La_2O_3催化丙烷脱氢反应的研究

Study of Dehydrogenation of Propane over La_2O_3 Catalyst

本文运用TPD－MS、IR、XRD、DTA－TG等技术对La2O3表面的酸碱性和氧活性、表面羟基、晶体结构等性质进行了研究．并与在流动态微型反应器装置上的丙烷脱氢反应的性质进行了关联，发现La2O3表面的碱中心和吸附氧的活性对该反应有较大的催化作用。

The properties of surface acidity-basicity,oxygen mobility,surface hydroxy,crystal structure of LaO3, are studied by means of TPD-MS. IR, XRD and DTA-TG, etc. The properties of the re action of dehydrogenation of propane in flow mic-reactor are connected with the properties of La2O3. The results show that surface basicity and oxygen mobility play a relatively important role in this reaction.
