摘要
本文用等体积浸渍法制备了一系列Pt-Pd/γ-Al2O3催化剂,并考察载体预焙烧和MgO改性对其催化氧化性能的影响.结果表明:γ-Al2O3载体经高温预焙烧和MgO改性后.其表面碱性增强,并影响催化剂活性中心在表面的分布,从而使催化剂对正丁醇、苯和正已烷三种有机物的深度氧化活性有不同程度的提高.其中以正己烷最为显著。
Effect of pre-calcination and MgO modification of γ-Al2O3 support on the oxidation activities of Pt-Pd catalysts was investigated.The results indicated that the pre-calcination and/or MgO modification of γ-Al2O3 supKport could obviously increase activities a small extent for the oxidation of n-butanol.
