The present invention relates to a process for the activation of a catalyst in the presence of a hydrocarbon liquid, which catalyst comprises a Group Ib, VIIb or VIII metal compound, by contacting the catalyst with a hydrogen-containing gas at a hydrogen partial pressure of at least 15 bar abs. The present invention further relates to a hydrocarbon synthesis process which comprises activating a hydrocarbon synthesis catalyst in the presence of a hydrocarbon liquid by contacting the catalyst with a hydrogen-containing gas at a hydrogen partial pressure of at least 15 bar abs., and, subsequently, contacting the catalyst with a mixture of hydrogen and carbon monoxide at hydrocarbon synthesis reaction conditions.

1. A process for the activation of a fresh or rejuvenation of a spent catalyst in the presence of a hydrocarbon liquid, which catalyst is a hydrocarbon synthesis catalyst comprising a Group Ib, VIIb or VIII metal compound, said process comprising contacting a fresh or spent catalyst in a reactor with a hydrogen-containing gas at a hydrogen partial pressure of at least 30 bar abs for a time sufficient to activate or rejuvenate said catalyst, wherein said contact further takes place in the presence of a hydrocarbon liquid, which liquid is selected from a product of a hydrocarbon synthesis process crude oil fractions, liquid polyolefins, or mixtures thereof; and subsequently contacting the catalyst with a mixture of hydrogen and carbon monoxide at hydrocarbon synthesis conditions.
