吸附現象在自然界中極为普遍,同时在生产中也日益得到更广泛的应用。任何一种多相过程都要经过表面反应阶段。如果相与相之間的界面扩展得很强烈,那么这个阶段也就具有特殊重要的意义。在气体和液体中所进行的吸附过程,被广泛地用来净化气体和液体,去除各种有害的杂質,提取有用的杂質,以及用于混合物的色層分离。在催化剂表面上發生吸附以及与催化剂表面發生化学作用,是多相催化作用的两个最重要的反应阶段。大量的高分散体被用做填料。这类分散体与介質之間的关系,可以通过使它們的表面
Adsorption phenomenon is extremely common in nature, but also increasingly more widely used in production. Any multi-phase process must go through the surface reaction stage. If the interface between phases grows strongly, then this phase is of special importance. Adsorption processes carried out in gases and liquids are widely used to purify gases and liquids, remove various harmful impurities, extract useful impurities, and provide chromatographic separation of the mixture. Adsorption on the catalyst surface and chemical interaction with the catalyst surface are the two most important reaction stages for heterogeneous catalysis. A large number of high dispersions are used as fillers. The relationship between such dispersions and the media can be made by making their surfaces
