This invention relates to a power recovery process in waste steam/CO2 reformers in which a waste stream can be made to release energy without having to burn the waste or the syngas. This invention in some embodiments does not make use of fuel cells as a component but makes use of exothermic chemical reactors using syngas to produce heat, such as Fischer-Tropsch synthesis. It also relates to control or elimination of the emissions of greenhouse gases in the power recovery process of this invention with the goal of producing energy in the future carbonless world economy.
摘要:
An integrated process for the production of a useful liquid hydrocarbon product comprises: feeding a gasification zone with an oxygen-containing feed and a first carbonaceous feedstock comprising waste materials and/or biomass, gasifying the first carbonaceous feedstock in the gasification zone to produce first synthesis gas, partially oxidising the first synthesis gas in a partial oxidation zone to generate partially oxidised synthesis gas, combining at least a portion of the first synthesis gas and/or the partially oxidised synthesis gas and at least a portion of electrolysis hydrogen obtained from an electrolyser in an amount to achieve the desired hydrogen to carbon monoxide molar ratio of from about 1.5:1 to about 2.5:1, and to generate a blended synthesis gas, wherein the electrolyser operates using green electricity; and subjecting at least a portion of the blended synthesis gas to a conversion process effective to produce the liquid hydrocarbon product.

摘要:
A catalytic reaction module (10) for performing an endothermic reaction such as steam methane reforming, includes separate reactor blocks (12), each reactor block defining a multiplicity of first and second flow channels (15, 16) arranged alternately within the block to ensure thermal contact between the first and second flow channels. The reactor blocks (12a, 12b) may be arranged and connected for series flow of a combustible gas mixture in the first flow channels (15) and also of a gas mixture to undergo the endothermic reaction in the second flow channels (16). This enables the combustion process to be carried out in stages, with the option of cooling the combustion gases between stages, and introducing additional fuel and additional air.
摘要:
A method for heating or cooling a carbon containing reducing gas having a carbon monoxide content of at least 0.5 vol %, wherein the gas is heated to a temperature of at least 400° C. or wherein the gas is cooled from a temperature exceeding 400° C., wherein the gas is passed along a surface of a heating or cooling unit having a heat conductive metal or metal alloy body and a protective layer, which protective layer provides said surface, and which protective layer is made from a coating composition including colloidal amorphous silicate and crystalline oxide particles.

A Fischer Tropsch (“FT”) unit that includes an FT tube that is packed with a catalyst. The catalyst is designed to catalyze an FT reaction to produce a hydrocarbon. An insert that is positioned within the FT tube. The insert comprises at least one cross-piece that contacts an inner surface of the FT tube and at least one cross-fin extending from the cross-piece. There may be a corresponding second cross-fin adjacent each cross-fin. Both the cross-fins and the second cross-fins may be disposed radially outwardly such that the edge of the cross-fins are closer to the inner surface of the FT tube than is the base of the cross-fins.
