一、前言自五十年代中期气相色谱法用于催化研究以来,短短的二十多年不论在理论上或实验技术上都发展得十分迅速,除晶体性质以外,催化剂的宏观性质,表面性质以及反应性能都可以用它进行研究。催化剂的宏观性质是催化剂的基本性质之一,经典的静态容量吸附法是研究它的标准方法,不足之处是操作费时,采用色谱法可克服这个不足,而其准确 I. INTRODUCTION Since the mid-1950s, when gas chromatography was used for catalysis, the short period of more than 20 years has developed rapidly both theoretically and experimentally. In addition to its crystalline nature, the macroscopic and surface properties of the catalyst As well as the reaction performance can be used to study it. The macroscopic nature of the catalyst is one of the basic properties of the catalyst, the classical static capacity adsorption method is to study its standard method, the disadvantage is the time-consuming operation, the use of chromatography to overcome this shortcoming, and its accurate
