Popis:	In continuation of previous investigations on the kinetics of CO conversion with water over a commercial iron oxide-chromium oxide catalyst the present article deals with a comparison of the kinetic expressions obtained with laboratory-prepared catalysts without and with alkali present in minor quantities. Quite substantial influences of the alkali on the kinetic expression were found. It was further found that CO 2 concentrations above a certain limit produced a relatively slow decrease of activity of the alkali-impregnated catalysts, the effect being dependent on the temperature of drying of the catalyst prior to the impregnation. Some points of theoretical interest in connection with the findings are discussed.
