摘　　要：通过程序升温脱附（ＴＰＤ）、程序升温表面反应（ＴＰＳＲ）及脉冲反应（ＰＳＲ）等化学物理技术，综合分析研究了铁系无铬（ＮＢＣ－１）型ＣＯ高温变换催化剂的吸附性能及化学反应特性。研究表明，ＮＢＣ－１型催化剂对Ｈ２Ｏ具有很强的吸附能力，不易吸附ＣＯ及ＣＯ２。By using of some chemical physics technology, such as temperature programmed desorption (TPD), temperature programmed surface reaction (TPSR) and pulsed surface reaction (PSR), this thesis makes a thorough investigation on the adsorption performance and chemical reaction characteristics of the non-chromium iron-based (NBC-1) for CO high temperature shift reaction The results show that the NBC-1 catalyst surface has strong adsorption ability to H2O, weaker adsorption to CO and CO2, and that the Water Gas Shift reaction mechanism on this catalyst is the redoxreaction
