METHOD OF PREPARATION OF THE CATALYST FOR STEAM REFORMING OF OIL AND HYDROCARBON GASES Russian patent published in 2017 - IPC B01J37/02 B01J23/78 B01J21/04 B01J21/16 

FIELD: chemistry.

SUBSTANCE: catalyst described steam reforming of naphtha and hydrocarbon gases containing oxides of nickel, magnesium, calcium, potassium and aluminium. The support is prepared by mixing alumina, a structure-forming additive and kaolin with the following component ratio, wt %: The building agent 6.9-8.5; kaolin 1.5-12.0; alumina balance to 100. In the preparation of the carrier, alumina and a structure-forming additive are premixed, after which the mixture is ground and the resulting milling is mixed with kaolin. The carrier moulded in the form of granules is dried and calcined. When preparing the catalyst, the carrier is impregnated with calcium with a magnesium solution (dolomite extract).

EFFECT: increase in stability, conversion rate, heat resistance, decrease in pressure drop and temperature, prevention of coking, catalyst destruction and increase in its service life, reduction of catalyst consumption and material costs are obtained not by the additive contribution of each component, but due to the total synergistic effect.
