活(huo)(huo)性(xing)(xing)(xing)炭(tan)(tan)(tan)是一(yi)(yi)種(zhong)經(jing)特(te)殊處理的(de)(de)(de)炭(tan)(tan)(tan),將有機原料(果殼、煤、木材(cai)等)在隔絕空氣的(de)(de)(de)條件下加熱,以(yi)減少(shao)非碳成(cheng)分(fen)(此過程(cheng)稱為炭(tan)(tan)(tan)化(hua)),然(ran)后與氣體反應(ying),表(biao)面(mian)(mian)被侵蝕(shi),產生微孔(kong)發達(da)的(de)(de)(de)結構 (此過程(cheng)稱為活(huo)(huo)化(hua))。由于(yu)活(huo)(huo)化(hua)的(de)(de)(de)過程(cheng)是一(yi)(yi)個微觀過程(cheng),即大(da)量的(de)(de)(de)分(fen)子碳化(hua)物表(biao)面(mian)(mian)侵蝕(shi)是點(dian)狀侵蝕(shi) ,所以(yi)造成(cheng)了活(huo)(huo)性(xing)(xing)(xing)炭(tan)(tan)(tan)表(biao)面(mian)(mian)具有無數細小孔(kong)隙(xi)。活(huo)(huo)性(xing)(xing)(xing)炭(tan)(tan)(tan)表(biao)面(mian)(mian)的(de)(de)(de)微孔(kong)直(zhi)徑大(da)多在2~50nm之間(jian),即使是少(shao)量的(de)(de)(de)活(huo)(huo)性(xing)(xing)(xing)炭(tan)(tan)(tan),也(ye)有巨大(da)的(de)(de)(de)表(biao)面(mian)(mian)積(ji),每克活(huo)(huo)性(xing)(xing)(xing)炭(tan)(tan)(tan)的(de)(de)(de)表(biao)面(mian)(mian)積(ji)為500~1500m2,活(huo)(huo)性(xing)(xing)(xing)炭(tan)(tan)(tan)的(de)(de)(de)一(yi)(yi)切(qie)應(ying)用,幾(ji)乎都基于(yu)活(huo)(huo)性(xing)(xing)(xing)炭(tan)(tan)(tan)的(de)(de)(de)這一(yi)(yi)特(te)點(dian)。
活性炭是由石(shi)(shi)墨(mo)微(wei)(wei)(wei)晶(jing)(jing)、單一平面網狀碳(tan)和無定形碳(tan)三部(bu)(bu)分(fen)(fen)組成,其(qi)中(zhong)石(shi)(shi)墨(mo)微(wei)(wei)(wei)晶(jing)(jing)是構(gou)(gou)(gou)(gou)成活性炭的(de)主體部(bu)(bu)分(fen)(fen)。活性炭的(de)微(wei)(wei)(wei)晶(jing)(jing)結(jie)構(gou)(gou)(gou)(gou)不同于(yu)(yu)石(shi)(shi)墨(mo)的(de)微(wei)(wei)(wei)晶(jing)(jing)結(jie)構(gou)(gou)(gou)(gou),其(qi)微(wei)(wei)(wei)晶(jing)(jing)結(jie)構(gou)(gou)(gou)(gou)的(de)層間(jian)距在(zai)(zai)0.34~0.35nm之間(jian),間(jian)隙大。即使(shi)溫(wen)度(du)高達(da)2000 ℃以(yi)上也難以(yi)轉(zhuan)化為(wei)石(shi)(shi)墨(mo),這種(zhong)微(wei)(wei)(wei)晶(jing)(jing)結(jie)構(gou)(gou)(gou)(gou)稱(cheng)為(wei)非(fei)石(shi)(shi)墨(mo)微(wei)(wei)(wei)晶(jing)(jing),絕大部(bu)(bu)分(fen)(fen)活性炭屬于(yu)(yu)非(fei)石(shi)(shi)墨(mo)結(jie)構(gou)(gou)(gou)(gou)。石(shi)(shi)墨(mo)型結(jie)構(gou)(gou)(gou)(gou)的(de)微(wei)(wei)(wei)晶(jing)(jing)排(pai)列(lie)較有(you)(you)規則,可(ke)經處理后轉(zhuan)化為(wei)石(shi)(shi)墨(mo)。非(fei)石(shi)(shi)墨(mo)狀微(wei)(wei)(wei)晶(jing)(jing)結(jie)構(gou)(gou)(gou)(gou)使(shi)活性炭具有(you)(you)發達(da)的(de)孔(kong)(kong)(kong)隙結(jie)構(gou)(gou)(gou)(gou),其(qi)孔(kong)(kong)(kong)隙結(jie)構(gou)(gou)(gou)(gou)可(ke)由孔(kong)(kong)(kong)徑(jing)分(fen)(fen)布(bu)表征。活性炭的(de)孔(kong)(kong)(kong)徑(jing)分(fen)(fen)布(bu)范圍(wei)很寬,從小于(yu)(yu)1nm到數千nm。有(you)(you)學者提出將活性炭的(de)孔(kong)(kong)(kong)徑(jing)分(fen)(fen)為(wei)三類:孔(kong)(kong)(kong)徑(jing)小于(yu)(yu)2nm為(wei)微(wei)(wei)(wei)孔(kong)(kong)(kong),孔(kong)(kong)(kong)徑(jing)在(zai)(zai)2~50nm為(wei)中(zhong)孔(kong)(kong)(kong),孔(kong)(kong)(kong)徑(jing)大于(yu)(yu)50nm為(wei)大孔(kong)(kong)(kong)。
