Abstract
The present invention includes Fischer-Tropsch catalysts, reactions using Fischer-Tropsch catalysts, methods of making Fischer-Tropsch catalysts, processes of hydrogenating carbon monoxide, and fuels made using these processes. The invention provides the ability to hydrogenate carbon monoxide with low contact times, good conversion rates and low methane selectivities. In a preferred method, the catalyst is made using a metal foam support.
Claims20
A catalyst structure for Fischer-Tropsch synthesis, comprising:
- a porous structure with a pore surface area and a pore size of at least about 0.1 μm;
- wherein the porous structure comprises a honeycomb, felt, foam or wad;
- a buffer layer disposed on said porous structure;
- a porous interfacial layer with a pore surface area and a pore size less than the pore size of the porous structure, said porous interfacial layer disposed upon said buffer layer;
- a Fischer-Tropsch catalyst selected from the group consisting of cobalt, ruthenium, iron, rhenium, nickel, osmium and combinations thereof placed upon said pore surface area of said porous interfacial layer.
