Abstract: A proprietary catalyst for slurry Fischer-Tropsch (F-T) synthesis was developed by China Shenhua Coal to Liquid and Chemical Company and it was applied firstly in a newly built indirect coal liquefaction unit with a capacity of producing 180 thousand tons oil per year. The whole operation was successful and qualified light oil, heavy oil, heavy wax and synthetic water were produced. The transfer of activated catalyst from pretreatment unit to F-T synthesis unit and the online substitution of fresh catalyst for deactivated catalyst were conducted successfully. During the second run, the plant kept stable operation for 1 113 h continuously, and the results showed that the performance of SFT418 catalyst could well meet the demands of industrial operation: the space-time yield of C5+ reached 1.0 t/t cat·h, CO2 selectivity was less than 20 mol%, CH4 selectivity was in the range of 1.5-3.5 mol% and the iron content of refined heavy wax was less than 5 ?g/g.
