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.
Claims22
A method for preparing a Fischer-Tropsch catalyst, the method comprising:
- forming a mixture using a cobalt salt, a liquid, and boehmite;
- shaping the mixture subsequent to forming the mixture, sufficient to form a structure;
- drying the structure to form a dried structure;
- calcining the dried structure sufficient to form a catalyst;
- optionally adding one or more metals to the catalyst by impregnation, wherein the one or more metals include cobalt;
- and
- optionally reducing the catalyst.

A method for preparing a Fischer-Tropsch catalyst, the method comprising:
- mixing a first precursor and a second precursor sufficient to form a paste, wherein the first precursor includes a solution including at least cobalt nitrate and silver nitrate, and wherein the second precursor includes boehmite;
- extruding the paste sufficient to form a structure;
- calcining the structure sufficient to form a catalyst;
- optionally adding one or more metals to the catalyst by impregnation, wherein the one or more metals include cobalt;
- and
- optionally reducing the catalyst.
