摘要: This invention relates to a process for catalytic dehydrocyclodimerization wherein the reaction mixture contains from about 10 to about 200 wt. ppm water. Providing water in the reaction mixture allows for an extended life of the zeolitic catalyst thereby increasing the efficiency of the catalytic dehydrocyclodimerization process.

摘要: The present invention provides a system and method for producing hydrocarbons from biomass. The method is particularly useful for producing substitute natural gas from forestry residues. Certain disclosed embodiments convert a biomass feedstock into a product hydrocarbon by fast pyrolysis. The resulting pyrolysis gas is converted to the product hydrocarbon and carbon dioxide in the presence of hydrogen and steam while simultaneously generating the required hydrogen by reaction with steam under prescribed conditions for self-sufficiency of hydrogen. Methane is a preferred hydrocarbon product. A system also is disclosed for cycling the catalyst between steam reforming, methanation and regeneration zones.

摘要: Systems and methods for regenerating a spent catalyst are provided. The method can include heating a hydrocarbon and a coke precursor in the presence of catalyst particles to provide a cracked hydrocarbon product and coked catalyst particles. The cracked hydrocarbon product and the coked catalyst particles can be selectively separated to provide a hydrocarbon product and coked catalyst particles. The coked catalyst particles can be mixed with a carrier fluid to provide a mixture. The mixture can be introduced to an upper surface of a dense phase catalyst zone disposed within a regenerator. A gas can be introduced to a lower zone of the dense phase catalyst zone. At least a portion of the carbon deposited on the coked catalyst particles can be combusted to provide a flue gas, heat, and a regenerated catalyst.

摘要: A process for regenerating a palladium catalyst from a catalytic reaction where the catalyst is contaminated with at least carbon. The regenerating is conducted prior to any heating step under oxidizing conditions in the regenerating section. The regenerating involves at least one heating step under a hydrogen-containing reducing atmosphere and under conditions sufficient to lower the content of carbon in the palladium catalyst.
