活化椰殼活性炭的時需要采取的方式有哪些呢

活化(hua)椰殼(ke)活性(xing)炭的時分(fen)，改動(dong)蒸汽的流量，會使得、椰殼(ke)活性(xing)炭的比外(wai)(wai)表積、外(wai)(wai)比外(wai)(wai)表積、總孔(kong)容(rong)(rong)和(he)中孔(kong)孔(kong)容(rong)(rong)均呈現變化(hua)。

整體上來說，不時增(zeng)加水氣流量，椰殼活性(xing)炭微(wei)孔比外表積和微(wei)孔孔容先增(zeng)大(da)后(hou)減小。

水氣(qi)含(han)量較小時(shi)，椰殼(ke)活性炭的比外表積(ji)(ji)相對(dui)較低(di)，但是由于(yu)沒有足夠多(duo)的水氣(qi)分子(zi)和無定型碳原子(zi)發作(zuo)反響，所以(yi)不能開辟更(geng)多(duo)的新孔。因而微孔所占的比例較大，微孔比外表積(ji)(ji)也比擬高。

當水(shui)氣(qi)流量增加的(de)(de)時(shi)分(fen)，水(shui)氣(qi)分(fen)子充沛(pei)進(jin)入(ru)到物料的(de)(de)內部與碳原子發作猛烈反響(xiang)，有(you)利于新孔的(de)(de)構成，這(zhe)個時(shi)分(fen)椰殼活性炭比外表積和微孔容積都變大。

但(dan)是(shi)過(guo)高的(de)水氣，會使活(huo)(huo)性炭(tan)呈現過(guo)燒現象，水蒸氣與(yu)炭(tan)的(de)充(chong)沛反響把(ba)鏈(lian)接微孔(kong)(kong)(kong)(kong)(kong)間的(de)炭(tan)壁燒蝕掉，從而使微孔(kong)(kong)(kong)(kong)(kong)所占(zhan)比例降低(di)。這(zhe)個時分微孔(kong)(kong)(kong)(kong)(kong)比外表(biao)積變小(xiao)，中(zhong)(zhong)孔(kong)(kong)(kong)(kong)(kong)比外表(biao)積變大(da)，活(huo)(huo)性炭(tan)總(zong)孔(kong)(kong)(kong)(kong)(kong)容(rong)(rong)變大(da)，微孔(kong)(kong)(kong)(kong)(kong)孔(kong)(kong)(kong)(kong)(kong)容(rong)(rong)變小(xiao)，中(zhong)(zhong)孔(kong)(kong)(kong)(kong)(kong)孔(kong)(kong)(kong)(kong)(kong)容(rong)(rong)變大(da)。
