Compound additive applied in biodiesel

Abstract

The invention belongs to the technical field of petroleum additives, particularly relates to a compound additive applied in biodiesel. The compound additive applied in biodiesel comprises the following components in parts by weight: 5-20 parts of an antioxidant, 10-20 parts of fire promoting agent, 10-30 parts of a lubricant, 30-50 parts of a heat stabilizer, and 50-80 parts of solvent oil. The compound additive provided by the invention can enable the physical and chemical indictors of biodiesel to meet GB252-2000 standard, has good stability, less exhaust discharge amount, improves environment, and can increase power and reduce carbon residue ash content.

Description

technical field [0001] The invention belongs to the technical field of petroleum additives, in particular to a composite additive applied to biodiesel. Background technique [0002] Biodiesel mainly refers to fatty acid esters obtained through transesterification of animal and vegetable oils and short-chain alcohols under the action of a catalyst. Its combustion performance is close to that of diesel, but it is more environmentally friendly and renewable. As a green and renewable alternative energy, biodiesel has already attracted the attention of countries all over the world. Many countries have formed an industrial scale and formulated relevant standards and policies. Our country started late, but with the start of the biofuel oil technology development project of the "Tenth Five-Year Plan" scientific and technological research plan, the research on biodiesel in my country has become more and more popular in recent years. [0003] However, when biodiesel fuel is used, i...
