Method for producing hydrocarbon-producing catalyst, hydrocarbon-producing catalyst, and method for producing hydrocarbon

Abstract

The present invention relates to a method for producing a hydrocarbon-producing catalyst for producing a hydrocarbon from a mixed gas of carbon monoxide and hydrogen and provides a method for producing, with stability and at high productivity, a hydrocarbon-producing catalyst with which the rate of conversion of carbon monoxide to hydrocarbon is high, the methane selectivity is low, the high activity can be maintained over a long period, the desorption of the active metal is unlikely to occur, and the durability is excellent. The method includes a precursor film forming step of putting a sol solution of an active metal compound and a metal oxide precursor in contact with a heated catalyst carrierto form a precursor film on a surface of the catalyst carrier, and a hydrolysis step of gelling the precursor film by hydrolysis to form a metal oxide gel film, with the active metaldispersed uniformly, on the surface of the catalyst carrier
