LOW TEMPERATURE FISCHER-TROPSCH SYNTHESIS USING IRON-BASED CATALYSTS WITH ENHANCED REDUCIBILITY
IntroductionRecently, the high oil price above 120 USS/barrel results in the deep interest of developing alternative technology for manufacturing clean and economic synthesis fuel for transportation I. Coal-to-liquid (CTL) process can be one promising and effective route of producing synthesis fuel in mass production 2. Development of Fisher-Tropsch synthesis (FTS) catalyst and reactor system is one of core technologies of the CTL process. FTS can be summarized as series reactions of synthesis gas that can produce a wide range of hydrocarbon fuels such as olefins, paraffins, and oxygenated compounds. The FTS process produces diverse kinds of olefins and paraffins of different chain length, highly depending upon the nature of the catalysts and the reaction temperatures. Iron-based catalysts are highly promising for this process due to their high activity and low cost. Furthermore, the use of iron-based catalysts can show a considerable merit for the FTS with low H2/CO ratio synthesis gas, especially derived from coal gasification, because of their potential activity for water-gas shift reaction (WGSR). Furthermore as expected thermodynamically, lower reaction temperatures favor the formation of higher carbon number products with higher alkene to alkane ratios. In this work, modified iron-based catalysts were developed with enhanced reducibility for low temperatures Fischer Tropsch synthesis (LTFT).
