氯化氢催化氧化制氯气的研究进展
|
Abstract:
在众多涉氯化工过程中，氯原子利用率较低，导致产生大量副产氯化氢制约行业发展。氯化氢催化氧化循环制氯气，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。本文综述了Deacon催化剂的发展历程，以及不同Deacon催化剂的作用机理。虽然Ru基催化剂已在工业上实现大规模应用，但是如何提高催化剂稳定性，和降低催化剂成本，仍是未来需要重点研究的方向。
In many chlorine-related chemical processes, the low utilization of chlorine atoms with a large amount of hydrogen chloride as the by-product restricts the development of the chemical industry. Therefore, how to efficiently recover chlorine resources is an urgent issue for the chlorine-related industry. The catalytic oxidation of hydrogen chloride into chlorine, as the Deacon process, is an ef-fective way to solve this issue with low energy consumption, high efficiency and environmental friendliness. In this paper, the development of Deacon catalysts is reviewed, and their reaction mechanisms are also discussed. Ru-based catalysts have been used on a large scale in industry, but how to improve catalyst stability and reduce catalyst cost is still the key research direction for the future.
