Abstract: A pumpable slurry of shredded scrap solid carbonaceous plastic-containing material that contains associated inorganic matter in admixture with a comminuted aluminosilicate-containing material having noncombustible constituents is reacted by partial oxidation to produce synthesis gas, reducing gas, or fuel gas. The noncombustible constituents in the aluminosilicate-containing material captures the inorganic matter in the scrap solid carbonaceous plastic-containing material while in the reducing atmosphere of the gasifier to produce nontoxic, nonleachable slag. The slurrying medium is water, liquid hydrocarbonaceous fuel, or mixtures thereof. Scrap plastics may be disposed of by the subject process without polluting the nation's environment.

Abstract: Reactor for gasifying a carbonaceous fuel to produce a usable gas, and comprising an insulated outer shell. A reaction chamber within the shell receives a fuel mixture from an injection burner. The products or effluent of gasification include hot produced gases which are passed through a constricted throat to be cooled in a liquid bath. A dip tube, which guides the hot effluent into the bath, is provided with a stream of coolant from a quench ring. The latter is supported below the reaction chamber and is provided with a thermal barrier along its surface that is exposed to the hot produced gas. The barrier will reduce thermal stress in the quench ring and reduce drain of heat from the gasifier throat, thus avoiding premature chilling of the slag component.

Abstract: An integrated liquefaction and gasification process converts bulk particulate halogen-containing waste plastic materials with minimal particle size reduction into a synthesis gas and a non-leachable, vitreous environmentally nontoxic slag. The process involves melting and cracking bulk particulate halogen-containing waste plastic material to form a lower boiling point, lower molecular weight halogen-containing oil composition which then undergoes partial oxidation in a quench gasifier to produce a synthesis gas. Any hazardous gases, liquids or solids that are produced can be purified into commercially valuable byproducts or recycled to the process, which does not release hazardous materials to the environment.

Abstract: A process for minimizing evaporator scaling during the recovery of liquids and solids from the aqueous effluent discharged during a partial oxidation gasification, wherein the aqueous effluent contains ammonium chloride (NH4Cl). The aqueous effluent is evaporated to produce a distillate water and a brine having an NH4Cl concentration of about 10 to 60 weight percent. The brine can be further concentrated and ammonium chloride crystals are recovered. The distillate water is recycled to the gasification reaction. No effluent discharges to the environment.

Abstract: A method is disclosed for recovering condensed solidified volatile metals from slag that exits the reactor section of a partial oxidation reactor. In a partial oxidation reactor, condensed solidified volatile metals become adsorbed onto the surface of the slag particles and other particulate matter associated with the gasification reaction, such as ash and soot. These particulate materials are removed and recovered. Finely divided slag particles are separated and contacted with a mineral acid to dissolve the adsorbed condensed volatile metals. An acid liquor is obtained from which the dissolved volatile metals are recovered by electrolysis.

Abstract: The present invention relates to a method for minimizing hydrogen halide corrosion in quench gasifier during the non-catalytic partial oxidation reaction of a halogen-containing hydrocarbonaceous feed, to produce a hydrogen halide-containing synthesis gas, finely divided particulate solids, and a nontoxic slag. The hydrogen halide-containing synthesis gas is contacted with water in the quench zone (14) of the gasifier (10). The quench water contains a neutralizing agent, in excess of the amount necessary to neutralize hydrogen halide acids present therein, to thereby form halide salts. The quench water containing the halide salts is purified to recover the halide salts. The saltfree water is essentially environmentally non-toxic and can either be recycled to the process or discarded in conformity with environmental regulations.
