以 SiO 2(SBA-15、MCM-48和 SiO2)和 TiO2-SiO2(MTS-9)介孔分子筛为载体负载8% WO3合成钨基催化剂，研究载体对丁烯歧化制丙烯性能的影响以及载体对丁烯转化率和丙烯选择性的影响。以 SBA-15、MCM-48和 SiO2为载体时，催化剂的丁烯转化率在30%~37%；以 MTS-9为催化剂载体时，丁烯的转化率高达到37%~42%。对所有使用的催化剂进行多种技术表征。结果表明，活性组分在各种载体上的分散度不同，载体 MTS-9具有更好的分散能力，表面活性物种数量最多，催化剂 WO 3/ MTS-9的歧化性能最佳。

The catalysts with SBA-15, MCM-48, SiO2 , and MTS-9 as supports were synthesized with 8% WO3 , and their catalytic performance for metathesis of butene to propene were carried out. The conversion of butene is 30% ~ 37% on the catalysts with SBA-15, MCM-48, and SiO2 as supports, and that of butene is 37% ~ 42% on WO3 / MTS-9 catalyst. The catalyst characterization results show that the catalytic activities depend on the acidic numbers of catalysts prepared and the distribution of tungstens on the supports used. As a result, the performance of 8% WO3 / MTS-9 catalyst for the titled reaction is best.
