Abstract

Using wet impregnation method, a novel ternary system of silica supported Fe-Co-Ce catalyst was prepared. Preparation conditions such as impregnation time and temperature, drying time and temperature, were optimized by the L9 Taguchi experimental design to achieve a light olefin selective catalyst with maximum CO conversion in a fixed bed micro-reactor. It was found that the best conditions to maximize the responses were obtained at 4h impregnation time, 60°C impregnation temperature, 6h drying time, 90°C drying temperature and 350°C of reaction’s temperature. Characterization of the optimal catalyst precursors and calcined samples before, and after the Fischer-Tropsch reaction was carried out using various techniques.
