Composite antioxidant and anti-adhesive agent for oil products and preparation method thereof

Abstract

The invention relates to a compound anti-oxidization anti-gelling agent for an oil product and a preparation method of the compound anti-oxidization anti-gelling agent and belongs to the technical field of oil gas additives. The compound anti-oxidization anti-gelling agent for the oil product is prepared from the following components in parts by weight: 1 to 2 parts of butylated hydroxyanisole, 0.5 to 1.5 parts of alkyl glycoside, 2 to 5 parts of stearic acid, 0.1 to 0.2 parts of triethylene glycol bi[beta-(3-tertiary butyl-4-hydroxy-5-methyl phenyl)propionate, 0.1 to 0.2 parts of bi(2,4-bitertiary butyl phenyl)pentaerythritol biphosphite, 1 to 2 parts of diosmetin, 1 to 3 parts of nano calcium carbonate, 15 to 19 parts of ethanol and 5 to 10 parts of glycerol. The compound anti-oxidization anti-gelling agent for the oil product has good stability; the performance of the compound anti-oxidization anti-gelling agent is not influenced after the compound anti-oxidization anti-gelling agent is stored for a long period; the oil product is prevented from color change when the oil product is stored; original colloid in the oil product can be completely removed and the formation of colloids is inhibited; the quality of the oil product is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of oil and gas additives, and in particular relates to a composite anti-oxidation and anti-adhesive agent for oil products and a preparation method thereof. Background technique [0002] Oil products usually refer to various petroleum products such as gasoline, kerosene, diesel oil and lubricating oil obtained after petroleum refining and other post-processing. Among them, gasoline, kerosene and diesel oil are also fuel oils, which are widely used in power plants to generate electricity, ship boiler fuel, heating furnace fuel, metallurgical furnace and other industrial furnace fuel. Fuel oil is the last product in the refining process, and its product quality control has strong particularity. The final formation of fuel oil products is restricted by many factors such as crude oil variety, processing technology, and processing depth. Fuel oil is mainly made of petroleum cracking residue and straight run resi...

Problems solved by technology

[0003] Whether it is fuel oil or lubricating oil, in order to ensure its performance in the production process, various additives will be added, and the antioxidant and anti-adhesive agent is mainly used for the addition of fuel oil, because fuel oil generally has more or less Contains impurities such as colloids, a small amount of colloids has little effect on the performance of the oil, but if the colloids in the oil are not removed in time, the content of the colloids will gradually increase as time goes by. Its performance will be greatly reduced, and it will cause blockage and seriously affect the combustion effect. Therefore, the research on anti-oxidation and anti-adhesive agents is extremely important.
