Fischer-Tropsch synthesis over bimetallic CoxFey/HMS catalysts

Trabajo presentado en el 23rd North American Meeting of the Catalysis Society, celebrado en Louisville (Estados Unidos) del 2 al 7 de junio de 2013.The renewable "green gasoline and diesel" from biomass are of special interest. The Fischer-Tropsch Synthesis (FTS) is an attractive alternative for the production of ultra-clean sustainable and renewable free-sulfur liquid fuels from syngas conversion. FTS is of great industrial importance due to the great variety of hydrocarbon products obtained, whose abundance depends on the catalysts employed, as well as on operating conditions. Recently, it was found that Co/HMS catalysts showed higher catalytic performance and selectivity toward C5+ products than the Co/MCM-41 counterpart. The superior performance of Co/HMS sample was ascribed to their smaller domain size with shorter channels and larger textural mesoporosity. Lira and co-workers compared Co/HMS and Co/SiO2 catalysts in the FTS. Both catalysts showed selectivity toward C5+ products, specifically towards the diesel fraction (C11-C19).Peer Reviewe
