化学吸附仪在催化剂研制过程中的应用

Application of the Chemisorption Instrument in Process of New Catalyst Development

化学吸附仪具有多种表征功能 ,能够对新鲜催化剂进行TPD、TPR、TPS、TPSR、单点BET等研究 ,也可对失活催化剂、干燥催化剂进行TPO研究。利用化学吸附仪中的脉冲吸附技术还可对催化剂的酸性、表面金属分散度、金属与载体的相互作用等进行研究。这些分析方法的使用 。

The Chemisorption Instrument has a multifunction of characterizations. It can be used to study fresh catalysts for temperature-programmed desorption (TPD), reduction (TPR), sulphurization (TPS), surface reaction (TPSR), single-point BET surface area, and also to study spent catalysts or dry catalysts for Temperature-programmed oxidation (TPO). In addition, its pulse chemisorption function can provide valuable information about surface acidity, surface metal dispersion and the interaction between metal and support. The application of these analysis methods is of great importance in catalyst development.
