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.
