摘要: A system and method for producing olefin via dry reforming and olefin synthesis in the same vessel, including providing feed including methane and carbon dioxide to the vessel, converting methane and carbon dioxide in the vessel into syngas (that includes hydrogen and carbon monoxide) via dry reforming in the vessel, and cooling the syngas via a heat exchanger in the vessel. The method includes synthesizing olefin from the syngas in the vessel, wherein the olefin includes ethylene, propylene, or butene, or any combinations thereof.

摘要: A process for preparing C2 to C4 hydrocarbons includes introducing a feed stream into a reaction zone of a reactor, the feed stream comprising hydrogen gas and carbon monoxide. An additional stream is introduced into the reaction zone of the reactor, the additional stream comprising carbon dioxide. A combined stream that includes the feed stream and the additional stream is converted into a product stream comprising C2 to C4 hydrocarbons in the reaction zone in the presence of a hybrid catalyst. The hybrid catalyst includes a mixed metal oxide catalyst component, and a microporous catalyst component. The process operates at a gas hourly space velocity in excess of 2500 hr-1 and effectively yields a net carbon dioxide selectivity of less than 5.0% and a productivity of C2-C4 hydrocarbons greater than 75 g hydrocarbons per kilogram of catalyst per hour.

摘要: Ammonia, methanol, Fischer Tropsch products, and derivatives thereof are made by using hydrogen and oxygen supplied from an electrolyzer that is at least partially powered by renewable power, resulting in green process and systems that produce green products disclosed herein. A process using biomass and renewable energy includes producing an unshifted syngas from biomass and oxygen in a gasification unit, introducing water into an electrolyzer to produce an oxygen product and a hydrogen product, and introducing the oxygen product to the gasification unit. The electrolyzer is powered by renewable energy, and the oxygen product supplies at least a portion of the oxygen to the gasification unit.

摘要: The present disclosure relates to a bifunctional catalyst for manufacturing a hydrocarbon from carbon dioxide and hydrogen. The bifunctional catalyst includes a carbon composite including cobalt (Co) and nitrogen (N) atoms forming a coordinate bond with the cobalt, and metal particles which exhibit a catalytic activity for a Fischer-Tropsch synthesis reaction and which are dispersed on the inner pore surface and/or the outer surface of the carbon composite support, thus simultaneously promoting a reverse water gas shift reaction and the Fischer-Tropsch synthesis reaction.
