Abstract
A newly kind of spinosus loaded-heteropolyacid catalyst Fe3O4@MOF-PMoW (abbreviated as FeMP, M = Cr, Cu and Zr) has been obtained under one-pot method using the various magnetic MOF materials bases. Detailed characterizations have proved out the spinosus structure, with the stinging surface morphologies outside, which benefits for the excellent desulfurization performance to the larger contact area with sulfur compounds as much as possible. To be noted, the FeCrP catalyst shows the 100% DBT removal in 60 min, while only 97.0% and 91.6% for FeCuP and FeZrP, respectively. The phenomenon is mainly attributed to the larger BET contact area, leading to link more PMoW to react with DBT in oil. In particular, the FeCrP could be applied in ODS process even after 10 times without the obvious decrease in catalytic activity and the same highly desulfurization performance also has founded in real diesel, showing a better using value in actual industrial application.
