摘要
大量工业废催化剂的丢弃,不仅是一种资源的浪费,而且对环境也会造成一定程度的污染,针对工业废催化剂的回收利用进行了探讨,着重介绍了几种工业废催化剂的综合回收技术。
In production process of Catalyst, in order to guarantee its activeness, the selectivity, the defense against toxicity, the presence of certain performance indicators, such as intensity and longevity, we frequently choose some non -ferrous metals even precious metals as principal components. Although in the using process of the catalyst, its shapes, the structure and the quantity of certain components can change,there still exist the quite quantity, the non- ferrous metal or the precious metal in the spent catalyst. Sometimes their content can be far higher than the corresponding component of content -barren ore, the massive abandonment of industrial spent catalyst, creates pollutions to the environment in some is not only one kind of resources waste, but also can degree . This article carries on the discussion in view of the industry spent catalyst＇ s recycling use, emphatically introduced several synthetic recycling technologies of industrial spent catalyst.
