利用无氧脉冲技术并结合 FTIR 和 XPS 对丁烷在 V-Mg-O 系催化剂上的氧化行为进行了研究,结果表明:V-Mg-O 系催化剂对丁烷具有互相独立的完全氧化和选择性脱氢两种活性位;当钒含量达一适当比例时,催化剂具有较高的反应活性,证实了正钒酸镁不是这种催化剂的活性组分.本文亦研究了温度对反应的影响,初步探讨了催化剂的结构与其活性间的关系.
Oxidation behavior of butane on V-Mg-O catalysts was investigated by means of anaerobic pulse combined with FTIR and XPS. The results show that the V-Mg-O catalysts have completely independent and complete oxidation and selectivity to butane The results show that magnesium orthovanadate is not the active component of this catalyst.We also studied the effect of temperature on the reaction, Preliminary discussion of the relationship between the structure of the catalyst and its activity.
