Abstract
528,338. Gas manufacture. GAS ENGINEERS, INSTITUTION OF, DENT, F. J., and APPLETON, E. V. May 4,1939, No. 13350. CClass 55 (i)] A gas suitable for use as town gas is obtained by the gasification of weakly caking bituminous coal or coke by the action of oxygen and steam under pressure, with a high rate of gasification, to produce a gas consisting mainly of hydrogen and carbon-monoxide which are caused to react and form methane whilst the gases are still under pressure, the heat evolved by this reaction being used to preheat steam under pressure for use in the gasification. Pressures in the generator of 10 and 15 atmospheres are referred to in examples. The gas from the generator 1 passes through a cooler 2 to separate steam and tar, a washer 3 for absorbing carbon dioxide and hydrogen sulphide, and a purifier 4 for removing residual hydrogen sulphide. The purified gas passes through a reaction chamber 6 forming part of a heat exchanger 7 and containing a catalyst for this methane reaction, and the gas then passes through a washer 9 for removal of carbon dioxide, and passes by a pipe 10 to storage. Part of the generator may be byepassed through pipe 11 direct to the outlet, and part of the gas from pipe 8 may be re-circulated through the reaction chamber by pump 14. Steam from pipe 15 and oxygen from pipe 17 pass through the heat exchanger, but unheated oxygen may be supplied through pipe 16. In an example, the steam and oxygen supplied at a temperature of 300 ‹C. to the heat exchanger were further heated to 900‹C. in the latter. The concentration of carbon monoxide supplied to the reaction chamber can be controlled by the relative proportions of steam and oxygen supplied to the generator, and for further control some of the carbon monoxide may be caused to react with steam in the presence of a catalyst to produce hydrogen. Both the reaction chamber 6 and the heat exchanger 7 may be charged with the catalyst, and the steam and oxygen passed through these alternately with the generator gas in order to regenerate the exhausted catalyst. Specifications 364,407, 380,158 and 392,427 are referred to.
