A catalyst for the Fischer-Tropsch process, consisting essentially of cobalt oxide supported on an inert carrier consisting essentially of alumina, wherein the cobalt oxide consisting essentially of crystals having an average size ranging from 20 to 80 Å.
A process for preparing a catalyst consisting essentially of cobalt oxide supported on alumina, wherein the cobalt oxide consisting essentially of crystals having an average size ranging from 20 to 80 Å, which comprises the following steps:
- 1) preparing an intermediate, supported on alumina, having general formula (I)
- [Co2+1−xAl+3x(OH)2]x+[An−x/n].mH2O (I)
- wherein x ranges from 0.2 to 0.4, A is an anion, x/n is the number of anions necessary for neutralizing the positive charge, m ranges from 0 to 6;
- 2) calcining the intermediate having general formula (I) with the formation of crystalline cobalt oxide.
