“…The FTS is usually performed on cobalt or iron based catalysts. Many inorganic oxides such as Al 2 O 3 , SiO 2 , TiO 2 , and ZrO 2 are used as supports for improving the structural stability of catalysts [1][2][3][4]. The process variables such as reaction temperature, gas velocity, catalyst density, total pressure, and hydrogen to carbon monoxide (H 2 /CO) ratio affect the product distribution [5,6].…”
