Abstract
A Fischer-Tropsch catalyst includes a substantially homogeneous blend of cobalt and alumina, wherein the catalyst includes a pore volume (PV) ranging from 0.3 cc/g to 0.5 cc/g and an average pore diameter (PD) ranging from 18 nm to 30 nm. Methods of preparing the Fischer-Tropsch catalyst are also included in the present disclosure.
Claims7
A catalyst, comprising:
- a blended structure including a first cobalt component and an aluminum-containing compound alumina, the first cobalt component and the aluminum-containing compound being substantially uniformly distributed throughout the blended structure;
- and
- a second cobalt component in contact with an outer surface of the blended structure, the second cobalt component added to the outer surface of the blended structure using impregnation;
- wherein a total weight percentage of cobalt in the catalyst ranges from 10 wt. % to 40 wt. % of a total weight of the catalyst and a total weight percentage of alumina ranges from about 50 wt. % to about 90 wt. % of the total weight of the catalyst;
- and wherein the first cobalt component present in the blended structure accounts for 20% to 75% of the total weight percentage of cobalt in the catalyst.
