摘要: The conversion of CH4 and CO2 to synthesis gas (H2 + CO) higher hydrocarbons was investigated over BaTiO3, glass, Ni/SiO2, NiFe/SiO2, a mixture Ni/SiO2 BaTiO3 in dielectric-barrier discharges (DBDs) at low temperatures ambient pressure. fresh spent catalyst samples were characterized by SEM, XRD, BET TEM. variation the permittivity packing materials with same size did not influence reaction significantly. Exposing one metal electrode plasma could enhance selectivity CO reaction. decreased sequence > NiFe/SiO2 Ni/SiO2. A increased H2, both catalysts enhanced mechanism assisted proposed. Specific input energy (SIE) an important factor affecting reaction, it possible alter product optimizing residence time certain SIE catalyst.
