黄磷尾气深度净化技术研究现状及展望

Research Status and Prospect in Deeply Purified Technology of Yellow Phosphorus Exhaust

摘要: 本文综述了黄磷尾气净化及深度净化的技术现状，介绍了吸收法、吸附法、催化氧化法等净化方法。其中，催化氧化法具有操作简单、净化效率高、催化剂易再生等优点，存在潜在的应用价值。基于此原理开发的黄磷尾气深度净化技术可以有效脱除残存的杂质，净化后的尾气可作为普通的工业原料使用，但对于催化剂中毒、再生的问题研究还不够深入。针对黄磷尾气深度净化技术应用中存在的实际问题，结合现有研究，展望了其应用前景。

Abstract: The research status about purifying impure components of yellow phosphorus exhaust was inves-tigated in this paper. The purification methods such as absorption, adsorption and catalytic oxida-tion are introduced. And the catalytic oxidation method has advantages of simple operation, high purification efficiency and easily reproducing the catalyst, meanwhile it has potential values in practical application. Based on these principles, deeply purified technology of yellow phosphorus exhaust can effectively remove residual impurities. And the purified exhaust can be used as ordi-nary industrial raw materials, but there is few deep research on catalyst poisoning and regenera-tion. In view of the practical problems existing in the application of the deeply purified technology of yellow phosphorus exhaust, we combined them with the existing researches and looked forward to the prospect of its application.
