Title: Process for the production of rich combustible gas
IPC: C10J1/207
Filed: 1928-12-24
Abstract: 304,760. Metallges. Akt.-Ges. Jan. 26, 1928, [Convention date]. Producers.-A process for the production of a rich gas from bituminous fuel, comprises distill- ' ing the fuel and gasifying the residue with a gas mixture containing oxygen and such a high proportion of steam that most of the carbon in the fuel is transformed to carbon dioxide and the hydrogen content of the resulting gas exceeds the carbon monoxide content. The undecomposed steam in the gas is used for generating fresh steam for the gasification process; this can be done either by spraying the oxygen with the hot water used for cooling the rich gas, or by generating steam from this cooling water in a vacuum apparatus, this steam being superheated by the semi-coke. Carbon dioxide is removed from the gas before use. In an example, semi-coke is treated by a mixture containing 5 per cent oxygen and 95 per cent steam and a decomposition temperature of 600‹ to 1000‹ C. is maintained.
