Abstract: A continuous process for producing simultaneously a stream of cooled clean synthesis gas, reducing gas, or fuel gas and a separate stream of superheated steam. In the subject process a hydrocarbonaceous fuel is reacted with a free-oxygen containing gas by partial oxidation in the reaction zone of a free-flow noncatalytic gas generator. The effluent gas stream from the reaction zone is quenched in water in a quench zone and further cooled by being passed serially through first and second heat exchange zones to produce a product gas stream of cooled clean synthesis gas, fuel, or reducing gas. Simultaneously, a stream of boiler feed water is converted into superheated steam by stepwise sequential indirect heat exchange with the following sources of heat: first with a stream of carbon-quench water dispersion from said quench zone, second with said effluent gas stream in said second heat exchange zone, and third with the effluent gas stream in said first heat exchange zone. Optionally, the process gas stream may be cooled further, scrubbed with water, passed through a separating zone to remove entrained water, and expanded in a gas turbine for the production of mechanical or electrical energy.

Abstract: Free carbon soot entrained in the product gas of a free-flow synthesis gas generator is recovered in a sedimentation vessel as part of a thickened dispersion of solids in water from which clear supernatant water is easily separated by supplying particulate petroleum coke to the sedimentation vessel or to the reaction zone of said gas generator as a portion of the fuel, or by mixing the carbon soot-water dispersion in the sedimentation vessel with a thickened water slurry of unconverted petroleum coke such as produced by quenching in water the product gas of a second free-flow synthesis gas generator in which the fuel comprises raw particulate petroleum coke and the thickened underflow from said sedimentation vessel.
