What is industrial mixed oil?

The definition and classification of biodiesel is a typical green energy source. In the current context of "carbon peaking and carbon neutrality", biodiesel has broad development prospects due to its wide source of raw materials, good fuel combustion performance, strong environmental performance, and renewable characteristics. Whether it is promoting the replacement of new energy sources or reducing environmental pollution, it has important strategic significance.

According to the preparation method and final product classification, biodiesel can be divided into three categories: ① ester based biodiesel (FAME): first generation biodiesel, narrowly defined as biodiesel. Specifically, it refers to the transesterification reaction between various types of bio fats and methanol to generate corresponding fatty acid methyl esters, which are then separated from glycerol, washed with water, dried, and other appropriate treatments to obtain biodiesel. From the perspective of physical and chemical properties, the first generation of biodiesel has disadvantages such as poor low-temperature fluidity and unsuitable for long-term storage. Therefore, the first generation of biodiesel needs to be mixed with diesel, with a mixing ratio usually between 2% and 20% Hydrocarbon based biodiesel (HVO): Second generation biodiesel, also known as renewable diesel. It refers to the process of hydrogenation, deoxidation, isomerization, and cracking of bio fats to produce straight chain and branched chain alkane diesel fuel that is almost indistinguishable from petroleum based diesel fuel. Its chemical structure is no longer different from ordinary diesel fuel and can be directly used for vehicles without the need for blending Sustainable Aviation Fuel (SAF): An emerging aviation fuel that blends green aviation fuel made from biomass with traditional fuel in a certain proportion, and its carbon dioxide emissions can be reduced by 80% compared to traditional aviation fuel.
