Prodn of combustible gases, esp for turbines - by partial combustion of liq. hydrocarbons followed by treatment with liq. hydrocarbon and steam

摘要

Combustible gases, esp. for gas turbines, are produced by (a) subjecting the liq. hydrocarbon (esp. boiling in the naphtha range), opt. in the presence of steam, to partial combustion with a gas with a low O2 content (e.g. air) at a manometric press. of 2.1-207 (pref. 13.8-34.4) bar and an autogenic temp. of 871-1649 degrees C to produce an effluent gas contg. N2, Co and H2; (B) injecting a liq. hydrocarbon and steam into the effluent gas at the same pressure as in (a), to cool the effluent gas and heat the steam/hydrocarbon mixt to 538-982 degrees C, so that at least part of the hydrocarbon is converted into CH4; (c) cooling the prod. to condense H2O; and (d) recovering a prod. consisting of CO, N2, H2 and CH4. Prods. with a calorific value of 1.33-8.89 kcal/1 can be obtd.
