A process for conversion of hydrogen and carbon monoxide into hydrocarbons in the presence of an ebullient bed of catalyst comprising reduced iron oxide containing an amount of potassium equivalent to 2 to 10 pounds potassium carbonate per 1000 pounds iron oxide catalyst, and having an average particle size in the range of 100-1000 microns. The catalyst may be sulfided for increasing the yield of C1-C4 range hydrocarbons.

A process for producing from synthesis gas a stream of light hydrocarbon gases containing an increased yield of C1-C4 range saturated hydrocarbons comprising: (1) reacting hydrocarbons or carbonaceous charge stocks ranging from methane through coal or coke by partial oxidation with a free oxygen-containing gas and H2O at an autogenous temperature in the range of about 1600°F. to 3000°F. and a pressure in the range of about 1 to 250 atmospheres in the reaction zone of a noncatalytic synthesis gas generator to produce an effluent gas mixture; (2) purifying the effluent gas stream from (1), thereby producing a feed gas stream substantially comprising hydrogen and carbon monoxide, and with or without H2S, CO2, H2O and COS; (3) passing said feed gas stream upward through an ebullient bed of particulate conversion catalyst in a reaction zone at a temperature in the range of about 600°to 1000°F., a pressure in the range of about 200 to 3000 psig, a H2+CO space velocity in the range of about 250 to 2500 v/hr/v, a superficial gas velocity in the range of about 1 to 10 ft./sec., and a H2/CO mole ratio in the range of at least 1:1 to about 3:1; and wherein said conversion catalyst consists essentially of iron oxide selected from the group consisting of mill scale, magnetite, and mixtures thereof, ground to a particle size in the range of about 350 to 800 microns, magnetically separated from extraneous matter, treated with an aqueous solution of potassium carbonate in an amount sufficient to deposit upon said ground iron oxide about 2-10 pounds potassium carbonate per 1000 pounds iron oxide, dried, chemically reduced with hydrogen at a temperature in the range of about 650°-800°F. and a pressure in the range of about 100 to 1000 psig until evolution of water ceases, and subsequently sulfided at an elevated temperature in the range of about 200°-900°F. with a sulfur-containing compound capable of sulfiding said catalyst such that said reduced iron catalyst contains from about 0.01 to about 0.1 weight percent sulfur; (4) cooling the effluent gas from the reaction zone to condense out a liquid phase comprising normally liquid hydrocarbons, organic chemicals, and water; and (5) separating a gas phase comprising light hydrocarbons containing an increased yield of C1 to C4 range saturated hydrocarbons, H2, CO, H2O and CO2.
