N2 - A systematic study was carried out on the preparation and application of metal-loaded polypropylene-divinyl benzene resin for dibenzothiophene adsorption. Amidoxime groups over used industrial polypropylene-divinyl benzene chelating resin were regenerated through a chemical graft reaction, and the highest regeneration efficiency of about 90 % can be reached. Different metal phases (Zn, Ni, Cu, Fe, Bi, and Ag) were introduced to the regenerated resin via an incipient-wetness impregnation method to examine their desulfurization efficiency. The desulfurization efficiency of ca. 86.3 % can be gained over Zn-loaded resin (Zn-R) under optimized reaction conditions. The order of different desulfurization influencing factors was further verified according to the orthogonal experiments, that is, desulfurization temperature > metal loading content > space velocity > organic sulfur concentration. Distribution of adsorption products was analyzed, and the results reveal that the metal-modified resins can effectively remove the organic sulfur compounds in diesel oil without loss of its octane value. The desulfurization effect of metal-contained resins is primary determined by the π-complexation.
