A continuous process for producing a gas Stream comprising mainly gas selected from the group consisting of H2, co, CO2, H2O, H2S, cos, CH, N2 and their mixtures.

摘要

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.
