Heavy oil auxiliary

Abstract

The invention discloses a heavy oil auxiliary, which is formed by stirring 18%-30% (by weight) of 0# diesel, 10%-20% of biodiesel, 8%-12% of viscosity reducer, 8%-12% of decomposer, 12%-15% of smoke remover, 10%-15% of naphthenic acid and 5%-8% of stabilizer for 3.5-4.5 hours at 70 to 100 DEG C, wherein the addition weight of heavy oil during the processing accounts for 0.5% of the weight of heavy oil to be processed. The heavy oil auxiliary is capable of greatly enhancing the quality of the processed heavy oil and bringing the heavy oil to sufficient combustion, thereby reducing air pollution and being favorable for environmental protection.

Description

Technical field: [0001] The invention relates to the field of petrochemical industry, in particular to a heavy oil additive used in heavy oil processing. Background technique: [0002] Heavy oil, also known as fuel oil, is the remaining heavy oil after gasoline and diesel oil are extracted from crude oil. It is mainly blended with atmospheric oil, vacuum residue, cracked residue, cracked diesel and catalytic diesel in the crude oil processing process. It is characterized by large molecular weight, high viscosity and difficult to volatilize. [0003] Due to its own characteristics, such as high viscosity and high freezing point, heavy oil has high flash point (such as 180°C) and low (20°C) due to the mixture of thin oil, so it is difficult to process uniformly; and the requirement for water makes heavy oil Difficult to process. Invention content: [0004] The technical problem to be solved by the present invention is to provide a heavy oil additive that can be added durin...
