The kinetics of the carbon monoxide conversion with steam on a Czechoslovak FeCr catalyst was investigated. The experimental data were obtained on a gradient-free differential reactor with recirculating gaseous phase at temperatures of 633 and 693 K and pressures from the range 0.1-0.9 MPa. The evaluation of experimental data showed that the reaction rate increases with increasing pressure according to a downward convex and that it also increases with increasing content of carbon monoxide in the gas and with decreasing content of carbon dioxide. The reaction kinetics was described by an equation derived from the Langmuir-Hinshelwood concept for the case when the limiting step of the reaction is a surface reaction.

Kinetics of CO methanation on a commercial Ni/SiO2 catalyst was evaluated at atmospheric pressure, between 528 and 550 K and for hydrogen to carbon monoxide molar ratios ranging from 3 : 1 to 200 : 1. The effect of reaction products on the reaction rate was also examined. Below 550 K, only methane was selectively formed. Above this temperature, the formation of carbon dioxide was also observed. The experimental data could be described by two modified Langmuir-Hinshelwood kinetic models, based on hydrogenation of surface CO by molecularly or by dissociatively adsorbed hydrogen in the rate-determining step. Water reversibly lowered catalyst activity and its effect was more pronounced at higher temperature.
