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.
Claims28
A reactor for hydrogenating carbon monoxide comprising:
- a reaction chamber having chamber walls;
- a catalyst comprising a supported Fischer-Tropsch catalytic metal in said reaction chamber;
- wherein said catalyst comprises a monolith which comprises a continuous piece of porous material having contiguous porosity such that reactants and products of a Fischer-Tropsch reaction are able to diffuse through the contiguous porosity of the catalyst;
- at least one cooling chamber in thermal contact with at least one chamber wall of said reaction chamber wherein the at least one chamber wall of said reaction chamber separates the reaction chamber from the at least one cooling chamber;
- wherein said catalyst has a thickness of about 1.5 cm or less;
- and wherein said catalyst is within 0.5 cm of at least one reaction chamber wall.
