| Abstract: | TiO2-SBA-15 Zeolite was prepared by incipient wetness impregnation and excessive impregnation. The property of adsorptive desulfurization of TiO2-SBA-15 was evaluated with FCC petrol via the static adsorption experiment in a batch-wise reactor. The results showed that the highly crystalline anatase TiO2 of the adsorbent prepared by excessive impregnation dispersed better on the surface of SBA-15. The surface area of the adsorbent prepared by excessive impregnation were larger. The desulfurization rate of TiOR-SBA-15 could reach 42.54% at the calcination temperature of 500 ℃ and the TiO2 loading of 20%. After 3 times roasting regeneration,the desulfurization rate was still at about 35%. |
