摘　　要：使用瓷窑消烟除尘后回收的粉煤灰制备活性炭.结果表明,用这种粉煤灰,只要其灰分含量小于20％,就可以制备出性能较好的粒状活性炭.活性炭的苯吸附容量达400mg/g,碘值约700mgI_2/g,四氯化碳吸附率约55％,比表面积约1000m^2/g,可用于有机溶剂回收,空气与水的净化及作催化剂载体.The authors studied the possibility of making activated carbon from coal fly ash which was recovered by removing dust in the kiln of a ceramic work-shop. The research results showed that satisfactory granular activated carbon could be made from coal fly ash so long as the ash content of the fly ash was less than 20%. The activated carbon had 4QOmg C6H6/g adsorption capacity, 700mg I2/g iodine number,55% CC14 activity, 1000m2/g specific surface area. This activated carbon can be used for organic solvent recovery, gas/water purificaton and as the carrier of catalysts.
