氯对钌基氨合成催化剂的影响

氯离子的脱除是制备高性能钌催化剂的一个重要步骤。本文综述了新型钌基氨合成催化剂制备过程中的脱氯环节。介绍了以RuCl₃·3H₂O作为活性前驱体的钌催化剂中氯离子的来源、氯在催化剂中的存在方式、它对催化剂的毒害作用以及去除氯离子的方法。

The Effect of Chloride Ion on Ruthenium Supported Catalyst for Ammonia Synthesis

Ruthenium catalyst is considered as a new type catalyst for ammonia synthesis after the classical iron fused catalyst.Chloride ion is a poison to the catalyst.This article summarizes the source of the chloride,its state in the catalyst,poisoning effect to the catalyst and the method to remove chloride.It is one of the key points to achieve high catalytic performance for ammonia synthesis.
