CATALYST, SUITABLE FOR HYDROPROCESSING, CONTAINING METALS OF GROUPS VIII AND VIB, PHOSPHORUS, AND ITS OBTAINING WITH APPLICATION OF CITRIC ACID AND C1-C4-DIALKYLSUCCINATE Russian patent published in 2016 - IPC B01J21/04 B01J23/74 B01J23/85 B01J27/19 B01J31/02 B01J31/04 B01J37/02 B01J37/08 C10G45/08 

FIELD: chemistry.

SUBSTANCE: catalyst contains amorphous substrate based on aluminium oxide or alumosilicate C1-C4-dialkylsuccinate, citric acid, phosphorus and hydrating-dehydrating group, containing element of group VIII base elements and at least one group VIB element. Spectrum of catalyst Raman scattering contains bands 990 and/or 974 cm^-1, characteristic for at least one Keggin heteropolyanion, characteristic bands of said succinate and basic characteristic bands of citric acid, with quantity of phosphorus constituting from 0.1 to 20 wt %, quantity of group VIB element(s) constitutes from 5 to 40 wt %, quantity of group VIII element(s) constitutes from 1 to 10 wt %, with quantity of aluminium oxide or alumosilicate in substrate constituting more than 25 wt %, with dialkylsuccinate and citric acid being present in quantity, which corresponds to molar ratio of dialkylsuccinate to group VIB element(s), constituting from 0.15 to 2 mol/mol, and molar ratio of citric acid to group VIB element(s), constituting from 0.05 to 5 mol/mol.

EFFECT: improved hydrodesulphurising and hydrating abilities in comparison with traditional catalysts.
