1. A method of preparing a Fischer-Tropsch catalyst for handling, storage, transport and deployment, the method comprising the steps of:
impregnating an initial support material comprising alumina with a source of a divalent metal capable of forming a spinel phase with alumina to form a porous support material having a spinel phase; drying the porous support material; calcining the porous support material at a temperature reaching at least 1000° C.; impregnating the porous support material with a source of cobalt as a catalytically active material to produce an impregnated support material; calcining the impregnated support material to produce a calcined impregnated support material; activating the calcined impregnated support material with a reducing gas comprising hydrogen at a temperature up to 500° C. to reduce a substantial portion of the cobalt present to the metal to produce an activated catalyst; and passivating the activated catalyst with an oxidizing gas for a period of time sufficient to create a protective layer of oxide on the surface of the catalyst to produce a passivated catalyst. |
