466. CHAKRAVARTY, K. M., AND SARKER, J. M. Catalytic Formation of CH4 From CO and H2 – a Study of Ni and Ni- Alumina Catalysts Prepared From the Hydroxide, Using KOH, NaOH and NH4OH as Precipitants. Current Sci., vol. 13, 1944, p. 127; Chem. Abs., vol. 38, 1944, p. 6178. 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. |
