| 摘 要： | 在氢氧混合体系中，沉积-沉淀法制备的Ag/TS-1催化剂对丙烯环氧化反应具有高的催化活性和选择性。本文主要考察了载体TS-1的硅钛比和反应温度对催化剂性能的影响。结果表明：当载体TS-1硅钛比为64，反应温度150℃时，2wt%Ag/TS-1催化剂表现出优异的催化性能，丙烯转化率和环氧丙烷选择性可分别达1.37%和93.51%。

Highly Effective Propylene Epoxidation with Hydrogen-Oxygen Mixture over Ag/TS-1 Catalysts |
| |
| Abstract: | Propylene oxide (PO) is one of the most important chemical feedstocks for producing polyether polyol polymers such as polyurethane. Commercially, PO is manufactured by either chlorohydrin or co-production (Halcon) route. The chlorohydrin route generates chlorinated by-products, mainly dichloropropane and CaCl2. The co-production route is capital intensive and its economics is linked to the economic fortunes of the by-products, namely styrene or tert-butyl alcohol. |
