil into used motor oil into waste oil distillation plant.

Note: If your waste oil contains too much water or impurities, you can also filter the waste motor oil to remove solid particles and water, which can be achieved through processes such as settling, decanting, or centrifugation.

Second, we need to heat dirty waste motor oil and keep it at the best temperature for the best diesel quality. Distillation involves heating the oil in a fractionating column or distillation tower. Different components of the oil have different boiling points, allowing for the separation of various fractions. Fuel oil will be converted to oil gas when it gets heated.

Then our cooling system of waste oil distillation plant will cool oil gas to get liquid diesel.

Next pump diesel into odor and color removal system for further refining, which will purify further diesel with special liquid catalyst: acid and alkali solution. If you can't buy liquid catalyst, we also offer the solid catalyst solution, which can directly be bought from DOING Company at factory prices.

Finally, you can get 85% diesel from our waste motor oil to diesel distillation plant. And if you have a higher requirement for oil color, we also have auxiliary equipment for you to choose to improve diesel color, the white clay decolorization system and filter machine. As for the heavier fractions, such as residual oil or bitumen, remain at the bottom of the colum, which can be discharged for paving or for sale.
