Embodiment Construction

[0010] A waste engine oil regeneration method, the method is realized by the following steps: (1) filter the waste engine oil, and then inject it into the reaction kettle; (2) add 1.5% (or 2%, or 1.8%, or 2.5% of the weight of the waste engine oil, etc. ) concentration of 50% sodium hydroxide solution and 1% (or 1.2%, or 1.3%, or 1.5%, etc.) concentration of 30% hydrogen peroxide, stirring and heating the reactor, heating the waste engine oil to 80°C (or 82°C, or 85°C, or 87°C, or 90°C), and stand at this temperature for 8 hours (or 9, or 10, or 11, or 12 hours), the waste engine oil in the reactor For the upper and lower layers, the upper clarified liquid is separated from the sediment of the lower layer; (3) the upper clarified liquid is injected into the still, and the upper clarified liquid in the still is heated and subjected to atmospheric distillation to separate the clarified liquid in the upper layer. Light components and water, the gaseous substances distilled at atm...

Abstract

The invention relates to a regeneration technology of waste engine oil, in particular to a regeneration method of the waste engine oil. The regeneration method is used for solving the problem that the prior art has no regeneration method of the waste engine oil. The method is realized by adopting the following steps: (1) the filtration of the waste engine oil is carried out; (2) sodium hydroxide solution and hydrogen peroxide are added, the heating is further carried out till 80 to 90 DEG C, the still placement is carried out for 8 to 12 hours, the upper layer of clarified liquid and the lower layer of sediment are separated; (3) the upper layer of the clarified liquid is injected into a distillation kettle for carrying out the atmospheric distillation to obtain a diesel oil component; (4) when the temperature of the upper layer of the clarified liquid reaches 280 to 310 DEG C, the atmospheric distillation is stopped, the vacuum distillation is started to obtain vacuum distillation products, attapulgite with 3 to 8 percent of the weight of the vacuum distillation products is added therein; (5) benzotriazole fatty acid amine with 3 to 8 per mill of the weight of the engine oil component is further added for stirring, thereby obtaining regenerated engine oil product. The regeneration method of the waste engine oil has no pollution, high conversion rate and low regeneration cost, and all the indicators of the obtained regenerated engine oil can achieve the using standards. The method can be used for the regeneration of the waste engine oil with various sources.

Description

technical field [0001] The invention relates to waste engine oil regeneration technology, in particular to a waste engine oil regeneration method. Background technique [0002] The engines of automobiles, trains, ships, etc. must be lubricated with oil. The finished engine oil (also known as lubricating oil) contains heavy components with high boiling points, so it has good lubricating properties. During the use of finished engine oil, due to high temperature oxidation, part of the heavy components are decomposed into light components. When the light components and various colloids, sludge, and metal chips reach a certain level after being used for a certain period of time, the lubricating effect will decrease. Engine oil needs to be changed. At present, the reuse of waste engine oil is mainly to refine diesel oil by distillation, which has high pollution, low conversion rate and poor quality of diesel oil obtained. In the prior art, there are no systematic and effective ...
