                  In a mixture of CO, H2, and H2O, roughly 1:1:1, 2 reactions occur in the presence of Ni catalysts:  (1) 2CO+2H2→CH4+CO2.  (2) CO+H2O→CO2+H2.  The influence of KOH, NaOH, and NH4OH, used to precipitate Ni, was small.  Alumina promotes reaction (1); its maximum activity occurs at a concentration below 0.16%.  Addition of K2CO3 to the catalyst promotes reaction (2).  Results of 11 runs are tabulated, with analyses of reactants and resultants, weight and volume of catalyst, rate of flow and total volume of gases, and reaction temperatures.
