        To determine the role of secondary reactions in the process of conversion of water gas on Fe catalysts, comparative experiments were conducted on often used precipitated ferric aluminum catalyst and on the crude Fe, both activated with K2CO3.  The oxide catalyst, after being reduced to metallic iron by the H2, is oxidized again by water gas.  C obtained by the decomposition of CO on oxide contact can be changed into gas again by water gas, beginning around 500°.  The influence of H2S poisoning on the activity of precipitated oxide catalyst was observed also.
