成型活性炭的制备研究进展

The Advance of Research on Formed Activated Carbon Preparation

目前活性炭产品主要是粉末活性炭。粉末活性炭堆密度低、不易储放、运输和回收,容易造成粉尘污染。成型活性炭克服了粉末活性炭的以上缺点,并可通过加工获得需要的外形,有着更为广阔的应用领域。成型活性炭已成为国内外研究热点。综述了成型活性炭的性能、应用和制备方法,并对其性能影响因素进行了分析。

At present, the powder activated carbon takes the most part of activated carbon production. Powder activated carbon has a low bulk density,thus there are many inconveniences in the storage, transportation and recycle. Further more,it may cause dust pollution. Formed activated carbon has no these disadvantages, and it is also can be easily machined into the shapes needed, so it has a wider fields of application. Formed activated carbon has become the focus of researches at home and abroad. This paper summarizes the performance, utilization and preparation of formed activated carbon,and also analyzes the factors that influence the properties.
