摘要
The synthesis of liquid hydrocarbons from carbon dioxide and methane was studied under pressurized conditions using two stage reactor process composed of methane reforming by CO2 and Fischer-Tropsch reaction. A nickel supported magnesia catalyst gave the equilibrium conversion of CH4 and CO2 above 850-degrees-C. On a Co-La/SiO2 catalyst the CO conversion was 20 % at 250-degrees-C and 0.7 MPa and the selectivity to C5+ hydrocarbon was 70%. The major by-product in the second reactor was CH4, which can be recycled into the first reforming reactor.
