Cobalt–iron nano catalysts supported on TiO2–SiO2: Characterization and catalytic performance in Fischer–Tropsch synthesis

Preparation and characterization of promoted Fe–Mn/ZSM-5 nano catalysts for CO hydrogenation

“…The ZSM-5 zeolite is one of the most active catalysts which are frequently used in the petrochemical industry and FTS [29,30]. The Fe/ZSM-5 catalyst is selective to gasoline range hydrocarbons [31,32]. The aim of this study was to investigate effects of Fe loading, promoters, loading of optimal promoter and calcination conditions on catalytic performance of Fe catalysts supported on ZSM-5 zeolite for FTS.…”

Influence of Fabrication Temperature and Time on Light Olefin Selectivity of Iron–Cobalt–Cerium Mixed Oxide Nanocatalyst for CO Hydrogenation

“…Arsalanfar et al 16 studied the effect of operating conditions on a Fe−Co catalyst promoted by Mn prepared by a coprecipitation method. These findings showed that the highest selectivity toward light olefins was achieved at 573 K. Also Feyzi et al 17 Comparatively some literature works reported on Fe−Ce and Co−Ce bimetallic catalysts using Fischer−Tropsch synthesis; e.g., Perez-Alonso et al 18 demonstrated iron−cerium mixed oxide systems prepared by different methods. The result showed that Fe−Ce bimetallic catalysts had higher selectivity to olefins than unpromoted Fe catalyst and catalyst prepared by physical mixture of Fe and Ce oxides.…”

A Modeling Study of Operating Conditions and Different Supports on Fe-Co-Ce Nanocatalyst and Optimizing of Light Olefins Selectivity in the Fischer-Tropsch Synthesis

“…Recently a lot of researches have been carried out on the effect of operating GHSV in a catalytic performance. Feyzi et al [5] reported the optimal operating GHSV = 2000 h -1 in order to achieve higher light olefins C 2 -C 4 selectivity. Arsalanfar et al [6] investigated the effect of various space velocities on catalytic performance of Fe-Co-Mn catalyst supported by MgO prepared using co-precipitation method.…”

“…Moreover, bimetallic catalysts indicate various distributions of products. Some researchers studied the effects of preparation and operating conditions on bimetallic catalysts [5,6]. The vital variables to FT process, which influence lifetime, activity and selectivity of the product, are operating conditions such as feed gas composition H 2 /CO, and gas resistance time (GHSV).…”
