摘要:

蒽醌法过氧化氢的生产工艺中广泛使用活性氧化铝作为蒽醌降解物的再生剂,活性氧化铝的寿命较短,失活后形成大量固体废物,是困扰过氧化氢生产企业的难题。采用焙烧、浸渍等方法,可以实现废弃活性氧化铝的重复利用,有效减少固体废物的产生量。废弃活性氧化铝也可以作为铝源生产水处理剂、α-氧化铝等产品。概述了近几年过氧化氢生产行业中废弃活性氧化铝回收利用的研究报道,总结了废弃活性氧化铝的组成、再生工艺的改进及回收生产其他产品的研究进展。

Abstract:

In the production of hydrogen peroxide by anthraquinone process,activated alumina is widely used as the regenerant of anthraquinone degradation products.However,activated alumina is easily deactivated and a large amount of solid waste is formed,which is a difficult problem for hydrogen peroxide production enterprises.By calcination and impregnation,the waste activated alumina can be reused and the amount of solid waste can be reduced effectively.The waste activated alumina can also be used as aluminum source to produce water treatment agent,α-alumina and other products.The research reports on the recovery and utilization of waste activated alumina in hydrogen peroxide production in recent years were reviewed,and the advances in the composition of waste activated alumina,the regeneration process and the recovery of alumina to produce other products were summarized.

Key words: waste activated alumina, alumina recycling, alumina regeneration, anthraquinone degradation regenerant
