Abstract
This invention relates to the field of Fischer-Tropsch catalysis, in particular to activation of a Fischer-Tropsch catalyst. More particularly the invention relates to a method of activating an iron based Fischer-Tropsch catalyst which includes iron in a positive oxidation state by contacting in a reactor said iron based catalyst with a reducing gas selected from the group consisting of CO and a combination of Hand CO; at a temperature of at least 245° C. and below 280° C.; at a reducing gas pressure of above 0.5 MPa and not more than 2.2 MPa; and at a GHSV of total gas fed to the reactor of at least 6000 ml(N)/g cat/h, thereby reducing the iron that is in a positive oxidation step in the catalyst.
