✦ Synopsis

The production of methane from CO and Hz over an Ni-Al,OB catalyst was studied in a gradientless reactor under steady-state and pure component cycling conditions, at a pressure of 1 atm and a temperature of 513 K. It was observed that the time-averaged production rate of methane increased as the cycle period decreased. The highest rates were obtained for a cycle period of 12 s, the lowest investigated, and at a cycle split of 0.4 which coincides with the composition of the optimum steady-state feed mixture. Time-averaged rates up to 7% higher than the experimentally determined optimum steady-state rate on a mole basis were obtained. To the best of our knowledge this is the first report on concentration forcing of the methanation reaction to appear in the open literature, and the results are encouraging.
