用于Deacon反应的Ru基催化剂的研究现状

Recent Progress on Ruthenium-Based Catalysts for Deacon Reaction

化工原料氯的大量使用以及氯原子在众多涉氯化工过程中的利用率很低,导致副产氯化氢的产生量显著增长,制约该行业的发展。Deacon反应是一个低能耗、高效率、环境友好可解决大量副产氯化氢的有效途径,其中Ru基催化剂由于活性高、使用寿命长的优势,是目前唯一的氯化氢催化氧化制氯的商品化催化剂。但是,Ru基催化剂也存在成本高和投资大的缺点,如何降低Ru基催化剂的成本,仍是未来需要重点研究的方向。本文主要综述了用于Deacon反应的Ru基催化剂最新的研究进展,介绍了Ru基催化剂的反应机理、性能改进及回收方法,并对其今后的发展方向作了展望。

Due to the large use of chemical chlorine and the low utilization rate of chlorine atoms in the chlorination process, the amount of hydrogen chloride as the by-product has increased significantly, restricting the development of the chemical industry. Deacon process is a low-energy, high-efficiency, environmentally friendly and effective way to solve a large amount of by-product hydrogen chloride. Among them, ruthenium-based catalysts are the only commercial catalysts for the oxidation of hydrochloric acid to chlorine due to their high activity and long service life. However, ruthenium-based catalysts also have the disadvantages of high-cost and large investment. How to reduce the cost of Ru-based catalysts is still a research direction that needs to be focused in the future. This review mainly summarizes the latest research progress of Ru-based catalysts for deacon reaction, including the reaction mechanism, performance improvement and recovery methods. The final section of this review paper also proposes the future prospects for Ru-based catalysts.
