Reactive Adsorption Desulfurization of Dibenzothiophene in Presence of Mesoporous Adsorbents

Abstract

Reactive adsorption desulfurization of a model fuel containing dibenzothiophene with various adsorbents was studied. Adsorbents based on MCM-41 mesoporous material with supported Ni and ZnO phases were prepared and characterized. The desulfurization activity of the material in a fixed-bed flow-through reactor was compared to that of alumina-based adsorbents. The adsorbent based on MCM-41 considerably surpasses its analog on Al2O3 support in the adsorption capacity in reactive adsorption desulfurization of dibenzothiophene at 350°С, pressure of 2 MPa, and feed space velocity of 1 h–1.
