How is used engine oil recycled into diesel?

Used engine oil can be recycled into diesel like fuel through our used engine oil refinery machine. After proper treatment, the diesel got from used engine oil can be even used for diesel cars. How is used engine oil refined? Let's see the refining process of our used engine oil refinery machine.

Waste engine oil to diesel machine

Our used engine oil refinery machine has different models and processing capacities, among which our 10ton latest used engine oil refinery machine is very popular with our foreign customers due to its high efficiency and safety. So here just takes DOING 10TPD latest used engine oil refinery machine for an example.

1st-step recycling process --used engine oil cracking distillation.

Used engine oil belongs to heavy oil, mainly composed of long-chain hydrocarbon, which is heavier and has higher density and flash point than diesel fuel. To make it become lighter, its long-chain hydrocarbon has to be cracked down into the short one, so the first step is cracking distillation.

2nd -step recycling process --Decoloring and catalytic pyrolysis

In this process, the distillation oil gas will go through the catalytic tower of our used engine oil refinery machine for further refining. Two different kinds of catalysts inside the tower work together to purify the distillation oil gas and meanwhile pyrolyze some heaver oil gas.

3rd-step recycling process--Distillation oil gas cooling

The distillation oil gas after catalytic treatment will flow into the cooling system of our used engine oil refinery machine to cool down and then collected into temporary oil tanks.

4th -step recycling process-- Distillation oil further decoloring and purification

This process is optional, but if you wanna use the diesel got from used motor oil for some transportation vehicles, this step is very necessary because it can ensure the final oil is pure and transparent, which is good for engines.

The above is the general recycling process of how used engine oil can be recycled into diesel.
