(Japan), vol. 43, 1940, suppl., pp. 116-117; Chem. Abs., vol. 34, 1940, p. 5627. Mixtures containing CO and H2 in ratio of approximately 1:2 were prepared by alternately passing, at a rate of 3 m.3 per hr., CH4-air mixtures, which burn to produce a temperature of 1,380°, and CH4, which absorbs heat on cracking and lowers the temperature to 1,220°, through a Ni-Cr alloy tube containing a Ni catalyst (exact composition not given) and ignited Fe balls made of equal amounts of Fe2O3 and MgO. The exit gas from a typical run had the following composition: CO2, 3.5; O2, 0.9; CO, 21.8; H2, 56.5; CH4, 16.3; and N2, 1.0%. The amount of conversion was increased by putting Ni-kaolin balls above the Fe balls in the tube. In a typical run with this latter arrangement, the exit gas contained CO2, 8.7; O2, 0.9; CO, 27.4; H2, 56.7; CH4, 3.6; and N2, 2.7%. Gives diagram of the apparatus and tabulates results. It is stated that the process could be used industrially. OGDEN, G. See abs. 3341. |
