Abstract: A process for the simultaneous partial oxidation and desulfurization of sulfur and silicate-containing solid carbonaceous fuel for the production of gaseous mixtures comprising H.sub.2 and CO and containing less than about 0.05 volume % of H.sub.2 S and COS. In the process, the solid carbonaceous fuel and a calcium-containing compound are reacted by partial oxidation in the reaction zone of a free-flow unobstructed gas generator with a controlled amount of free-oxygen containing gas and a temperature moderator so that an equilibrium oxygen concentration is provided in the gas phase in the reaction zone having a partial pressure which is less than about 10.sup.-12 atmospheres. The total moles of calcium in the reaction zone is at least equal to about 1.0 times the moles of sulfur in the solid carbonaceous fuel. The partial oxidation and desulfurization reactions take place simultaneously at a temperature which is about 10.degree. to 200.degree. F. below the softening temperature of the ash in the solid carbonaceous fuel and below about 2000.degree. F. at an increased gasification efficiency. The sulfur in the solid carbonaceous fuel in the reaction zone is converted into calcium sulfide particulate matter which leaves the reaction zone along with the fly-ash entrained in the hot raw effluent gas stream.

Abstract: A process for the simultaneous partial oxidation and desulfurization of an ash-containing solid carbonaceous fuel comprising (basis solid fuel) 0.2 to 6.0 wt. % sulfur and 0.1 to 30 wt. % of silicate compounds for the production of gaseous mixtures comprising H.sub.2 and CO and entrained molten slag. In the process, the solid carbonaceous fuel and first and second types of supplemental calcium-containing materials are reacted by partial oxidation in the reaction zone of a free-flow unobstructed down-flowing vertical refractory lined gas generator with a controlled amount of free-oxygen containing gas and a temperature moderator so that an equilibrium oxygen concentration is provided in the gas phase in the reaction zone having a partial pressure which is less than about 10.sup.-9 atmospheres. The partial oxidation and desulfurization reactions take place simultaneously at a temperature above about 1900.degree. F. and about 10.degree. to 100.degree. F. above the fluid temperature of the slag at an increased thermal efficiency. The sulfur in the solid carbonaceous fuel in the reaction zone is converted into calcium and iron sulfide particulate matter which leaves the reaction zone along with the silicates of calcium and iron in the molten ash that is entrained in the hot raw effluent gas stream. Additional desulfurization in a fluidized bed containing calcium-containing material in admixture with carbon-containing material may be used to reduce the amount of H.sub.2 S and COS in the effluent gas stream to less than about 0.05 volume %.

Abstract: The hot effluent gas stream comprising H.sub.2 +CO and entrained molten slag from the partial oxidation of an ash-containing heavy liquid hydrocarbonaceous fuel, an ash-containing solid carbonaceous fuel, or mixtures thereof is passed in succession through a radiant or quench cooling zone, a metal gas transfer line and a convective cooling zone. By covering the metal surfaces of the gas transfer line or the gas transfer line and the convective cooler connected thereto with a high temperature resistant carbon-containing material, substantially no molten slag sticks to the metal heat transfer surfaces on the inside of the gas transfer line or to the surfaces of the gas transfer line and the convective cooler connected thereto which are contacted by the partially cooled gas stream leaving the radiant or quench cooling zones.

Abstract: Synthesis gas is produced by the partial oxidation of a feedstock comprising petroleum coke and/or heavy liquid hydrocarbonaceous fuel containing sulfur and having an ash that contains nickel, vanadium and a low content of silicon. An iron-containing additive is introduced into the vertical free-flow unobstructed refractory lined reaction zone along with the feed to produce first and second types of liquid phase washing agents which collect and transport at least a portion of the vanadium-containing oxide laths and spinels and other ash components out of the reaction zone. The refractory lining of the reaction zone comprises in wt. %: MgO 85 to 98, Fe.sub.2 O.sub.3 0.03 to 3.0, Al.sub.2 O.sub.3 0.02 to 2.0, CaO 0.01 to 10, and SiO.sub.2 0.02 to 2.0. Elemental iron may be prevented from forming in the reaction zone by introducing sufficient supplemental oxygen-containing material and/or sulfur-containing material into the reaction zone so as to keep the partial pressure of oxygen and/or S.sub.2 gas in the reaction zone slightly above that calculated from Formulae I and/or II. The refractory substantially resists corrosion, erosion, and chemical attack by the molten slag. The life of the refractory is extended. Further, the molten slag is modified by contact with the refractory so that it runs more freely from the gasifier. By this method molten slag having a reduced viscosity and containing the nickel and vanadium-containing impurities from the feedstock and refractory components is readily removed from the gas generator.

Abstract: Synthesis gas, fuel gas, or reducing gas is produced by the noncatalytic partial oxidation of a sulfur-containing liquid hydrocarbonaceous fuel or a slurry of sulfur-containing solid carbonaceous fuel with a free-oxygen containing gas in the free-flow reaction zone of a refractory lined gas generator at an autogenous temperature in the range of about 1900.degree. F. to 2900.degree. F. and above the ash-fusion temperature of the slag formed in the reaction zone, so that about 75 to 95 weight percent of the carbon in the fuel feed to the reaction zone is converted into carbon oxides. At least a portion of the hot effluent gas stream from the reaction zone is passed through a free-flow radiant cooler in admixture with an iron-containing additive. In the radiant cooler at least a portion of the sulfur-containing gases e.g. H.sub.2 S and COS react with the iron-containing additive to produce particulate matter comprising iron oxysulfide. Further, a portion of this newly formed particulate matter and/or the iron-containing additive combine with molten slag and/or ash in the hot raw gas stream passing through the radiant gas cooler. The slag produced thereby has a reduced ash fusion temperature and a reduced viscosity. The remainder of the newly formed particulate matter comprising iron oxysulfide and particulate carbon are entrained in the effluent gas stream leaving the radiant syngas cooler and are separated from the effluent gas stream and optionally recycled to the partial oxidation reaction zone in admixture with fresh fuel feed.

Abstract: A process for the simultaneous partial oxidation and desulfurization of sulfur and silicate-containing solid carbonaceous fuel for the production of gaseous mixtures comprising H.sub.2 and CO and containing less than about 0.05 volume % of H.sub.2 S and COS. In the process, an aqueous slurry of the solid carbonaceous fuel and a copper-containing compound are reacted by partial oxidation in the reaction zone of a free-flow unobstructed down-flowing vertical refractory lined gas generator with a controlled amount of free-oxygen containing gas and with optionally a temperature moderator so that an equilibrium oxygen concentration is provided in the gas phase in the reaction zone having a partial pressure which is less than about 10.sup.-6 atmosphere. The O/C atomic ratio is in the range of about 0.5 to 2.0. The H.sub.2 O/solid carbonaceous fuel weight ratio is in the range of about 0.2 to 0.7. Further, the total moles of copper in the reaction zone is at least equal to about 1.0 times the moles of sulfur in the solid carbonaceous fuel. The partial oxidation and desulfurization reactions take place simultaneously at a temperature which produces fly-ash or molten slag at an increased thermal efficiency. At least about 90 wt. % of the sulfur in the solid carbonaceous fuel in the reaction zone is converted into copper oxysulfide particulate matter which leaves the reaction zone along with the fly-ash or molten slag entrained in the hot raw effluent gas stream comprising H.sub.2, CO, CO.sub.2 at least one gas selected from the group consisting of H.sub.2 O, N.sub.2, CH.sub.4 and A; and less than about 0.05 volumne % of H.sub.2 S and COS.
