[54] CATALYST TREATMENT
[57] Abstract: A method of preparing a non-pyrophoric F-T catalyst for handling, storage, transport and deployment, which comprises the steps of: impregnating a porous support material with a source of cobalt as a catalytically active material; calcining the impregnated catalyst; activating the catalyst by treating the impregnated support material with a reducing gas at a temperature up to 600˚C; and passivating the activated catalyst. The passivated catalyst can be transported and stored before being re-activated. Re-activation can be effected before loading into a reactor or in situ in the reactor.
