I. Usage:

This technology utilized catalyzing treatment during chemical processing. Our company developed a kind of composite catalyst, through catalyzing, the harmful substances are selectively processed, for example, polymerization, shielding, passivation effect and discharged as residues, so as to remove the unstable factors of the waste lubricating oil, make it became qualified lubricating base oil.

This technology is different from the traditional distillation process with sulfuric acid,it is also different from the current hydrogenation technology. The process of this technology is: Catalyzing treatment of waste lube oil (including gasoline engine oil,diesel engine oil ect. almost all sorts of recyclable waste oil), and then distill to new lube base oil. The oil will not mean to oxidate and change color, no odour. The residues can be used as fuel, it will not make secondary pollution. This technology is high automatic, the operation is simple, no complicate operation control, easy to learn and understand, low labour intensity, 1-2 persons are enough and no special requirement.

II. Working principle

The used oil is mixed with catalyst in chemical treatment tank, then it is sent to distillation kettle to have it circulated and heated, while the temperature increasing, the oil gas is distilled out and cooled in to liquid through three stages cooling, they're separately stored in water, gasoline/diesel, light lube oil, heavy lube oil receivers. The noncondensable gas will be sent to the furnace of boiler to have it burned and discharged after pass through waste gas disposer to ensure "zero "discharge of waste gas, The residues can be utilized as fuel to avoid pollution from it.

III. Technical features

1\Applicable to wide range of used oil:All sorts lube oil(Gasoline engine oil, diesel engine oil etc. all waste lube oil);

2\No secondary pollution during processing:No waste gas, water disposal,oil sludge can be used as fuel.

3\Good quality products:Recycled oil will not change color and no odour.

4\Low processing cost; 

5\High regeneration rate;
