Dry reforming of methane reaction for hydrogen and syngas production using cobalt catalysts and nickel-cobalt bimetallic catalysts

Abstract

The cobalt catalysts (cobalt content by weight: 7%, 10% and 15%) and cobalt-nickel bimetallic catalysts (cobalt-nickel content by weight: 3.5%-3.5%, 5%-5% and 7%-7%) were studied in dry reforming of methane for hydrogen and syngas production. All catalysts were synthesized by the wetness impregnation method. The dry reforming of methane was carried out at 700oC, atmosphere pressure using a mixture; CH4 and CO2 in ratio 1:1. The result showed that the good activity and stability depend on metal content in catalysts and the combined 2 metals as bimetallic catalysts. The optimum amounts of catalysts are 10wt% Co for mono-metallic catalysts, 75%CH4 and 75%CO2 conversion and 7wt% Ni-7wt% Co for bimetallic catalysts, 87%CH4 and 89%CO2 conversion.
