Abstract: A process for upgrading plastic material containing inorganic filler or reinforcement material for use as feedstock in a partial oxidation gas generator for the production of raw synthesis gas, fuel gas, or reducing gas. The plastic material is granulated and partially liquefied by heating in a closed autoclave at a temperature in the range of about 400.degree. F. to 495.degree. F. and a pressure in the range of about 150 psig to 750 psig while the plastic material is in contact with a pumpable hydrocarbonaceous liquid solvent. A pumpable slurry is thereby produced comprising solubilized plastic, unsolubilized plastic, hydrocarbonaceous liquid solvent, separated inorganic material and unseparated inorganic material. After removing the separated inorganic material, the remainder of the slurry is then reacted by partial oxidation to produce said raw synthesis gas, fuel gas or reducing gas.

Abstract: A selective deslagging operation is conducted in a partial oxidation reactor wherein a first predetermined portion of the reactor is selectively deslagged by derivatization while limiting derivatizing slag conditions in a second predetermined portion of the reactor. Selective deslagging can be accomplished by controlled oxidation conditions in the reactor that vary from one predetermined portion of the reactor to another. Thus, the slag present in one predetermined portion is derivatized and fluidized for removal from the reactor at a faster rate than the slag present in another portion of the reactor, which is not derivatized or is subjected to more limited derivatizing slag conditions. Derivatized slag can be differentiated from non-derivatized slag that does not flow or more limited derivatized slag that has a lower mass flow rate then the derivatized slag at conditions of controlled oxidation. The derivatized slag can then be selectively removed because it has attained a lower fluidizing temperature.

Abstract: A gasifier for partially combusting a carbonaceous fuel mixture in the combustion chamber of the gasifier. The latter includes a water bath into which the hot effluent or products of combustion are immersed, including a synthetic gas. The products of combustion are directed into the bath by way of a constricted throat section. To avoid excessive erosion action and/or thermal shock to the throat section as a result of exposure to the effluent's high temperatures, the throat section is structured with an internal framework of pipes. The framework is communicated with a pressurized source of a cooling fluid, preferably water, whereby to cool the throat section sufficiently to counteract the ill effects of exposure to contact with the high temperature effluent.

Abstract: A process is provided for continuously controlling the hydrocarbon heat content and flow rate of a partial oxidation unit feed-gas stream under conditions where the composition and hence the hydrocarbon heat content of the feed-gas stream is subject to variation. The hydrocarbon heat content of the incoming gases is continuously measured and compared against a design hydrocarbon heat content. An evaluating means calculates whether a moderator is required to decrease the hydrocarbon heat content to the design hydrocarbon heat content or a supplemental high hydrocarbon heat content gas is required to increase the hydrocarbon heat content to the design hydrocarbon heat content. The process utilizes recycle synthesis gas as a moderator.

Abstract: A process for converting scrap plastic material into a high quality transportation fuel. The plastic material is granulated and mixed with granulated solid carbonaceous fuel e.g. coal and liquid hydrocarbonaceous solvent e.g. waste motor oil to produce a plastic-containing sludge. The plastic-containing sludge is liquefied in a closed autoclave while in contact with hydrogen gas. A pumpable slurry from the autoclave is heated and fractionated in a fractionation zone to produce a hydrocarbonaceous distillate which may be used for transportation fuel. A bottoms stream from the fractionation zone comprising liquid hydrocarbonaceous material and inorganic material is reacted by partial oxidation to produce nontoxic slag and raw synthesis gas, fuel gas or reducing gas which may be purified in a gas purification zone.
