Abstract: The present disclosure relates generally to processes for activating Fischer-Tropsch synthesis catalysts. In particular, the application concerns a process for the activation of a Fischer-Tropsch synthesis catalyst, the process comprising: (i) contacting the catalyst with a first gaseous composition comprising at least 80% N2 at a pressure in the range of 2 barg to 20 barg at a temperature of no more than 150° C.; (ii) contacting the catalyst with a second gaseous composition comprising at least 80% H2 to form a H2/N2 gaseous composition with a H2:N2 molar ratio in the range of 0.2:1 to 2:1, resulting in a pressure in the range of 10 barg to 30 barg; (iii) increasing the temperature to a range of 220° C. to 260° C.; (iv) maintaining the catalyst at the conditions of step (iii) for a hold period in the range of 2 hr to 96 hr.

Abstract: The present invention relates to a process for producing a Fischer-Tropsch synthesis catalyst wherein from 15 to 40 mol. % of the cobalt thereon is in the form of cobalt oxide. The present invention also relates to a start-up process for a reduced-and-passivated cobalt-containing Fischer-Tropsch catalyst, wherein from 15 to 40 mol. % of the cobalt thereon is in the form of cobalt oxide and the reduced-and-passivated catalyst is activated by contacting the catalyst with a syngas stream.
