| Abstract: | An experimental study of the catalytic action of molybdenum in the reactions of methane with water vapor and carbon dioxide was performed in a fluidized bed differential reactor. In the experiments, special care was taken to isolate the homogeneous reactions which could have interfered with the catalytic effect. The ratio O2/CH4 in the feed and the heterogeneous reactions of oxidation and carbide Mo2C formation, were shown to have considerable influence on the obtained yields. From kinetic results obtained on carbide and pure metal, a reaction mechanism is proposed, and a rate equation is presented for the conversion of methane by water vapor on molybdenum. |
