摘　　要：用溶胶-凝胶法制备了H3PW12O40 /SiO2 -Al2O3 催化剂,并用于二苯并噻吩的氧化-吸附脱除实验,考察了催化剂用量、叔丁基过氧化氢用量、反应温度及反应时间对脱硫效果的影响,得出反应的最佳条件:催化剂用量为1% (w),叔丁基过氧化氢与硫的摩尔比为3,反应温度为70℃,反应时间为3h。该催化剂还能吸附二苯并噻吩的氧化产物砜或亚砜,具有良好的稳定性和再生性。The H_3PW_(12)O_(40)/SiO_2-Al_2O_3 was prepared by a sol-gel method and was used in the oxide-adsorption removal of bisbenzothiazole. The influences of operating parameters such as the amount of catalyst and t-BuOOH, reaction temperature, reaction time on the desulfurization of bisbenzothiazole were investigated. The optimal reaction conditions are catalyst amount(w%) was 1%, the mole ratio of t-BuOOH to sulfur was 3, the reaction temperature was 70℃ and reaction time was 3 hours. The catalyst can adsorb the oxidation products of dibenzothiophene (sulfone or sulfoxide), and had very good stability and regeneration.
