摘要
探讨了以硝酸盐为主的氧化性复合催化剂制备煤基活性炭的新工艺，利用该催化剂将催化和氧化统一起来。实验考察了催化剂对活性炭的吸附性能和活化速度的影响。结果表明，硝酸钡的活性差，不宜作为催化剂使用；钾化合物是制造活性炭的良好催化剂；助催化剂Ｐ在活性炭孔隙结构发展上起着重要的作用；原料中的灰分对催化剂效能的发挥起阻碍作用；实验的复合催化剂可以提高活化反应速度１倍以上，在相同烧失率时获得较高的吸附性能，或在相同的烧失率时提高活化得率，从而降低活性炭的生产成本。
A new way for preporration of activated carbon from coal is investigated by using nitrates as oxidative catalysts with which oxidation and catalyzing are united The effects of the catalysts on the adsorbability and activation rate are studied Barium nitrate is low in activity and not suitable for catalyst Potassium compounds are excellent catalysts for preparation of activated carbon Enhancing agent P plays an important role in the development of porous structure The ash in the feed coal lowers the catalytic ability The catalysts studied are able to double the activation rate A higher adsorbability can be obtained in the same burnoff or more product can be got in the same adsorbability, leading to a reducing cost
