Influences of physicochemical properties of ZnO on the adsorptive desulfurization performance of Ni/ZnO adsorbent

摘要

ZnO nanoparticles with high surface area were synthesized by hydrothermal homogeneous precipitation method,and the influences of physicochemical properties of ZnO materials on the adsorptive desulfurization performance of Ni/ZnO adsorbent were investigated.Activity evaluation showed that the Ni/ZnO adsorbent using nanosize ZnO as support materials had better adsorption performance,and the sulfur adsorption capacity was maximized depending on the surface area and particle size of ZnO materials.The thiophene removal efficiency and the breakthrough capacity (10 ppm level) were found to be 100％ and 6.1 (mg of sulfur per g of adsorbent),respectively.
