Assistant for heavy oil hydrogenation cracking

Abstract

An auxiliary for hydrogenation cracking heavy oils contains one or a combination of any both or above selected from halogen elementary substance, halogen hydride, hypohalous acid and its salts, sub-halogen acid and its salts, halogen acid and its salts, homo-halogen acid and its salts, organic halogenide, organic carboxylic acid halogen, organic sulphonic acid halogen with ratio of 10-6000ug/g. It can be used for suspending bed or fixed bed hydrogenation of wax oil or residual oil, and residual oil visbreaking or coking or fluid catalyst cracking, and co-rendering with coal or waste plastics or waste rubbers. By adding it yield percentage of light oil is effectively increased under the same conditions with less higher coke rate.

Description

Technical field: [0001] The invention relates to an additive for heavy oil, and belongs to the technical fields of petroleum processing and petrochemical industry. The additive can be used in the hydrogenation process of wax oil or residual oil suspended bed, the fixed bed hydrocracking process of wax oil or residual oil, and can also be used in the process of visbreaking of residual oil, coking of residual oil, and fluidized catalytic cracking process of residual oil , can also be applied to the co-refining process of residue oil and coal, residue oil and waste plastics, residue oil and waste rubber. Applied to the above process, under the same reaction conditions, after adding a small amount of this cracking aid, the coke formation rate in the above process will not increase or slightly increase, and more importantly, the wax oil and residual oil in the above process can be greatly improved. And the cracking conversion rate of its co-refined products can increase the yield ...
