(1)磷酸活化法
磷酸法制备活性炭的过程中,磷酸与木质纤维原料的作用机理可分为以下几个方面:润胀作用、加速活化作用、脱水作用、氧化作用和芳香缩合作用。 [2]
磷酸活化法的基本工艺包括木屑筛选、干燥、磷酸溶液配制、混合(或浸渍) 、炭化、活化、回收、漂洗(包括酸处理和水洗)、离心脱水、干燥与磨粉等工序,如生产颗粒活性炭还需增加捏合工艺。另外,附设专门的废气净化系统,回收烟气中的磷酸和炭粉,减少对环境的污染。磷酸活化法的生产工艺中,要注意在炭化段控制度,让磷酸充分渗透入木屑,再与活化段协同控制,可以明显提高活性炭吸附能力,产品质量稳定,同时适当降低活化温度对降低产品灰分有利。炭活化尾气采用多段液相回收可以增加磷酸和细炭粉的回收,采用高压静电方式也有利于尾气中焦油的去除。
二是要看蜂窝活性炭产品所产生的气泡,如果产生的气泡越多则产品的质量就越好。我们可以做一个小实验,将一小把蜂窝活性炭产品投入水中,由于水渗透的作用,水会随之浸入活性炭的孔隙中,以此来让孔隙中的空气排出,从而产生一连串的极为小的气泡,在水中拉出一条细小的气泡线,同时又发出了兹兹的气泡声,看着十分有趣。如果这种现象发生的很剧烈的话,而且持续的时间越长,那么就证明蜂窝活性炭产品的孔隙结构非常发达,就是蜂窝活性炭的吸附性越好的表现。
The two is to look at the honeycomb activated carbon products produced by the bubble, if the bubble is more the better the quality of the product. We can do a little experiment, a handful of honeycomb activated carbon products into the water, because the water penetration effect, water will be immersed in the pores of activated carbon, so the pore in the air, resulting in a series of very small bubbles, pulled out a tiny bubbles lines in the water, at the same time also issued Zizi bubble sound, looked very interesting. If this phenomenon is very serious, and the longer the duration, then it is proved that the honeycomb activated carbon product pore structure is very developed, that is, the better adsorption performance of honeycomb activated carbon.

再生原理
活性炭再生,是指用物理或化学方法在不破坏其原有结构的前提下,去除吸附于活性炭孔的吸附质,恢复其吸附性能的过程。活性炭吸附过程中,对吸附质和溶剂都有吸附作用,因亲和力的不同,经过一定时间的吸附,达到吸附平衡。活性炭再生就是要采取办法破坏这种平衡关系,其依据主要为以下几个方面:①改变吸附质的化学性质;②用对吸附质亲和力强的溶剂萃取;③用对活性炭亲和力比吸附质大的物质把吸附质置换出来,然后再使置换物质脱附,活性炭得到再生;④用外部加热、升高温度的办法改变平衡条件;⑤用降低溶剂中溶质浓度(或压力)的方法再生;⑥使吸附物(有机物)分解或氧化而除去。
