    Abstract: This is an improved continuous process for producing a clean methane-rich gas stream without the concomitant formation of particulate carbon which would ordinarily decrease the efficiency of the process and shorten the life of the catalyst. By-product superheated steam is simultaneously produced at a maximum temperature. The product stream may have a methane content up to 98 to 99 mole % or higher and a gross heating value up to 1000 BTU per SCF or more. Process steps include partial oxidation of a hydrocarbonaceous fuel under operating conditions that produce a synthesis gas containing 10 to 30 mole % methane (dry and CO2free basis) and a H2/CO mole ratio of 2.6 or higher, and reacting the methane-rich process gas stream in one to three catalytic methanation stages under critical operating conditions that increase the methane content in the process gas stream stepwise up to 98 mole % or higher without incipient soot formation for each corresponding CH4 content of the feed as one proceeds from one methanation step to another. Heat from the highly exothermic methanation reaction is used to make valuable by-product superheated steam. The product gas may be burned without polluting the atmosphere.

    Abstract: A process for producing synthesis gas under substantially endothermic gasification conditions, which comprises: (a) feeding an organic feed material, containing hydrogen and at least 10 weight percent oxygen and containing less than 5 weight percent sulfur, to a reaction zone; (b) feeding steam to the reaction zone; and (c) contacting the steam with the organic feed material in the reaction zone at a temperature between about 500* and 1,600*F. Preferably the feed material is solid waste material, most preferably solid municipal waste.

    Abstract: A method of feeding solid carbonaceous material to a gasifier operating under conditions of high temperature and pressure by forming a slurry of the carbonaceous material and a liquid vehicle, raising the internal pressure of the slurry to the operating level of the gasifier, drying the carbonaceous material by entraining the carbonaceous material in a hot gas stream, and thereafter separating the carbonaceous material and feeding the carbonaceous material to the gasifier. The method is adaptable to using the gasifier effluent to dry the carbonaceous material and includes using process materials such as char accumulated from the process and condensing steam to provide a portion of the source of carbonaceous materials and vehicle for the slurry.
