Abstract:
1. A process for hydrogenating carbon monoxide to form a Fischer-Tropsch hydrocarbon product, the process comprising: providing a catalyst comprising iron, copper and potassium, wherein the weight ratio of iron to copper is in the range of from about 100:0.2 to about 100:2 and the weight ratio of iron to potassium is in the range of from about 100:0.5 to about 100:1.5, and wherein the iron in the catalyst comprises a maghemite:hematite weight ratio in the range of about 1%:99% to about 70%:30%; activating the catalyst by exposure to a gas comprising carbon monoxide, hydrogen, or a combination thereof for a selected period of time at selected levels of pressure, temperature, and space velocity, to produce an activated catalyst; and contacting a synthesis gas stream with the activated catalyst in a Fischer-Tropsch slurry-bed reactor whereby a Fischer-Tropsch hydrocarbon product is obtained.
