Problems solved by technology

At present, except for a small number of people who use coffee grounds as fertilizer and fuel, most of them are burned or landfilled as ordinary garbage, which brings a great burden to garbage disposal and wastes the economic benefits of coffee grounds themselves.
In the process of metal processing and equipment operation, it is often necessary to use lubricating oil to reduce friction and make the operation smoother. As a large industrial country, a large amount of lubricating oil is used every day, but the lubricating oil is generally not recycled well during use. , which has a great impact on the soil, the atmosphere, and even the health of operators

Abstract

The invention belongs to the technical field of lubricating oil and particularly relates to a production process for preparing the lubricating oil through coffee residue oil. The extracted coffee residue oil is used for manufacturing a surface active agent, meanwhile, the coffee residue oil is used as base oil of the lubricating oil, and the high antioxidant property of the coffee residue oil andthe natural fragrance of the coffee residue oil are utilized. According to the production process for preparing the lubricating oil through the coffee residue oil, coffee residue generated by a coffeemarket is effectively utilized, and the healthier and more environment-friendly effects are realized.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, and in particular relates to a production process for preparing lubricating oil by using coffee grounds oil. Background technique [0002] The market of the coffee industry is very large. China is a big consumer of coffee. Hundreds of millions of tons of coffee grounds are produced every year. Coffee grounds are not useless. The coffee grounds themselves have a coffee aroma, and the coffee grounds oil extracted from them also has a natural aroma. At present, except for a small number of people who use coffee grounds as fertilizer and fuel, most of them are burned or landfilled as ordinary garbage, which brings a great burden to garbage disposal and wastes the economic benefits of coffee grounds themselves. In the process of metal processing and equipment operation, it is often necessary to use lubricating oil to reduce friction and make the operation smoother. As a large industrial countr...
