摘要： Coal or similar liquefiable carbonaceous solids are converted into lower molecular weight liquids by contacting the feed solids with molecular hydrogen in the absence of externally added hydrocarbon liquids under liquefaction conditions during sequential residence in two or more liquefaction zones arranged in series and operated such that the temperature in each zone increases from the first to the final zone. The effluent from each liquefaction zone is passed to the next succeeding higher temperature zone in the series. No hydrocarbon liquids are added to the first zone in the series and the only liquids present in each succeeding zone of the series are the liquids in the effluent from the preceding zone. Liquid hydrocarbonaceous products are recovered from the effluent withdrawn from the last zone.

摘要： This invention relates to a catalytic process for converting a carbonaceous material to a liquid product. More specifically, this invention relates to a process for hydroconverting coal in a hydroconverting zone to liquid hydrocarbon products in the presence of a catalyst prepared in situ, with the catalyst being added to a mixture of coal and solvent as an oil soluble metal compound. An increased quantity of liquid product is achieved by incorporating a hydrocracking zone into the process.

摘要： A novel fluidized bed syngas (FBSG) injector/reactor apparatus and an efficient process for the partial oxidation and steam reforming of light hydrocarbon gases such as methane, to convert such gases to useful synthesis gas containing CO and H.sub.2 for recovery and/or subsequent hydrocarbon synthesis. Sources of a light hydrocarbon gas, such as methane, and oxygen or an oxygen-containing gas are preheated and pressurized and injected through gas orifices of an injector at high velocity and comparable momentums into admixture with each other in the desired proportions, at a plurality of mixing chambers or recessed cups which are open to the fluidized bed reaction zone of a reaction chamber and are spaced over the face of the injector, to form a reactant gas premix having a pressure drop of at least 1% through the injector. The gaseous premix is injected in a time period which is less than its autoignition time, preferably less than 9 milliseconds, at a velocity between about 25 to 1000 feet/second, into a partial oxidation reaction zone comprising a fluid bed catalyst so that the gas mixture reacts in the catalyst bed, to reduce the amounts of CO.sub.2, H.sub.2 O and heat produced by the partial oxidation reaction to favor the desired stoichiometry. The formed syngas is cooled and recovered, such as use in further synthesis processing.

摘要： Metal constituents are recovered from the heavy bottoms produced during the liquefaction of coal and similar carbonaceous solids in the presence of a catalyst containing a metal capable of forming an acidic oxide by burning the heavy bottoms in a combustion zone at a temperature below the fusion temperature of the ash to convert insoluble metal-containing catalyst residues in the bottoms into soluble metal-containing oxides; contacting the oxidized solids formed in the combustion zone with an aqueous solution of a basic alkali metal salt to extract the soluble metal-containing oxides in the form of soluble alkali metal salts of the metal-containing oxides and recycling the soluble alkali metal salts to the liquefaction zone. In a preferred embodiment of the invention, the bottoms are subjected to partial oxidation, pyrolysis, coking, gasification, extraction or a similar treatment process to recover hydrocarbon liquids and/or gases prior to the burning or combustion step.
