Effects of Reaction Conditions on Cobalt-Catalyzed Fischer-Tropsch Synthesis: Interactions between Operating Factors

Abstract

In Fischer-Tropsch Synthesis, because of few reactants (<TEX>$H_2$</TEX>, CO), scarce operating parameters affected on efficiency especially the selectivity of products. In this research, effect of operating parameters on the selectivity of Co-Mn-<TEX>$TiO_2$</TEX> Fischer-Tropsch synthesis catalyst were studied by design of experimental procedure and Taguchi method. According to this research, interactions between operating factors have a crucial effect on light products selectivity. Among these interactions, (temperature<TEX>${\times}$</TEX>feed ratio) has the main influence on light hydrocarbons selectivity. It was concluded that temperature and feed ratio (<TEX>$H_2$</TEX>/CO) were the most integral operating parameters for much greater selectivity of light hydrocarbons.
