在Ar气流中热处理KOH-煤焦制大比表面积活性炭

PREPARATION OF HIGH SURFACE AREA ACTIVATED CARBON THROUGH HEAT TREATMENT OF COAL CHARKOH UNDER Ar FLOW

本文将煤焦与ＫＯＨ混合，在Ａｒ气流中进行低温、高温二次热处理，制得了比表面积为２９１８ｍ２／ｇ的活性炭。考查了操作条件对产品性能的影响。

The activated carbon of surface area of 2918m 2/g was made in this paper through a low and a high temperature heat treatments of the mixture of KOH and coal char under Ar flow The main factors that influence the properties of the activated carbon was investigated The produced activated carbon was analysed with Xray diffraction
