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

摘要

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 carrier 2 to form a precursor film on a surface of the catalyst carrier 2, and a hydrolysis step of gelling the precursor film by hydrolysis to form a metal oxide gel film 4, with the active metal 6 dispersed uniformly, on the surface of the catalyst carrier 2.

1. A method for producing a hydrocarbon-producing catalyst, the method comprising:
putting a sol solution of an active metal compound and a metal oxide precursor in contact with a heated catalyst carrier, to form a precursor film on a surface of the catalyst carrier; and gelling the precursor film by hydrolysis, to form a metal oxide gel film, with the active metal dispersed uniformly, on the surface of the catalyst carrier, wherein a molar ratio of the active metal with respect to the metal oxide, active metal/metal oxide, in the metal oxide gel film with the active metal dispersed uniformly, is 1.5 to 2.4.
