CATALYST FOR STEAM REFORMING OF OIL AND HYDROCARBON GASES Russian patent published in 2017 - IPC B01J23/78 B01J21/04 B01J21/16 C01B3/38 

FIELD: chemistry.

SUBSTANCE: catalyst described steam reforming of naphtha and hydrocarbon gases containing oxides of nickel, magnesium, calcium, potassium and aluminium. The composition of the raw material for the preparation of the support includes alumina, a structure-forming additive and kaolin, with the following component ratio, wt %: a build-up additive of 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 resultant catalyst has the following chemical composition, in wt %: nickel oxide 5.0-16.0; 1.8-5.3 magnesium oxide; calcium oxide 1.50-5.1; 3.4-5.5 potassium oxide; alumina 1.0-3.8; carrier the complement to 100.

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.
