摘要
研究分析了利用太西无烟超低灰纯煤生产的压块净水活性炭的技术指标、孔结构特征及其吸附特性;该活性炭内部以两种孔径范围的微孔为主,BET表面积高达764.83 m2/g,在P/P0为0.30时最大比表面积为809.776 m2/g,最大孔容积为0.412 cm3/g,是一种灰分低、强度高、吸附性能优良的净水活性炭。
Pressed blocks of activated carbon for water purification made of Taixi ultra-low ash anthracite;its technical index studied and analyzed: the internal micro-pores being consisted mainly of two size ranges,BET specific surface being up to 764.83 m2/g,while P/P_0=0.30,the maximum specific surface being 809.766 m2/g and maximum pore volume,0.412 cm3/g;it is a low-ash,high strength,good adsorption activated carbon for water purification.
