Stable slurries of solid carbonaceous fuel and water
This patent describes a pumpable slurry of solid carbonaceous fuel and water with reduced viscosity and sedimentation rate for use as feed to a partial oxidation gas generator for the production of raw synthesis gas, reducing gas, or fuel gas by reacting in the gas generator with a free-oxygen containing gas. The slurry comprises about 50 to 75 weight percent of high rank comminuted solid carbonaceous fuel having 5.0 weight percent or below of organically combined oxygen wherein the solid carbonaceous fuel is selected from the group consisting of anthracite coal, petroleum coke, coal liquefaction solid residue, asphaltic bitumen, and mixtures thereof; and about 0.001 to 0.100 parts by weight of a surfactant for each part by weight of the solid carbonaceous fuel.
