摘要
采用微波加热草酸盐共沉淀法制备了一系列M-Fe-O(M=V、Cr、Mn、Co、Ni、Cu、Zn)催化剂,考察了其对丙烷氧化脱氢制丙烯反应的催化性能,并对催化剂进行了BET、XRD、H2-TPR、电导测量等表征.实验结果表明V-Fe-O和Cr-Fe-O催化剂表现出较好的丙烷氧化脱氢制丙烯催化性能.反应温度为873 K时,以V-Fe-O为催化剂时丙烷转化率34.46%,丙烯选择性30.91%;在Cr-Fe-O为催化剂上丙烷转化率36.31%,丙烯选择性34.22%.
A series of M-Fe-O （M = V, Cr, Mn, Co, Ni, Cu, Zn） catalysts were prepared by oxalate co-precipitation method with microwave heating and characterized by X-ray diffraction （XRD）, BET specific surface, H2- TPR and conductivity measurement. Their catalytic performance for the oxidative dehydrogenation of propane to propene had been investigated. It was found that the M-Fe-O （ M = V, Cr） catalysts showed higher catalytic activity for propene formation. At 873 K, 34.46% C3Hs conversion and 30.91% C3H6 selectivity over V-Fe-O catalyst, 36.31% C3H8 conversion and 34.22% C3H6 selectivity over Cr-Fe-O catalyst were obtained respectively.
