Abstract
This invention provides a process for producing hydrocarbons. The process involves contacting a feed stream comprising hydrogen and carbon monoxide with a catalyst in a reaction zone maintained at conversion-promoting conditions effective to produce an effluent stream comprising hydrocarbons, and uses a catalyst including (a) at least one catalytic metal for Fischer-Tropsch reactions (e.g., iron, cobalt, nickel and/or ruthenium) and (b) a non-layered mesoporous support which exhibits an X-ray diffraction after calcination that has at least one peak at a d-spacing of greater than 18 Ångstrom units.

A method for preparing a Fischer-Tropsch catalyst comprising impregnating a, support with a salt of a catalytically active metal selected from the group consisting of iron, cobalt, nickel, ruthenium, and combinations thereof and a promoter, wherein the support comprises a non-layered mesoporous support that exhibits an X-ray diffraction pattern after calcination that has at least one peak at a d-spacing of greater than 18 Ångstrom units, drying the impregnated support, and reducing the impregnated support with a hydrogen-containing stream.
A method for preparing a Fischer-Tropsch catalyst comprising impregnating a support with a salt of a catalytically active metal selected from the group consisting of iron, cobalt, nickel, ruthenium, and combinations thereof and a promoter, wherein the support comprises a non-layered mesoporous support that exhibits an X-ray diffraction pattern after calcination that has at least one peak at a d-spacing of greater than 18 Ångstrom units, and drying the impregnated support, wherein the support is impregnated with a solution of zero valent cobalt in an organic solvent.
