[Social Robotics] [default] The effect of activated carbon on pollution control

用于活性炭减活的常用试剂​​是长链脂族化合物,例如硬脂酸,油酸,十一烷酸,十八烷,十八烷胺等,其中最常见的是硬脂酸。然后,未吸附的材料通过第二活性炭,较少吸附的材料被吸附在第二塔上,最后未吸附的材料最终通过第一活性炭。https://www.dxdcarbon.com/

因此,通过依次通过三列,用适当的洗脱剂洗脱吸附物质,可以很好地分离非常复杂的天然药物成分。

由于活性炭粉的细小颗粒,操作不方便,因此在实际应用过程中,一般尽量不要使用第一类活性炭。

没有粉状活性炭的另一个重要原因是粉状活性炭吸附过强,吸附的物质很多,很难洗脱,通常在吸附剂失活后才会使用。

作为我国的主要能源,煤炭在开发利用过程中燃烧产生的污染物也日益恶化了大气环境。

控制燃煤产生的二氧化硫和氮氧化物污染已成为大气环境控制中最紧迫的任务。https://www.dxdcarbon.com/product/coal-granular-activated-carbon-price-per-ton

目前,我国已应用了湿法,半干法,干法脱硫,选择性催化还原脱硝,湿法联合脱硫脱硝技术,电子束法等烟气净化技术。

化学活化法是将原料和化学药品按一定比例混合,浸渍一段时间,在适当的温度下捏合和塑化,然后一步完成碳化和活化。

常用的化学品是ZNC12,H5PO和KOH。

目前,关于H的研究更多。

PO4活化方法,工艺过程如图1-2所示。

化学活化过程的特点是活化温度低(一般为400-600 ),易于调节产品的孔结构。

但是,它也有一些缺点:(1)它对设备具有很高的腐蚀性;(2)污染环境等,使化学方法受到一定程度的限制。

国内外对通过添加H3PO4进行激活的研究很多。在中国,通过与木屑磷酸方法,自20世纪80年代末原料已进行了准备活性炭的开发和研究工作它已成功地投入在20世纪90年代的工业应用中孔(转换孔)通过磷酸活化法生产的产品的结构已得到很好的开发,具有广泛的应用领域。
