Abstract
Abstract Production of synthesis gas from a slurry of particulate solid carboniferous fuel e.g., petroleum coke, coke from bituminous coal, coal, oil shale, tar sands, pitch, or mixtures of said solid fuels in water or in a hydrocarbon liquid fuel. Pumpable slurries containing 1-60 weight percent of ground solid carboniferous fuel in petroleum oil and 25-55 weight percent of ground solid carboniferous fuel in water 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 particulate 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, slurry feeds of low cost solid carboniferous fuels may be gasified without being preheated.
