摘要
炼厂加氢处理废催化剂每年产生量巨大、增长迅速,且污染环境,如何对其进行有效的综合利用在近年来受到了人们的广泛关注。本文从炼厂加氢处理催化剂失活后的再生、低活性废催化剂在其它装置上的再利用以及从废催化剂中回收或生产有价材料等方面阐述了炼厂加氢处理废催化剂的综合利用方法,并对其目前存在的不足和将来的发展方向进行了探讨。
The efficient comprehensive utilization of spent hydrotreating catalysts in refinery has received considerable attention because of its increasing enormous quantity and contaminating the environment. In this paper,the progress in utilization of spent hydrotreating catalysts is summarized from three points of regeneration and recycling,reuse of spent hydrotreating catalysts in other processes and the preparation or recycling of useful materials from the spent catalysts. Besides that,the present imperfections and directions in the future are also propounded.
