Abstract
To prepare a Fischer-Tropsch catalyst, a slurry comprising a particular alumina carrier, water and an active component selected from the group consisting in cobalt (Co), iron (Fe) and mixtures thereof, is subjected to a sub-atmospheric pressure environment. The alumina carrier is thereby impregnated by the active component. The impregnated carrier is dried under a sub-atmospheric pressure environment. The dried impregnated carrier is calcined, thereby to obtain the Fischer-Tropsch catalyst.
