1, hazardous waste business license. 2, dangerous goods transport license. 3. Business license. The first step of waste oil recovery is to add a special catalyst to the recovered waste oil, and then carry out catalytic cracking at a moderate temperature, so that the organic components in the waste oil can be effectively cracked.

Recycling used engine oil requires a hazardous waste business license.

What is waste engine oil?

The so-called "waste engine oil" usually refers to impurities such as moisture, dust, other miscellaneous oil or metal powder produced by the wear of machine parts, which leads to the black color and increased viscosity of engine oil!

For example, the engine oil changed during the maintenance of our car and the lubricating oil used on the equipment belong to waste engine oil.

Of course, there are also some engine oils that deteriorate due to improper storage, resulting in organic acids, gums and asphaltenes, also known as waste engine oil!

What is the function of waste engine oil?

1. Waste engine oil can be used to refine diesel oil.

In fact, the recovered waste engine oil can be refined into diesel or gasoline after a series of treatments!

The main technological process is dehydration and impurity removal, and then pyrolysis is completed under the action of catalyst and high temperature.

The next step is acid-base refining and clay refining, and finally distillation treatment, so that the corresponding products can be recycled.

Although the cetane number of diesel oil extracted from waste engine oil can reach 40, it usually needs deodorization before it can be used normally because of its deviation and unpleasant smell!

2. Engine oil can be used as the raw material of release agent.

Now many chemical plants will use waste engine oil as the raw material of release agent, and its production process is very simple!

Just mix diesel oil, waste engine oil, vegetable oil, liquid paraffin, aromatic and preservative in a certain proportion.

Then fully stir 10-20 minutes until all the materials are stirred evenly, and an excellent release agent is made.

The release agent made by this method is especially suitable for demoulding between foamed concrete and metal mold, and is widely used in the production of light partition board and non-steaming block at present!

3. Waste engine oil can be directly used as release agent.

In fact, waste engine oil can be used not only as the raw material of release agent, but also as a simple release agent.

If you are a construction worker, you must know that waste engine oil exists as a concrete release agent on the construction site!

It can not only prevent concrete from sticking to building formwork, but also play a certain role in rust prevention and corrosion protection.

Legal basis:

Measures for the administration of hazardous waste business license Article 2 Units engaged in the collection, storage and disposal of hazardous waste within the territory of People's Republic of China (PRC) shall obtain a hazardous waste business license in accordance with the provisions of these Measures. Article 3 The business license for hazardous wastes is divided into the comprehensive business license for collection, storage and disposal of hazardous wastes and the business license for collection of hazardous wastes. Units that have obtained the license for comprehensive operation of hazardous wastes may engage in the collection, storage and disposal of all kinds of hazardous wastes; Units that receive the license for hazardous waste collection and operation can only engage in hazardous waste collection and operation activities of waste mineral oil generated in motor vehicle maintenance activities and waste cadmium-nickel batteries generated in residents' daily lives.
