        Solid, noncaking fuel (brown coal, lean bituminous coal, gas coke) in a 2-25 mm. size is gasified in a refractory-lined, water-jacketed reaction vessel by a mixture of superheated steam and O2 at 20-30 atm.  The gas after cooling is washed with oil and then with H2O, which removes most of the CO2 and H2S.  Residual H2S is removed by Fe2O3, and the purified gas is delivered at 20-25 atm. to high-pressure mains.  The gas has a gross calorific value of 4,000-4,500 kcal. per m.3, depending on the reactivityof the solid fuel.  That from a brown coal contained CO2, 3.0; CnHm, 0.5; O2, 0.1; CO, 22.8; H2, 48.7; CH4, 22.6; N2, etc., 2.3%; the total S was 0.1 gm. per 100 m.3, and NO was 0.052 cc. per m.3  The consumption of O2 is approximately 0.18 m.3 and that of steam 1.25 kg. per m.3 of purified gas.  Production cost is competitive with that of other gasification processes.
