摘  要：
利用浸渍法制备了Cu负载于不同介孔材料的高分散催化剂,并通过透射电子显微镜(TEM)、X射线衍射(XRD)和N_2物理吸附分析仪确认催化剂的结构特征和形貌。XRD图谱证明了Cu/MCM-41和Cu/Al2O3催化剂存在CuO、Cu/CMK-3存在Cu_2O和CuO;TEM显示了催化剂内部结构和表明了纳米粒子已担载于介孔载体上。通过反应釜作为低压机械搅拌淤浆床评估了几种催化剂在1,4-丁炔二醇合成反应中的催化性能,结果表明:与Cu/MCM-41和Cu/CMK-3催化剂相比,Cu/Al_2O_3不仅转化率高达86.2%,稳定性也较好,表明Al_2O_3作为载体在1,4-丁炔二醇合成工业中具有良好的应用前景。

摘  要：
Highly dispersed copper-based catalysts were prepared by impregnating copper components onto mesoporous materials. The obtained catalysts were characterized by Transmission Electron Microscopy(TEM), X-ray diffraction(XRD), and N_2 physical adsorption analyzer. XRD patterns showed the presence of CuO phase for Cu/MCM-41 and Cu/Al_2O_3 catalyst, and showed the presence of Cu_2O and CuO phase for Cu/CMK-3 catalyst. TEM results showed that the internal structure of the catalyst and the nanoparticles were located on the mesoporous carriers. The performances of catalysts for 1,4-butynediol synthesis were evaluated through the reactor. The results indicated that compared with Cu/CMK-3 and Cu/MCM-41 catalysts,Cu/Al_2O_3 catalyst indicated better conversion of 86.2% and selectivity towards 1,4-butynediol. Al_2O_3 as a carrier has development prospects for 1,4-butynediol synthesis in industrial application.
