The partial oxidation of methane to produce methanol was investigated with various oxide catalysts. The reaction was carried out with a pyrex lined fixed bed reactor at 450∼480℃ and 20∼46 bar, changing the flow rate and feed gas ratio. The adsorption and desorption characteristics of oxygen were examined with the O2-TPD experiment. Among the catalysts used, the Bi-Cs-Mg-Cu-Mo catalyst was suitable for methanol synthesis, with which the methane conversion and methanol selectivity were about 4% and 22%, respectively. It would appear that a catalyst providing lattice oxygen easily is suitable for methanol synthesis. The methane conversion and methanol selectivity were increased with temperature. The methane conversion was increased with oxygen concentration and the methanol selectivity was decreased with oxygen concentration. The feed flow rate had no significant effects on methane conversion and methanol selectivity. |
