Problems solved by technology

In this patent, only coal chemical products are used to blend fuel oil. The viscosity and density of the product are not easy to control. There is no light oil component. The atomization of fuel oil is not good during combustion, resulting in insufficient combustion and low heat energy utilization.

Abstract

The invention relates to a fuel oil composition suitable for bunker fuel oil industry, industrial generation, civil boilers and the like. The fuel oil composition comprises the following materials: 10-60 parts by weight of heavy oil residues as petroleum byproducts, 5-50 parts by weight of low-temperature coal tar, 5-53 parts by weight of light fuel oil and 2-20 parts by weight of diesel oil or absorber oil. A fuel oil finished product prepared from the fuel oil composition has the advantages of good cleanness and stability, low abrasion and corrosion effects on combustion equipment and favorable storage stability.

Description

technical field [0001] The invention belongs to an economical fuel oil composition with good storage stability, which is suitable for marine fuel oil, industrial power generation, civil boilers and other industries. Background technique [0002] Fuel oil used in industries such as marine fuel oil, industrial and civil boilers is blended by mixing light component oil into heavy residual oil components. Adding more than a certain proportion of light oil will completely break the compatibility between asphaltenes and colloids in residual oil, resulting in the precipitation of asphaltene and colloids in fuel oil, and stratification and storage will occur during fuel storage and use. Tank deposits, centrifuge overload and filter clogging, etc., so fuel oil must have good storage stability and compatibility between components. Therefore, many manufacturers mostly use oil slurry with more aromatic components to generate fuel oil. [0003] Fuel oil fractionated from catalytic and ...
