Abstract: THIS PROCESS PERTAINS TO THE ABATEMENT OF POLLUTION FROM SULFIDE-BEARING WASTE WATERS. WASTE AQUEOUS SOLUTIONS E.G., SOUR WATER, TREATED SOUR WATER, AND OTHER REFINERY WASTE WATERS CONTAINING SULFIDES ARE ADMIXED WITH A HYDROCARBONACEOUS FUEL AND REACTED BY PARTIAL OXIDATION WITH AN OXYGEN-RICH GAS IN A FREE-FLOW NONCATALYTIC GAS GENERATOR AT AN AUTOGENOUS TEMPERATURE IN THE RANGE OF ABOUT 1500 TO 3500*F. AND A PRESSURE IN THE RANGE OF ABOUT 1 TO 250 ATMOSPHERAS TO PRODUCE SYNTHESIS GAS FROM WHICH HYDROGEN SULFIDE MAY BE SUBSEQUENTLY RECOVERED AND CONVERTED INTO BY-PRODUCT SULFUR.

Abstract: Production of synthesis gas from a slurry of particulate solid carboniferous fuels, e.g., petroleum coke, coke from bituminous coal, coal, oil shale, tar sands, pitch, or mixtures of these materials in water or in a hydrocarbon liquid fuel. The amount of particulate solid carboniferous fuel in a pumpable slurry may be increased to 75 wt. percent and the particle size of the solid fuel may be increased to pass through a 12 mesh screen by the addition of 2 to 10 wt. percent of soot as produced, for example, by the partial oxidation of crude oil. The slurry at a relatively low velocity in the range of 5 to 50 feet per second is mixed with a stream of oxidizing gas at a relatively high velocity in the range of 200 feet per second to sonic velocity at the burner tip to form an atomized dispersion of water, hydrocarbon liquid fuel, oxidizing gas, and solid carboniferous fuel. Under synthesis gas generating conditions, the atomized dispersion is reacted to produce a gaseous mixture of hydrogen and carbon monoxide. By this process, pumpable slurry feeds of low cost solid carboniferous fuels may be gasified in a synthesis gas generator without being preheated.

Abstract: A NONCATALYTIC MULTI-HYDROTORTING PROCESS FOR MAXIMIZING THE CONVERSION OF COAL INTO COAL OIL. A PUMPABLE COAL-WATER SLURRY IN ADMIXTURE WITH A STREAM OF SYNTHESIS GAS IS PASSED THROUGH A TUBULAR RETORT WHERE IT IS HEATED TO A TEMPERATURE IN THE RANGE OF ABOUT 600 TO 950* F. IN THE ABSENCE OF AIR. THE SOLID COAL PARTICLES ARE FRAMENTIZED AND CARBONIZED IN THE TUBULAR RETORT, THE VOLATILE CONSTITUENTS IN SAID SLURRY ARE VOLATILIZED AND SIMULTANEOUSLY HYDROGENATION OF THE PROCESS STREAM TAKES PLACE. THE EFFLUENT FROM THE TUBULAR RETORT IS THEN INTRODUCED INTO A FLUIDIZED BED RETORT ALONG WITH A SECOND STREAM OF SYNTHESIS GAS. THERMAL DECOMPOSITION OF THE CARBONACEOUS MATERIALS TAKES PLACE IN THE ABSENCE OF AIR AND THE PROCESS STREAM IS HYDROGENATED FOR A SECOND TIME. THE PROCESS STREAM LEAVING THE FLUIDIZED BED RETORT IS COOLED TO CONDENSE OUT AND SEPARATE WATER AND RAW COAL-OIL IN A GAS-LIQUID SEPARATION ZONE. A PORTION OF THE OFF-GAS FROM THE GAS-LIQUID SEPARATOR MAY BE SCRUBBED AND PURIFIED TO PRODUCE NONPOLLUTING FUEL GAS HAVING A HIGH HEATING VALUE. SPENT CARBONACEOUS PARTICLES LEAVING THE FLUIDIZED BED RETORT AND OPTIONALLY A PORTION OF THE OFF-GAS FROM THE GAS-LIQUID SEPARATOR ARE INTRODUCED INTO A FREE-FLOW NONCATALYTIC GAS GENERATOR FOR CONVERSION INTO PREFERABLY HYDROGEN-RICH SYNTHESIS GAS BY PARTIAL OXIDATION FOR USE IN THE AFORESAID TWO HYDROTORTING STAGES.

Abstract: D R A W I N G
THIS IS A NONCATALYTIC MULTIHYDROTORTING PROCESS FOR MAXIMIZING THE CONVERSION OF COAL INTO NONPOLLUTING FUEL GAS. A PUMPABLE COAL-WATER SLURRY IN ADMIXTURE WITH A STREAM OF SYNTHESIS GAS IS PASSED THROUGH A TUBULAR RETORT WHERE IT IS HEATED TO A TEMPERATURE IN THE RANGE OF ABOUT 600 TO 1300*F. IN THE ABSENCE OF AIR. THE SOLID COAL PARTICLES ARE FRAGMENTIZED AND CARBONIZED IN THE TUBULAR RETORT. THE VOLATILE CONSTITUENTS IN SAID SLURRY ARE VOLATILIZED AND SIMULTANEOUSLY HYDROGENATION OF THE PROCESS STREAM TAKES PLACE. THE EFFLUENT FROM THE TUBULAR RETORT IS THEN INTRODUCED INTO A FLUIDIZED BED RETORT ALONG WITH A SECOND STREAM OF SYNTHESIS GAS. THERMAL DECOMPOSITION OF THE CARBONACEOUS MATERIALS TAKES PLACE IN THE ABSENCE OF AIR AND THE PROCESS STREAM IS HYDROGENATED FOR A SECOND TIME. OFF-GAS FROM THE FLUIDIZED BED IS THEN SCRUBBED AND PURIFIED TO PRODUCE NONPOLLUTING FUEL GAS HAVING A HIGH HEATING VALUE. SPENT CARBONACEOUS PARTICLES LEAVING THE FLUIDIZED BED RETORT ARE INTRODUCED INTO A FREE-FLOW NONCATALYTIC GAS GENERATOR FOR CONVERSION INTO PREFERABLY METHANE-RICH SYNTHESIS GAS BY PARTIAL OXIDATION FOR USE IN THE AFORESAID TWO HYDROTORTING STAGES.
