Abstract: SFT418 catalyst, a Fe-Co-Cu-K-SiO2 catalyst having dual active centers for low temperature Fischer-Tropsch (F-T) synthesis process, was developed by China Shenhua Coal to Liquid and Chemical Beijing Institute. An application performance test of SFT418 catalyst obtained from a commercial trial was carried out on a self-developed pilot plant of F-T synthesis process (CEU) under the commercial operation conditions of indirect coal liquefaction. The CEU evaluation results show that SFT418 catalyst exhibits excellent catalytic performance for F-T synthesis, under the optimized commercial conditions the CO conversion is more than 92% and the selectivity to C3+ hydrocarbons reaches more than 93%, indicating that the catalyst is ready to be used commercially.
