Pox process with high temperature desulfurization of syngas
This patent describes a continuous process for the production of desulfurized synthesis gas, fuel gas, or reducing gas comprising: (1) reacting sulfur-containing heavy liquid hydrocarbonaceous fuel and/or sulfur-containing solid carbonaceous fuel by partial oxidation with as free-oxygen containing gas and in the presence of a temperature moderator in the free-flow refractory lined reaction zone of a gas generator at an autogenous temperature in the range of about 1900F, to 2900F, and above the ash-fusion temperature of the slag formed in the reaction zone, and a pressure in the range of about 2 to 250 atmosphere to produce a hot stream of synthesis gas, reducing gas, or fuel gas comprising H/sub 2/, CO, CO/sub 2/, H/sub 2/S, COS and at least one gaseous material selected from the group consisting of H/sub 2/O, N/sub 2/, CH/sub 4/, NH/sub 3/, A, and containing entrained material comprising particulate carbon, and slag; (2) passing at least a portion of the hot gas stream from (1) in admixture with an iron-containing additive through an unobstructed central passage of a radiant cooler; where in the radiant cooler the weight ratio of iron-containing additive to sulfur plus the ash in the fuel feed is in the range of about 0.5 to 10.0 to 1.0, and wherein the iron-containing additive is introduced into the hot gas stream from (1) at the entrance to and/or at one or more locations within the radiant cooler.
