Bituminous coal, 2- to 10-mesh, is charged to a gasifier operated at 350 p.s.i. along with steam at 1,000º F. 7.7 vol., and O₂ of 95% purity 1 vol. The gaseous effluent is withdrawn, tar, oil, H₂O, and CO₂ at 2,300º F. and 575 p.s.i. The effluent from the re-former is contacted with Cr₂O₃-MgO-Fe oxide catalyst at 800º and 560 p.s.i. in a shift converter, the effluent is scrubbed with Et₂NH solution at 530 p.s.i. and atmospheric pressure, then passed over a bed of spongy Fe oxide at 770º F. and 550 p.s.i. The product has a composition of H₂, 62.8%; CO, 30.00%; CO₂, 0.5%; N₂, 6.5%; and H₂O, 0.2%. It is converted to hydrocarbons, oxygenated compounds, in contact with a fluidized Fe catalyst at 600º F. and 500 p.s.i. H₂O, hydrocarbons, and oxygenated compounds are condensed, gaseous hydrocarbons are absorbed in mineral seal oil, 20% of the dry gas is vented to a fuel system to prevent accumulation of N₂, and the remaining gas, after removal of CO₂, is passed to the re-former.
