摘要:      采用后合成法制备Nb-SBA-15分子筛吸附剂,经X-射线衍射(XRD)、N2吸附-脱附测试手段表征,结果表明,Nb-SBA-15虽表面积、孔容、孔径略有下降,但仍保持良好的介孔结构。以其为吸附剂,模拟油为原料,采用静态吸附法进行脱硫实验。结果表明,最佳脱硫条件为:铌酸与载体质量比1∶10,吸附时间30min,吸附温度120℃,剂油质量比1∶20。在此条件下,脱硫率达31.30%,饱和吸附量599μg/g。

Abstract: Niobic acid/SBA-15 molecular sieve was prepared by impregnation method, and characterized by XRD and BET. The results show specific surface area, pore volume and pore diameters of the sample slightly decreased; however, mesoporous structure was well preserved. Its desulfurization performance from model oil was studied by static adsorption method. The results show that the sulfur removal rate can reach 31.30% and saturation adsorption capacity was 599 μg/g under the following optimum conditions: niobic acid/support 10wt%, adsorption temperature 120 ℃, time 30 min and catalyst/oil weight ratio 1∶20.
