摘要:

以分子筛和稀土金属化合物为活性组分，与一定比例的γ-氧化铝载体混合后制成脱烯烃催化剂，以此取代污染严重的白土来脱除芳烃中的微量烯烃。本研究考察了该催化剂的活性和寿命，并利用红外光谱法对催化剂表面的固体酸中心分布情况进行了研究。

Abstract:

In this paper, zeolite and added metal compounds had been used as the active components and alumina had been used as the carrier to prepare a new catalyst. This new catalyst can be used to remove trace olefins from aromatic hydrocarbons instead of polluta
