Abstract The effects of different preparation methods for Cu/TiO2-Al2O3 catalysts, such as stepwise impregnation method, co-impregnation method, sol-gel method, and co-precipitation method, and activation modes on vapor-phase hydrogenation of maleic anhydride (MA) to g-butyrolactone (GBL) at atmospheric pressure were investigated in this paper. The catalyst prepared by co-precipitation method exhibited higher performance over the temperature range of 180～270°C, in which the conversion of MA and selectivity of GBL was nearly 100% and 93.2%～99.3%, respectively.
Key words Maleic anhydride, Vapor-phase hydrogenation, g-Butyrolactone, Cu/TiO2-Al2O3 catalyst

摘要 研究了不同制备方法(分步浸渍法，共浸渍法，溶胶凝胶法和共沉淀法)和还原方式对用于顺酐常压气相加氢制g-丁内酯Cu/TiO2-Al2O3催化剂性能的影响，并对影响因素进行了初步探讨。结果表明，用共沉淀法制备的催化剂具有较好的催化性能，当反应温度在180～270°C范围内，催化剂的活性和选择性分别为100%和93.2%～99.3%。
