【摘要】 利用共沉淀法使铁和铅的硝酸盐在NH₄OH作用下生成氢氧化物沉淀,经过过滤、干燥和煅烧得到了Fe₂O₃—PbO无硫无铬一氧化碳中温变换催化剂。通过对不同含铅量催化剂样品的活性测定,得到该催化剂最佳铅含量为12％（重量百分比）,并且其活性高于某厂定型生产的无硫LHB—103型Fe₂O₃—Cr₂O₃催化剂。更多还原

【Abstract】 Fe₂O₃—PdO catalyst （sulfur—free and chromium—free） for the medium temperature shift reaction of carbon monoxide was prepared by ppty., Fe and Pb nitrates reacting with NH₄OH and their product hydroxides filtered, dried and calcined. The optimum Pb content of 12 wt% in this catalyst was found by determing the activities of several other catalyst samples which contained different per cent weight of lead. This catalyst showed higher activity than the LHB-103 sulfur—free catalyst produced by Liaohe Chemical Fertilizer Factory.更多还原
