摘要： The hot process gas stream from the partial oxidation of sulfur-containing heavy liquid hydrocarbonaceous fuel and/or sulfur-containing solid carbonaceous fuel comprising gaseous mixtures of H.sub.2 +CO, sulfur-containing gases, entrained particulate carbon, and molten slag is passed through the unobstructed central passage of a radiant cooler where the temperature is reduced to a temperature in the range of about 1800.degree. F. to 1200.degree. F. From about 0 to 95 wt. % of the molten slag and/or entrained material may be removed from the hot process gas stream prior to the radiant cooler with substantially no reduction in temperature of the process gas stream. In the radiant cooler, after substantially all of the molten slag has solidified, the sulfur-containing gases are contacted with a calcium-containing material to produce calcium sulfide. A partially cooled stream of synthesis gas, reducing gas, or fuel gas containing entrained calcium sulfide particulate matter, particulate carbon, and solidified slag leaves the radiant cooler containing a greatly reduced amount of sulfur-containing gases.

摘要： A partial oxidation process and a novel burner are provided for simultaneously introducing two or three separate feedstreams into a free-flow partial oxidation gas generator for the production of synthesis gas and fuel gas, or reducing gas. The reactant feedstreams include a liquid hydrocarbonaceous fuel or a pumpable slurry of solid carbonaceous fuel, and a free-oxygen containing gas e.g. air or oxygen. The burner comprises a central conduit and a plurality of spaced concentric coaxial conduits with down-flowing annular passages. A flat annular-shaped disc or cup-shaped porous ceramic or porous metal cooling means of uniform composition, wall thickness and porosity with the various pores interconnecting is attached to the downstream tip of the burner. A controlled amount of liquid coolant under pressure is passed successively through the porous inside surface, porous core and porous outside surface of the cooling means is vaporized. The tip of the burner is thereby cooled. Stress cracking of the burner tip is prevented; and the life of the burner is extended. Further, deposition of ash on the face of the burner is prevented.

摘要： Synthesis gas, reducing gas, or fuel gas is produced by the partial oxidation of ash-containing solid carbonaceous and/or liquid hydrocarbonaceous fuel at an autogenous temperature in the range of about 20.degree. F. to 200.degree. F. below the softening temperature of the ash in said fuel, and at a pressure in the range of about 17 to 100 atmospheres to produce a raw effluent gas stream containing entrained carbon-rich fly-ash which is separated from the effuent gas stream. A fuel mixture comprising about 20 to 100 wt. % of said carbon-rich fly-ash and about 0 to 80 wt. % of a supplemental fuel is reacted by partial oxidation at an autogenous temperature of about 100.degree. F. above the ash-fusion temperature, and at a reduced pressure e.g. in the range of about 1 to 16 atmospheres and at least 16 atmospheres below the pressure in the partial oxidation reaction used to produce said carbon-rich fly-ash. By reducing the pressure less carbon-rich particulate material is produced in the second partial oxidation reaction at a significant cost savings and improved process efficiency.
