一氧化碳低温氧化催化剂的研究

STUDY ON CATALYST FOR CO OXIDATION AT LOWER TEMPERATURE

在矿井生产中，为防止ＣＯ中毒，一般的防护方法采用自救器、压缩氧和氧气发生器。自救器具有体积小和携带方便等优点仍广泛用于矿井ＣＯ的救护。但由于ＣＯ催化剂催化反应放热大，使工人佩戴时感觉不适，容易造成摘掉自救器而发生危险的情况。研究低温下使ＣＯ高效转化的...

The effects of components and preparation method of catalysts for CO oxidation on activity and stability of the catalyst were investigated in a fixed bed reactor The results show that CuO-MnO/ZrO 2-Al 2O 3 prepared by sedimentary method exhibited very high activity and stability at lower temperature As supporter ZrO 2 increased catalytic activity, whereas the mechanical strength of the catalyst with supporter of ZrO 2 alone was low The catalyst strength can be improved by adding proper amount of Al 2O 3T U D Y O N C A T A L Y S T F O R C O O X I D A T I O N A T L O W E R T E M P E R A T U R E Liu Jianzhou Zhang Sulin Wang Yongzhi Zong Zhimin Wei Xianyong( Departm ent of Energy Utilization and Chemical Engineering China University of mining and Technology Xuzhou) A B S T R A C T The effects of components and preparation method of catalysts for C Ooxidation on activity and stability ofthe catalyst were investigated in a fixed bed reactor The results show that Cu O- Mn O Zr O2 - Al2 O3 prepa
