摘要： The present invention relates to a process for conveniently preparing a supported cobalt-containing Fischer-Tropsch synthesis catalyst having improved activity and selectivity for C5+ hydrocarbons. In one aspect, the present invention provides a process for preparing a supported cobalt-containing Fischer-Tropsch synthesis catalyst, said process comprising the steps of: (a) impregnating a support material with: i) a cobalt-containing compound and ii) acetic acid, or a manganese salt of acetic acid, in a single impregnation step to form an impregnated support material; and (b) drying and calcining the impregnated support material; wherein the support material impregnated in step (a) has not previously been modified with a source of metal other than cobalt; and wherein when the cobalt-containing compound is cobalt hydroxide, a manganese salt of acetic acid is not used in step (a) of the process.

摘要： A process for the conversion of a feed comprising a mixture of hydrogen and carbon monoxide to hydrocarbons, the hydrogen and carbon monoxide in the feed being present in a ratio of from 1:9 to 9:1 by volume, the process comprising the steps of: pre-treating a catalyst composition comprising titanium dioxide support and oxidic cobalt or a cobalt compound decomposable thereto, for a period of from 1 to 50 hours, with a hydrogen gas-containing stream comprising less than 10% carbon monoxide gas by volume of carbon monoxide gas and hydrogen gas, to form a reductively-activated catalyst; and contacting the feed at elevated temperature and atmospheric or elevated pressure with the reductively-activated catalyst; wherein the step of pre-treating the catalyst composition is conducted within a temperature range of from 200° C. to less than 300° C., preferably from 220° C. to 280° C., more preferably from 250° C. to 270° C.
