摘要
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.关键词
