1579b. IPATIEFF, V. N., MONROE, G. S., AND FISCHER, L. E. Low-Temperature Hydrogen Production. Ind. Eng. Chem., vol. 42, 1950, pp. 92-94; Chem. Abs., vol. 44, 1950, p. 3,221.
Experiments were conducted on the direct catalytic conversion of CH4 and H2O to H2 and CO2 at about 500°-800° and at atm. and at 250 p.s.i. pressure. Space velocities of CH4 of about 120 per hr. and mole ratios of H2O:CH4 of about 5 at atm. pressure and 32 at high pressure were used. The most effective catalysts were NiO or NiO and CuO on kieselguhr and the optimum concentrations about 7% CuO, 70% NiO, and 23% kieselguhr. This gave 55-92% conversion of CH4. Increase of temperature increased H2 yield and formation of CO. Increase of pressure decreased CO formation and H2 yield, but the latter effect was nullified by increasing the H2O:CH4 mole ratio.
