摘　　要：针对直接法生产有机硅单体所产生的废触媒存在污染重、回收难等现状,本文利用激光粒度仪、ICP及SEM等设备技术,对废触媒的成分、含量、形貌及粒度进行了系统的分析研究。研究发现,废触媒中铜元素含量高,具有较高的回收价值。此外,硅粉和金属颗粒的粒径都很小,分布在一个较小的区域,需要利用萃取-反萃取循环处理技术才能有效脱除重金属。本研究为实现废触媒有效成分的回收利用、提高企业效益和减少环境污染提供了理论指导。In view of the present situation of heavy-metal pollution and difficult recovery of abandoned catalyst produced by direct production of organosilicon monomer,the composition,content,morphology and particle size of abandoned catalyst were systematically analyzed and studied by using laser particle size analyzer,ICP and SEM.It is found that the abandoned catalyst has a high content of copper and has a high recovery value.In addition,the particle size of silica powder and metal particles is very small and distributed in a small area,which requires the extraction-reverse extraction cycle treatment technology to effectively remove heavy metals.This study provides theoretical guidance for realizing the recycling of active components of abandoned catalyst,improving enterprise benefits and reducing environmental pollution.
