A catalyst is suggested for synthesis gas conversion to hydrocarbons, based on a zeolite with incorporated zinc dioxide and a binding agent. In order to increase the catalyst selectivity to ethane, the used zeolite is either pentasil in a sodium or hydrogen form, or zeolite Y and mordenite in protonated form. The zeolite contains 0.74-10.7 wt.% zinc oxide. Silica is used as the binding agent, mass ratio being as follows (wt.%)

Zinc oxide 82-87
Silica 13-18

The catalyst having improved selectivity is produced owing to the formation of a specific zeolite structure in the presence of hydroxy-compound and under specified synthesis conditions. The zeolite is treated with an aqueous solution of a zinc salt, dried and moulded.

A catalyst for the production of hydrocarbon consists essentially of crystalline aluminum silicate, at least one compound of the metal zinc and/or cadmium and additionally silica. The catalyst is produced by heating a crystalline aluminum silicate, in a given case partially or completely converted to the hydrogen form, with a zinc and/or cadmium compound and molding with a silica containing binder.
