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:
Scrubbing a gas by injecting a wash liquid directly into a high speed jet stream formed by passing said gas thru a restricted plate orifice at a substantial pressure, atomizing the wash liquid in the jet stream and thereafter coalescing the water droplets containing contaminant materials.
Abstract:
IMPROVED FUEL COMPOSITION COMPRISING ABOUT 1 TO 80 WEIGHT PERCENT OF AN OXYGENATED HYDROCARBONACEOUS ORGANIC MATERIAL CONTAINING ABOUT 5 TO 60 WEIGHT PERCENT OF COMBINED OXYGEN AND ACARBONIFEROUS FUEL IN THE AMOUNT OF ABOUT 20 TO 99 WEIGHT PERCENT. THE SUBJECT FUEL COMPOSITION IS ESPECIALLY SUITABLE AS FEEDSTOCK FOR A PARTIAL OXIDATION GAS GENERATOR FOR PRODUCING SYNTHESIS GAS OR FUEL GAS
Abstract:
Fuel gas suitable for use in conjunction with a gas turbine is prepared by subjecting a hydrocarbon oil to partial combustion using air as the oxidizing medium and injecting additional hydrocarbon oil into the hot partial combustion products.
Abstract:
A PROCESS FOR THE PRODUCTION OF METHANEE FROM CARBONACEOUS FUELS OF GREATER MOLECULAR WEIGHT THAN METHANE BY A NON-CATALYTIC, DIRECT PARTIAL OXIDATION REACTION IN WHICH THE CARBONACEOUS FUEL AND OXYGEN ARE REACTED IN THE PRESENCE OF HYDROGEN AND CARBON MONOXIDE, OPTIONALLY WITH THE ADDITION OF STEAM, AT AN AUTOGENOUS TEMPERATURE IN THE RANGE OF 1200 TO 2200* F. AND AT A PRESSURE IN THE RANGE OF 300 TO 4500 POUNDS PER SQUARE INCH. CARBON MONOXIDE AND HYDRROGEN FROM THE PRODUCT ARE PREFERABLY TOTALLY RECYCLED TO THE REACTION SO THAT ULTIMATE PRODUCTS OF THE PROCESS ARE METHANE, CARBON DIOXIDE, AND HYDROGEN SULFIDE IF THE CARBONACEOUS FUEL CONTAINS SULFUR. SUBSTANTIALLY PURE METHANE, SUITABLE AS FUEL GAS OR PIPELINE GAS MAY BE PRODUCED FROM RELATIVELY LOW GRADE FUELS AND TRANSPORTED BY PIPELINE TO POINTS OF COMSUMPTION.
