METHOD FOR HYDROCONVERSION OF HEAVY HYDROCARBON RAW MATERIALS IN HYBRID REACTOR Russian patent published in 2022 - IPC C10G45/08 C10G45/12 C10G45/50 C10G45/54 B01J37/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for hydroconversion of heavy hydrocarbon raw materials in the presence of hydrogen, at least one solid catalyst on substrate and at least one dispersed solid catalyst obtained from at least one salt of heteropolyanion, combining molybdenum and at least one metal selected from cobalt and nickel in a Strandberg, Keggin, lacunar Keggin or substituted lacunar Keggin structure. The method includes at least one of following stages: a) preparation of an aqueous solution containing the specified at least one salt of heteropolyanion; b) preliminary mixing of the aqueous solution with hydrocarbon oil to form a mixture of a dilute precursor, c) mixing of the aqueous solution obtained after the stage a) or mixing of the mixture of the dilute precursor obtained at the output of the stage b) with heavy hydrocarbon raw materials to form an active mixture, and d) carrying out the stage of hydroconversion of heavy hydrocarbon raw materials by introducing the specified aqueous solution obtained at the output of the stage a), or the specified mixture of the diluted precursor obtained at the output of the stage b), or the specified active mixture obtained at the output of the stage c), before or directly into a hydroconversion reactor containing at least one solid catalyst on substrate.

EFFECT: improvement of hydro-deasphalting and reduction in precipitation formation.
