Selective synthesis of liquid hydrocarbons from carbon dioxide and methane

Abstract 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 CO 2 and Fischer-Tropsch reaction. A nickel supported magnesia catalyst gave the equilibrium conversion of CH 4 and CO 2 above 850 °C. On a Co-La/SiO 2 catalyst the CO conversion was 20 % at 250 °C and 0.7 MPa and the selectivity to C5+ hydrocarbon was 70%. The major by-product in the second reactor was CH 4 , which can be recycled into the first reforming reactor.
