Embodiment 1

[0019] An additive for regenerating waste oil from automobile engines, the additive is composed of 50% (mass concentration, the same below) calcium hydroxide aqueous solution, ammonium bisulfate and clay. The amount of calcium hydroxide added per ton of waste oil is 7.5kg, the amount of ammonium bisulfate added is 8kg, and the amount of clay added is 65kg.

[0020] The recycling process of automobile engine waste oil is as follows:

[0021] Collect the waste automobile engine oil in the oil tank and let it stand for 2 hours, discharge the water in the waste oil and separate the mechanical impurities in it; add calcium hydroxide aqueous solution after the overall temperature is raised to 50°C, and stir for 25 minutes; heat up to 75°C, Add ammonium bisulfate and stir for 20 minutes to fully react; let it settle for 24 hours to remove the sediment and trace water (less than 0.01%) present in the supernatant, and then add clay for refining to obtain base crude oil.

[0022] After...

Embodiment 2

[0024] An additive used for regeneration of automobile engine waste oil, the additive is composed of 40% sodium hydroxide aqueous solution, ammonium bisulfate and clay. The amount of sodium hydroxide added per ton of waste oil is 7kg, the amount of ammonium bisulfate added is 7kg, and the amount of clay added is 50kg.

[0025] The recycling process of automobile engine waste oil is as follows:

[0026] Put the waste automobile engine oil in the oil tank and let it stand for 1 hour, discharge the water in the waste oil and separate the mechanical impurities in it; add sodium hydroxide aqueous solution after the overall temperature is raised to 40°C, and stir for 20 minutes; heat up to 60°C, Add ammonium bisulfate and stir for 15 minutes to fully react; let it settle for 20 hours to remove the sediment and a small amount of water (less than 0.01%) in the supernatant, and then add clay for refining to obtain base crude oil.

[0027] After regeneration, the oil is yellow and tran...

Embodiment 3

[0029] An additive for regenerating waste oil of automobile engines, the additive is composed of 60% sodium carbonate aqueous solution, ammonia water and clay. The amount of sodium carbonate added per ton of waste oil is 8kg, the amount of diammonium hydrogen phosphate added is 9kg, and the amount of clay added is 80kg.

[0030] The recycling process of automobile engine waste oil is as follows:

[0031] Put the waste automobile engine oil in the oil tank and let it stand for 2 hours, discharge the water in the waste oil and separate the mechanical impurities in it; add sodium carbonate aqueous solution after the whole temperature rises to 55°C, and stir for 30 minutes; heat up to 70°C, add Stir the ammonia water for 25 minutes to fully react; let it settle for 22 hours to remove the sediment and trace water (less than 0.01%) present in the supernatant, and then add clay for refining to obtain base crude oil.

[0032] After regeneration, the oil is light yellow and transparen...

Abstract

The invention belongs to the technical field of waste oil regeneration, and in particular relates to an additive and a process for regeneration of waste oil for an automobile engine. The additive consists of a basic innorganic compound aqueous solution, hydride and carclazyte. The process provided by the invention is environmentally-friendly, and regeneration resource can be better utilized, thereby benefiting human beings and simultaneously solving the problems of high cost and low yield.

Description

technical field [0001] The invention belongs to the technical field of waste oil regeneration, and in particular relates to a regeneration process of automobile engine waste oil. Background technique [0002] Because oil resources are limited, it has become a development trend to try to recycle engine oil. However, the regeneration and treatment of existing automobile engine waste oil is a chaotic market. Some are cracked into diesel oil, but the produced diesel oil does not meet the national standard, and the smell is smelly and dark in color; some are treated with sulfuric acid, but the recovery rate Low, the base oil does not meet the national standard, the country's large refineries also have to go through sedimentation to separate the water slag, remove colloids, additives and heavy metals, and then carry out high-temperature, high-pressure, hydrocracking to obtain good quality. base crude oil, the cost of processing is high, and the profit is low. At the same time, t...
