Title: Partial oxidation process with second stage addition of iron containing additive

Abstract

This patent describes a continuous process for the production of desulfurized synthesis gas, fuel gas, or reducing gas comprising: (1) reacting a first portion of sulfur-containing heavy liquid hydrocarbonaceous fuel and/or sulfur-containing solid carbonaceous fuel by partial oxidation with a free-oxygen containing gas and in the presence of a temperature moderator in a first free-flow refractory lined reaction zone of a gas generator at an autogenous temperature in the range of about 1900F, to 2900F, and a pressure in the range of about 2 to 250 atmospheres to produce a hot stream of synthesis gas, reducing gas, or fuel gas comprising H/sub 2/, C, 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, unreacted fuel if any, and slag; (2) passing at least a portion of the hot gas stream from 91) in admixture with a second portion of the fuel and an iron-containing additive through a second unobstructed free-flow refractory lined reaction zone wherein sufficient iron-containing additive is introduced into the second reaction zone so as to provide iron atoms in the amount of aboutmore » 1.1 to 1.8 times the atoms of sulfur in the second reaction zone plus about 0.3 to 1.2 times the atoms of silicon in the ash in the second reaction zone, and the mole ratio of H/sub 2/O and/or CO/sub 2/ to carbon in the second reaction zone is in the range of about 0.7 to 25.« less
