摘要： 研究了Zr添加量对Mo-V-O基催化剂丙烷选择氧化制丙烯醛催化性能的影响.对催化剂的BET、X射线衍射、H2-程序升温还原、NH3-程序升温脱附和异丙醇分解表征结果表明,Zr的添加改变了催化剂的物相结构、氧化还原性和酸碱性质,从而影响催化剂的催化性能,其中Mo2VZr0.5Ox催化剂表现出较好的催化活性和丙烯醛选择性.

Abstract: A detailed study on the promotion effect of Zr on Mo-V mixed oxide catalysts in the selective oxidation of propane to acrolein was performed. The catalysts were characterized by BET, XRD, H2-TPR, NH3-TPD and isopropanol decomposition reaction. The addition of Zr modifies the catalysts phase composition and improves their redox and acid-base properties. As a result, the higher catalytic activity and selectivity were obtained over Mo2VZr0.5Ox catalyst.
