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.
Claims20
A method for preparing a catalyst, comprising:
- forming a mixture using a first precursor, a second precursor, and a liquid, wherein the first precursor includes cobalt, and wherein the second precursor includes an aluminum-containing compound;
- shaping the mixture to form a structure;
- optionally drying the structure;
- calcining the structure to form a catalyst;
- optionally adding one or more metals to the catalyst, wherein the one or more metals include cobalt;
- and
- optionally reducing the catalyst.

A method for preparing a catalyst, comprising:
- forming a mixture using a first cobalt salt, a silver salt, and an aluminum-containing compound;
- shaping the mixture to form a structure;
- optionally drying the structure;
- heating the structure at a temperature ranging from 120° C. and 725° C. to form a cobalt oxide containing structure;
- adding a second cobalt salt to the cobalt oxide containing structure using impregnation to form an impregnated structure;
- heating the impregnated structure at temperature ranging from 120° C. and 725° C. to form a catalyst, wherein between 20 wt. % to 75 wt. % of cobalt in the catalyst is present from the mixture;
- and
- optionally reducing the catalyst.
5 more elements
A catalyst, comprising:
- a blended structure including a first cobalt component and an aluminum-containing compound, 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 wherein the first cobalt component present in the blended structure accounts at least 25% of the total weight percentage of cobalt in the catalyst.
