TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The nickel/alumina catalyst has a structure of formula (NixCeyZrzOx+2(y+z)/Al2O3).Either x = 0.04-0.45; andy = 0.01-0.96; orx+y+z = 1.The Fe-Cu-K/zeolite catalyst comprises 10-70 wt.% of iron, 1-10 wt.% of copper and 1-10 wt.% of potassium, based on the zeolite. The zeolite of the Fe-Cu-K/zeolite catalyst has a specific surface area of 200-500 m2/g and a silicon/aluminum molar ratio of 2-200, and is pre-treated with a single metal precursor of IA, IIA, zirconium, phosphate and lanthanum or bimetal precursors by ion exchange or impregnation method. The Fe-Cu-K/zeolite catalyst further comprises 0-20 wt.% of aluminum, based on the zeolite support. The Fe-Cu-K/zeolite catalyst has a specific surface area of 150-300 m2/g.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The combined reforming is carried out at 600-1000 degrees C, 0.5-30 atmosphere and a space velocity of 1000-500000 h-1. The combined reforming provides a methane conversion of 80-95% and a carbon dioxide conversion of 60-90%. The Fischer-Tropsch reaction is carried out at 250-500 degrees C, 5-60 kg/cm2, and a space velocity of 500-10000. EXAMPLE - Ammonia type ferrierite zeolite was calcined at 600 degrees C to prepare proton type ferrierite zeolite. The resultant proton type ferrierite zeolite (5 g) was mixed with a solution in which iron nitrate hydrate, as iron precursor, copper nitrate, as copper precursor, and potassium carbonate as potassium precursor, were dissolved in deionized water (60 ml), and was agitated for 12 hours to prepare an impregnated catalyst. The impregnated catalyst was dried at 100 degrees C over 12 hours and calcined at 500 degrees C for 5 hours under air atmosphere. Thus prepared catalyst had a composition: 20 wt.% of iron/2 wt.% of copper/4 wt.% and potassium/ferrierite, based on metal weight. Specific surface area of the catalyst was 227 m2/g. Prior to reaction, the prepared catalyst (0.3 g) was packed in a steel fixed bed reactor, and reduced at 450 degrees C for 12 hours under hydrogen (5 vol.% hydrogen (H2)/helium (He)) atmosphere. Reaction was carried out at 300 degrees C, 10 kg/cm2, and a space velocity of 2000 L/kg cat/hr, while supplying reactants at a fixed molar ratio of carbon monoxide: hydrogen : argon (internal standard) was 63.2 : 31.3 : 5.5.
