Problems solved by technology

[0006] The invention provides an auxiliary agent for improving the quality of waste lubricating oil after regenerating finished products and a preparation method thereof, which overcomes the above-mentioned deficiencies in the prior art, and can effectively solve the problem that the current pickling process of waste lubricating oil regeneration process cannot realize waste lubricating oil For the effective regeneration of oil, a large amount of waste lubricating oil is discarded, landfilled, and incinerated, which makes the transformation and utilization of resources unreasonable, causes secondary pollution to the environment, and causes a serious waste of lubricating oil resources.

Embodiment 1

[0020] Embodiment 1, the auxiliary raw material for improving the quality of the finished product after the regeneration of waste lubricating oil includes 80% to 85% of organic alkalis, 1% to 5% of inorganic alkalis, and 5% to 10% of caking Dispersant, 1% to 5% of adsorbent and the balance of co-solvent.

Embodiment 2

[0021] Embodiment 2, the auxiliary agent for improving the finished product quality after the regeneration of waste lubricating oil comprises 80% or 85% of organic bases, 1% or to 5% of inorganic bases, 5% or 10% of caking Dispersant, 1% or 5% adsorbent and the balance of co-solvent.

[0022] Organic bases and inorganic bases are blended, bonded and interacted to effectively reduce the content of unsaturated substances such as olefins and alkynes in waste engine oil. It can neutralize acidic substances in waste engine oil, such as a small amount of mercaptans, aldehydes, ketones and other acidic substances in waste engine oil, so that the acid value of the finished base oil can be effectively reduced, and a small amount of adsorbent can be added to effectively absorb colloids in waste engine oil , asphaltene and other organic impurities, reduce the oil cracking reaction caused by colloids and asphaltene in waste engine oil during processing, and eliminate the production of lig...

Embodiment 3

[0024] Embodiment 3, as the optimization of embodiment 1 and embodiment 2, organic bases are quaternary ammonium bases; or / and, inorganic bases are inorganic sodium alkali salts or inorganic potassium alkali salts; or / and, bonding dispersion The agent is modified bentonite or activated bentonite; or / and, the adsorbent is activated carbon or activated clay; or / and, the cosolvent is carbonamide. The solubility and alkali value of quaternary ammonium base are the best, which is most suitable for the present invention; modified bentonite and activated bentonite have large pore size, and fine particles are easy to suspend; activated carbon and activated clay both have large pore size and fine particle characteristics, and the adsorption effect Good; carbonamides have good hydrophilicity and lipophilicity.

Abstract

The invention relates to the technical field of waste lubricating oil regeneration, in particular to an aid for improving the quality of a finished product after regeneration of the waste lubricatingoil and a preparation method of the aid. The aid is prepared from raw materials in percentage by weight as follows: organic alkali, inorganic alkali, a bonding dispersant, an adsorbent and a cosolvent. With adoption of the aid for regeneration of the waste lubricating oil, the quality of obtained finished base oil is stable, the problems of color reversion, darkening and stink smell of the finished base oil are solved, and the aid has good oxidation stability; after the waste oil is regenerated, bottom oil is easy to pump, internal purging, slag cleaning and other work of the device are reduced, and the processing capacity and the safety production coefficient of the device are improved; the oil at room temperature is long in storage time, smells normal and is free of burnt odor, acidic odor and other disagreeable taste. With adoption of the aid for regeneration of the waste lubricating oil, reasonable conversion utilization of resources can be realized, secondary pollution to the environment is avoided, and serious waste of the lubricating oil resources is avoided.

Description

technical field [0001] The invention relates to the technical field of regeneration of waste lubricating oil, and relates to an additive for improving the quality of regenerated waste lubricating oil and a preparation method thereof. Background technique [0002] At present, my country has become the world's second largest consumer of lubricants after the United States. With the development of the economy, the demand for lubricating oil is also increasing. my country's lubricating oil market will continue to grow at an annual rate of 5% in the next five years. By the end of 2015, my country's lubricating oil consumption will exceed 8 million tons. In 2020, my country's lubricant consumption will surpass that of the United States. The increasing demand for lubricating oil makes the amount of used lubricating oil replaced every year more and more. The amount of used lubricating oil replaced in my country accounts for about 30% to 40% of the total amount of lubricating oil. As...
