CATALYST APPLICABLE FOR HYDROPROCESSING, CONTAINING GROUP VIII AND VIB METALS, AND METHOD FOR PRODUCING WITH ACETIC ACID AND DIALKYL(C1-C4)SUCCINATE Russian patent published in 2015 - IPC B01J21/04 B01J23/74 B01J23/85 B01J27/19 B01J31/02 B01J31/04 B01J37/02 B01J37/08 C10G45/08 

FIELD: chemistry.

SUBSTANCE: invention refers to a catalyst for hydrocarbon material hydroprocessing. The presented catalyst comprises an amorphous alumina-based carrier, phosphorus, at least one dialkyl(C1-C4)succinate, acetic acid and a functional group with a hydrogenation/dehydrogenation ability containing at least one group VIB element and at least one group VIII element specified in cobalt and/or nickel. The Raman spectrum of the above catalyst has characteristic bands of at least one Keggin heteropolyanion within the range of 990 and/or 974 cm^-1, characteristic bands of said succinate and a principal characteristic band of acetic acid within 896 cm^-1. The invention also refers to a method for producing this catalyst and to the catalyst produced by this method, as well as to a method for hydrocarbon material hydroprocessing in the presence of this catalyst.

EFFECT: presented catalyst possesses overactivity shown in hydroprocessing by the synergetic action of a combination of acetic acid and dimethylsuccinate.
