POLYMETALLIC CATALYST WITH STRONG INTER-METAL INTERACTION Russian patent published in 2014 - IPC B01J23/62 B01J27/13 B01J27/185 B01J27/186 C10G35/09 

FIELD: chemistry.

SUBSTANCE: invention relates to the field of hydrocarbon conversion. Claimed is a catalyst for catalytic reforming of a hydrocarbon raw material, which contains at least one metal M of a group of platinum, tin, a phosphorus promoter, a halogen-containing compound, a porous substrate and at least one promoter X1, selected from the group, consisting of gallium and indium. The said catalyst in a reduced form demonstrates, in accordance with Mossbauer spectroscopy ¹¹⁹Sn, a signal, which has a value of quadrupole splitting from 0 to 0.45 mm/s and a chemical shift IS from 1.5 to 2.4 mm/s relative to CaSnO₃, with an area of the said signal constituting from 1 to 30% of the total surface of signals. The catalyst is obtained by a method, including the introduction of the said promoter X1 and phosphorus at the stage of the substrate preparation.

EFFECT: increase of selectivity with respect to C5+ compounds and reduction of coke formation.
