This is an improved continuous partial oxidation process for producing synthesis gas or fuel gas from gaseous CO2-solid carbonaceous fuel feeds. A solid carbonaceous fuel such as finely ground coal from a pressurized lock hopper is passed directly into a high pressure high velocity CO2-rich gas stream which carries the particles of coal into a free-flow noncatalytic gas generator where by the partial oxidation reaction with a free-oxygen containing gas, preferably in the absence of supplemental H2O other than that normally present in the reactants, gaseous mixtures principally comprising H2, CO, CO2, and H2O are produced. A CO2-rich gas stream is recovered downstream in the process and recycled to the pressurized feed system. The CO2-rich stream serves as a carrier for the carbonaceous fuel and as a reactant in the reaction zone. |
