Kinetic Study of Fischer Tropsch Synthesis over co Precipitated Iron-Cerium Catalyst
The kinetic of Fischer-Tropsch synthesis over a co-precipitated Fe-Ce catalyst was investigated in a fixed bed micro reactor. Experimental conditions were varied as follow: reaction pressure 1-15bar, H¬¬¬2/CO feed ratio of 1-3 and space velocity of 3600-5400 h-1 at the temperature range of 270-310°C. 4 models according to the Langmuir-Hinshelwood-Hougen-Watson (LHHW) type rate equation were der...
متن کاملKCl Promoted Cobalt-iron Nanocatalysts Supported on Silica: Catalytic Performance and Characterization in Fischer-Tropsch Synthesis
The SiO2 supported cobalt-iron nano catalysts were prepared by the sol-gel method. This research investigated the effects of (Co/Fe) wt.%, different Co/Fe ratio at different temperature and loading of KCl wt.% for Fisher-Tropsch synthesis (FTS). The results were showed that the catalyst containing 50 wt.% (Co/Fe)/SiO2 (Co/Fe ratio is 70/30) which promoted with 0.6 wt.% KCl is an optimal nano ca...

متن کاملEffect of calcium promoter on nano structure iron catalyst for Fischer–Tropsch synthesis
The Fischer-Tropsch synthesis (FTS) has been recognized as a heterogeneous surface-catalyzed polymerization process. During this process, CHx monomers formed via the hydrogenation of adsorbed CO on transition metals produce hydrocarbons and oxygenates with a broad range of chain lengths and functional groups. A series of Fe/Cu Fischer-Tropsch synthesis catalysts incorporated with a calcium prom...
متن کامل281. Promoted Hydrotalcite Based Cobalt Catalyst for Fischer Tropsch Synthesis Application
The effects of using different promoters on hydrotalcite based cobalt (HT-Co) catalyst for FischerTropsch Synthesis was studied in this paper. The HT-Co catalysts were synthesized by using hydrothermal method whereas zinc and zirconium were added separately as promoters, by wetness impregnation method. The main aim of the study is to see the difference in properties of both zinc and zirconium p...
