Abstract

Polyoxometalates (POMs) possess unique strong Brønsted acidity. However, little attentions were paid to the effect of POMs with respect to the hydrocracking. Herein we show that Wells-Dawson type POMs Cs5.5H0.5P2W18O62 (CsDP) combined with conventional Fischer-Tropsch catalyst Co/Al2O3 forming a highly efficient bifunctional catalyst for the direct production of clean gasoline from syngas. The Brønsted acidity of the CsDP results in hydrocracking of the heavier hydrocarbons formed on Co/Al2O3. The selectivity for the gasoline product could reach 48.8%, which has increased by 129% than that of conventional FTS catalyst. Furthermore, the catalytic performance of Wells-Dawson type POMs Cs5.5H0.5P2W18O62 and Keggin type POMs Cs2.5H0.5PW12O40 based catalyst is compared. The former exhibits higher CO conversion and C5-C12 selectivity than those of the Keggin type of Cs2.5H0.5PW12O40.
