Abstract
Catalyst for synthesis gas conversion in which a gas comprising carbon monoxide and hydrogen is converted to a liquid hydrocarbon is prepared by subjecting cobalt or nickel on a refractory metal oxide support to an activation procedure at a temperature of from about 100.degree. to about 450.degree. C. comprising, in sequence, (A) reduction in hydrogen, (B) oxidation in an oxygen-containing gas, and (C) reduction in hydrogen.
Claims38
A process for the preparation of a catalyst useful for conversion of synthesis gas to a product containing liquid hydrocarbons, said process comprising:
- (A) depositing cobalt or nickel precursor on a refractory metal oxide support by impregnation or
- precipitation to distribute cobalt or nickel as crystallites on said support to form a supported catalyst, and
- (B) activating said supported catalyst by subjecting said supported catalyst to the steps, in sequence, of
- (i) reduction in hydrogen gas, (ii) oxidation in an oxygen-containing gas and (iii) reduction in hydrogen gas, steps (i), (ii) and (iii) being conducted at a temperature of from about 100.degree. to about 450.degree. C. to form an, activated, supported catalyst more active for conversion of synthesis gas after said step (iii) than after step (i).
