A Fischer-Tropsch process for producing hydrocarbons, comprising 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, wherein the catalyst comprises at least one catalytically active metal selected from the group consisting of cobalt, iron, nickel and ruthenium and combinations thereof, a catalyst support, and silver. The catalyst may include a promoter. A preferred catalyst comprises cobalt, platinum and/or ruthenium and/or rhenium, and silver supported on a support selected from the group consisting of Al2O3, ZrO2, sulfated ZrO2, WO3—ZrO2, MCM-41, H-Beta, Sylopol SiO2, AlF3, fluorided Al2O3, bentonite, zeolite, TiO2, and SiO2—Al2O3, molecular sieves, and combinations thereof.
A process for producing hydrocarbons, comprising 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, said conversion-promoting conditions including temperatures not greater than about 225° C., wherein the catalyst comprises (a) cobalt, (b) catalyst support, and (c) silver, wherein the catalytic activity of the catalyst is increased by the addition of silver.
A process for producing hydrocarbons, comprising 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, said conversion-promoting conditions including temperatures not greater than about 225° C., wherein the catalyst comprises (a) cobalt, (b) catalyst support, (c) silver, and a promoter selected from the group consisting of rhenium, ruthenium, platinum and combinations thereof, wherein the catalytic activity of the catalyst is increased by the addition of silver.
A method for increasing the activity of a cobalt-containing Fischer-Tropsch catalyst for use in a Fischer-Tropsch reaction at temperatures not greater than 225° C., comprising adding an amount of silver to the catalyst.
