随着气相色谱技术的发展,采用气相色谱法测量吸附和比表面,得到了各方面的广泛重视。色谱法不但设备简单,操作方便、快速,而且可在催化剂操作条件下进行测量,这更是经典方法远所不及的。在催化剂操作条件下或催化反应过程中测得的这些参数,对解释表面催化反应机理,最后了解催化过程不但十分有用,而且是非常必须的。这方面的内容也就是本文的重点。

With the development of gas chromatography technology, gas chromatography has been used to measure the adsorption and specific surface area, and has gained wide attention in all aspects. Chromatography not only equipment is simple, easy to operate, fast, and can be measured under the conditions of the catalyst, which is far beyond the classical method. These parameters, measured under the catalyst operating conditions or during the catalytic reaction, explain the surface catalytic reaction mechanism and finally it is not only useful but also very necessary to understand the catalytic process. This aspect of the content is the focus of this article.
