Partial oxidation of sulfur-containing solid carbonaceous fuel
This patent describes the improvement in a process for the partial oxidation and desulfurization of sulfur and silicate-containing comminuted solid carbonaceous fuel including, basis solid fuel, 0.2 to 6.0 wt. % sulfur and 0.1 to 30 wt. % of silicate compounds including iron silicate. It comprises: introducing into the reaction zone of a free-flow unobstructed vertical down-flowing refractory lined partial oxidation gas generator a feed mixture comprising the solid carbonaceous fuel and supplemental calcium-containing material entrained in a gaseous medium selected from the group consisting of steam, nitrogen, CO{sub 2}, recycle synthesis gas, free-oxygen containing gas, and mixtures thereof; and with or without a temperature moderator.
