制备一个性能良好的催化剂,首先要选择适当的催化剂组成。但在催化剂的化学组成确定以后,催化剂的制备方法往往对其活性、选择性和稳定性有着很大的影响。浸渍法是催化剂制备方法之一,该法操作简单,且活性组元容易分布在反应物分子可以到达的担体表面,从而提高了活性组元的利用率,因而应用较广。 Preparation of a good performance of the catalyst, we must first select the appropriate catalyst composition. However, after the determination of the chemical composition of the catalyst, the preparation of the catalyst often has a great impact on its activity, selectivity and stability. The impregnation method is one of the preparation methods of the catalyst. The method is easy to operate, and the active component is easily distributed on the surface of the support that the reactant molecules can reach, so as to improve the utilization ratio of the active component, thereby being widely used.
