As alternative future energy sources, natural gas and coal has been suggested because they can be converted to the transportation fuels such as diesel and gasoline by Fischer–Tropsch synthesis (FTS) to relieve limited petroleum reservoirs and the global warming problems. Also the control of  mass diffusion and heat limitation in a FTS reactor are key factors. The effect of active metal loading, type of catalysts and size of catalyst on selectivity are caused by mass diffusion and heat limitation in the FTS process. A series of cobalt gamma alumina based catalyst were prepared by an impregnation method. The prepared catalysts were characterized by N2 physisorption, XRD, XPS, TPR and SEM/EDX techniques. The  catalytic performance for FTS over the granule type FT catalyst was investigated  in a fixed bed reactor system with the H2/ CO  ratio of 2:1, reaction temperature of 230°C and reaction pressure of 20 bar.
