Preparation of cobalt-based Fischer-Tropsch Synthesis

Fischer-Tropsch Synthesis is a process for obtaining second-generation biofuels i.e.the BTL process as well as for producing chemical feedstock or motor fuels withoutthe production of the environmentally harmful compounds encountered in directhydrogenation [۱,۲]. It has been found that several metals such as nickel, cobalt,ruthenium, and iron can be activated for FT reaction [۳]. Fe and Co catalysts are themost common commercial FT synthesis catalysts. The Co catalysts are preferred dueto their high FT synthesis activity, high selectivity to long-chain hydrocarbons,better catalyst stability in hydrogen-rich environments, and lower selectivity tooxygenated compounds [۴,۵]. In this study, a cobalt-based catalyst was prepared bythe incipient wetness impregnation method. The catalyst was characterized usingXRD, BET, H۲-TPR, and ICP techniques. The catalyst was tested in a fixed-bedreactor under FTS conditions. The results were shown ۷۰.۶ % CO conversion, ۱۲.۴% CH۴, ۶.۵ % C۲-C۴, and ۸۲.۱ % C۵+ selectivity
