The conversion of methane for H2 production over a CoMo catalyst with several Co loadings carbided at various temperatures using two carbiding methods of different heating rates was studied. The effects of the CO2 addition and H2 pretreatment on the catalyst lifetime were determined. The low-temperature carbiding increased the surface area of the catalysts and produced CoMo oxycarbides decorated with pyrolytic carbons, from which hydrogen and graphite carbons were produced during the CH4 reaction. The high-temperature carbiding produced CoMo carbides. The CoMo oxycarbides had the structure of β-Mo2C with Co metal.
