分别以合成的APO-5,SAPO-5或市售ZSM-5为载体,Co3O4,MoO3或TiO2为活性组分,制备了一系列负载型催化剂,利用X射线粉末衍射仪、扫描电子显微镜、全自动比表面积及孔隙分析仪、NH3程序升温吸附-脱附分析仪、傅立叶变换红外光谱仪等对上述催化剂进行表征,并考察其催化苯-乙醇烷基化反应的性能。结果表明:TiO2和SAPO-5分别适合作催化剂的活性组分与载体,在TiO2与SAPO-5的质量比为0.20、反应温度为250 ℃、反应时间为1 h和反应压力为1 MPa 的优化条件下,乙醇转化率为99%,乙苯收率为84%。
- Abstract:
-
A series of supported catalysts were prepared by using synthetic APO-5, SAPO-5 or commercial ZSM-5 as carriers, Co3O4, MoO3 or TiO2 as active components, respectively. The catalysts were characterized by X-ray powder diffractometer, scanning electron microscope, automatic specific surface area and pore analyzer, NH3 temperature-programmed adsorption and desorption analyzer and Fourier transform infrared spectrometer, and their catalytic performance for benzene-ethanol alkylation reaction were investigated. The results showed that TiO2 and SAPO-5 were suitable as the active component and carrier of the catalysts, respectively. Under the optimized conditions of mass ratio of TiO2 to SAPO-5 of 0.20, reaction temperature of 250 ℃, reaction time of 1 h and reaction pressure of 1 MPa, the conversion of ethanol was 99% and the yield of ethylbenzene was 84%.
