Abstract:
1. A catalyst comprising: a porous metallic support, the porous metallic support having a first surface and a first pore size of at least 0.1 μm; a porous interfacial layer, the porous interfacial layer disposed on the first surface and having a second pore size that is less than the first pore size; and a Fischer-Tropsch catalytic metal; wherein the catalyst possesses catalytic activity such that, if the catalyst is placed in a tube inside an isothermal furnace and exposed to a feed stream consisting of a 3 to 1 ratio of hydrogen gas to carbon monoxide, at 250° C. and an average residence time of 12.5 seconds, the selectivity to methane is greater and the conversion of carbon monoxide is lower at 24 atmospheres than it is at 6 atmospheres of pressure.
