Abstract: W-SBA-15(x) was synthesized by direct synthesis method using tetraethoxysilane (TEOS) as silica source and Na2WO4 as W source, (x represent the mole ratio of W and Si). The W/SBA-15(x) was prepared by post-synthesis method using prepared SBA-15 and ammonium tungstate solution. The samples were characterized by XRD, BET, and NH3-TPD. Effect of preparation method, WO3 loadings, calcination temperature and time on the performance of adsorptive denitrification was investigated. The results show that the mesoporous structure of SBA-15 can well be remained by both direct synthesis and post-synthesis methods. The ordered crystallinity of W-SBA-15(10) is worse. The denitrification performance of W-SBA-15(20) is better than W/SBA-15(20) and W-SBA-15 (10). The denitrification performance of W-SBA-15(20) is the best when the adsorbent was calcined at 550 ℃ for 6 h. At the adsorption conditions of 140 ℃, 30 min and absorbent/oil ratio of 1:30, the denitrification rate of model oil quinoline solution in dodecane, reaches 66.32% and the saturated absorption capacity is 25.66 mg/g.
