| 摘 要： | 以磷酸锆为载体,负载不同类型金属氧化物制备了系列MOx/ZrP催化剂,即FeO_x/ZrP、CoO_x/ZrP、NiO_x/ZrP、NbO_x/ZrP、CuO_x/ZrP、MoO_x/ZrP和WOx/ZrP,并采用XRD、FT-IR、SEM、EDS、TEM、NH3-TPD和N2吸附-脱附等对催化剂进行表征,结果表明,金属氧化物的负载对磷酸锆载体的微观形貌、孔结构以及酸性质等均产生了显著影响。将MOx/ZrP催化剂用于甘油脱水制丙烯醛反应,结果表明,金属负载质量分数为5%的WO_x/ZrP催化剂反应效果最好,甘油转化率达93%,且丙烯醛选择性为82%。

| Abstract: | A series of MOx/ZrP catalysts were prepared by loading different types of metal oxides on zirconium phosphate as the catalyst support,including FeOx/ZrP,CoOx/ZrP,NiOx/ZrP,NbOx/ZrP,CuOx/ZrP,MoOx/ZrP and WOx/ZrP.The as-prepared catalysts were characterized by XRD,FT-IR,SEM,EDS,TEM,NH3-TPD and N2 adsorption-desorption techniques.The characterization results showed that the loading of metal oxides had apparent effects on the morphology,pore structure and acid properties of zirconium phosphate support.The catalysts were employed for the dehydration of glycerol to acrolein.It was found that WOx/ZrP catalyst with 5wt% metal loading exhibited the best catalytic effects,and glycerol conversion of 93% and the selectivity to acrolein of 82%were attained. |
