沉淀剂对CuO/CeO2催化剂织构性质及CO催化氧化性能的影响
The Effect of Precipitators on the Texture Properties and CO Catalytic Oxidation Performance of CuO/CeO2 Catalysts
摘要
Abstract
Catalysts CuCe-OH and CuCe-CO3 were prepared by hydrothermal method using KOH and K2CO3 as precipitating agents.The catalyst was characterized by XRD,BET,H2-TPR and TG-DTA,and its CO catalytic oxidation performance was evaluated by a fixed bed reactor.The results show that the type of precipitator not only has a great influence on the texture properties of the catalyst,but also determines whether the CuCe catalyst without heterocrystalline phase can be successfully prepared.The specific surface areas of CuCe-OH and CuCe-CO3 catalysts were 96.5 m2/g and 17.3 m2/g,respectively.Under the evaluation conditions of 60 000 mL/(g·h),CO volume fraction of 0.6%,O2 volume fraction of 1.5%,Ar volume fraction of 97.9%,CuCe-OH catalyst showed good catalytic activity,and CO conversion reached 99.0%at 140℃.关键词
