| 摘 要： | 研究制备过程对丙烷选择氧化制丙烯酸所用MoVTeNbO复合金属氧化物催化剂晶相的形成及其催化性能的影响。最优的干燥方法是用旋转蒸发仪进行干燥,该方法有利于有效晶相的形成和杂质相的抑制。最佳的催化剂焙烧气氛是氩气。X射线衍射分析结果表明,在采用溶液法制备、旋转蒸发干燥温度为60℃、pH值为4.0、氩气为保护气、煅烧温度为600℃等条件下,可获得MoVTeNb复合金属氧化物催化剂。当该催化剂的MoVTeNb摩尔比为 1.0:0.3:0.23:0.12时具有最高的催化活性。

| Abstract: | The effects of the preparation procedure on the formation of crystal phases and catalytic performance of the MoVTeNbO mixed metal oxide catalysts in selective oxidation of propane to acrylic acid were investigated. The results show that the preferred drying method is the rotavapor method, which favors the formation of an effective crystal phase and suppresses the formation of impurity phases. The preferred calcination atmosphere is an Ar atmosphere. The MoVTeNb mixed metal oxide catalysts can be obtained by... |
