<p>PCT No. PCT/DE79/00092 Sec. 371 Date Apr. 29, 1980 Sec. 102(e) Date Apr. 29, 1980 PCT Filed Aug. 21, 1979 PCT Pub. No. WO80/00441 PCT Pub. Date Mar. 20, 1980. Method for generating methane or synthesis gas from carbon-containing materials, e.g. coal, by reacting part of the carbon with hydrogen in a hydrogenating gasifier to produce a methane containing gas, and reacting the residual carbon with steam in a steam gasifier to produce a raw gas containing synthesis gas. Features are: (a) The steam gasifier is heated with the raw gas leaving the hydrogenating gasifier. (b) The hydrogen gas entering the hydrogenating gasifier is heated with the raw gas leaving the steam gasifier. (c) The output stage of the steam gasifier is heated electrically. (d) The entire nuclear heat is given off to a steam loop. In addition a methane cracking furnace may be provided with the following features: (a) The methane cracking furnace is heated electrically in the upper temperature range.</p> |
