Enhancing the Fischer–Tropsch Synthesis Activity of Co-based Catalysts by Adding ZrOx to the SiO2 Support and Chelating Ligands to the Co-precursor

Co/ZrO x /SiO 2 catalysts with enhanced dispersion of Co 0 and turnover frequency were successfully prepared combining two different promotion effects, i.e., modifications of SiO 2 surface with ZrO x by liquid phase deposition and influencing coordination structure of Co species using chelating agents or glycols. The catalysts exhibited ~6.3-fold higher CO conversion than Co/SiO 2 and those promoted by organic additives or ZrO x alone, indicating activity enhancement was induced by cooperation of these two promoters.
