                    Reaction CO+H₂O=CO₂+H₂+9.6 kcal. was studied in the presence of K₂CO₃ on activated C and on technical Fe oxide catalyst of the type known as nitrogene.  Data are reported on the effects of the space velocity, total pressure, and partial pressures of the components, and the kinetics and the mechanism of the process are discussed.  The surface of the catalyst was determine by the method of Gaukhman and Roĭter (abs. 1164).  the results are explained by a new theory for the K carbon catalyst in which the following scheme of reactions is proposed:  2KOH+CO=K₂CO₃+H₂; K₂CO₃+H₂O=2KOH+CO₂, with summary result; CO+H₂O=H₂+CO₂.  In case of the Fe catalysts there is evidence for considerable effect of the following reaction sequence:  2CO=CO₂+C; C+2H₂O=CO₂+2H₂.
