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.

介孔吸附剂存在下二苯并噻吩的反应吸附脱硫

摘要

研究了含有二苯并噻吩的模型燃料与各种吸附剂的反应吸附脱硫。制备并表征了基于 MCM-41 介孔材料的具有负载 Ni 和 ZnO 相的吸附剂。将该材料在固定床流通式反应器中的脱硫活性与氧化铝​​基吸附剂的脱硫活性进行比较。基于MCM-41的吸附剂在350°С、2 MPa压力和1 h ^–1进料空速下的二苯并噻吩反应吸附脱硫中的吸附能力大大超过其在Al ₂ O ₃载体上的类似物。
