【摘要】 从炭化物的灰分对煤基活性炭吸附性能的影响出发，对摩擦电选生产的超低灰煤（灰分低于2％）制备活性炭进行了研究，制备出友分为3.9％，比表面达1312m2／g,碘值达1165mg／g，强度达96％的优质活性炭。更多还原

【Abstract】 According to the effects of the ash of carbide on the adsorption capacity of coal - based activated carbon, synthesis of activated carbon from the ultro-low-ash coal(ash is less 2%) produced by triboelectric sepowator is studied. High quality activated carbon with ash of 3.9%, specific area of 1312m/g, iodine number of 1165 mg/g and strength of 96% is prepared.更多还原
