研究了一些锂基氧化物对异丁烷的催化氧化脱氢作用，其中Ｌｉ２ＳｎＯ３显示出优良的催化性质，Ｌｉ２ＭｎＯ３，ＬｉＦｅ５Ｏ８和ＬｉＡｌ５Ｏ８对异丁烯的选择性较差，而Ｌｉ２ＣｅＯ３，ＬｉＦｅＯ２和ＬｉＺｎＯ２在反应条件下不稳定。系列ＬｉＳｎＯ催化剂的ＣＯ２ＴＰＤ分析表明，当ＳｎＯ２转化为Ｌｉ２ＳｎＯ３时，在表面形成了碱中心，它有利于异丁烯从催化剂表面脱附。Ｏ２ＴＰＤ和Ｈ２ＴＰＤ结果表明，此时吸附的氧物种数量降低，异丁烯的深度氧化受到抑制。Ｌｉ２ＳｎＯ３中晶格氧物种的活性对异丁烷催化氧化脱氢可能是适宜的，但不利于深度氧化。 Li 2 MnO 3, Li 2 MnO 3, LiFe 5 O 8 and LiAl 5 O 8 have poor selectivity to isobutylene, while Li 2 CeO 3, LiFeO 2 and LiZnO 2 have good catalytic performance in the reaction of Unstable CO2 -TPD analysis of the series of Li-Sn-O catalysts showed that when SnO2 was converted to Li2SnO3, an alkali site was formed on the surface, which facilitated the desorption of isobutene from the catalyst surface. The results of O2-TPD and H2-TPD showed that the amount of oxygen species adsorbed at this time decreased and the depth oxidation of isobutene was inhibited. The activity of lattice oxygen species in Li2SnO3 may be suitable for the catalytic oxidative dehydrogenation of isobutane, but not for deep oxidation.
