催化氧化活性炭法净化磷化氢熏蒸尾气综述

摘要

在磷化氢进行熏蒸保护粮食、烟草仓储过程中，会产生有剧毒的磷化氢熏蒸尾气，对周围人和环境产生重大影响，催化氧化活性炭是解决这一问题最有效的方法之一。简述了历来磷化氢气体净化技术的优缺点，较详细的论述了催化氧化活性炭净化磷化氢工作原理、处理工艺及再生方法。%In the process of fumigation with phosphine for protecting food and tobacco in store,highly toxic exhausted gas containing phosphine is likely to be produced,which may produce significant im-pact on the surrounding environment. Catalytic oxidation activated carbon is one of the most effective ways to solve this problem. The paper mainly introduces the advantages and disadvantages of tradi-tionally phosphine gas purification technology ,with more detailed discussion on the principles of work,treatment process and regeneration methods for catalytic oxidation activated carbon purification of phosphine.
