这个我必须答一个。利益相关,从事活性炭生产和销售的。题主的原话:整个吸附、解析过程中,除了丙同、活性炭,只有空气了。问题是活性炭不只是碳原子或者石墨分子,还有灰分,灰分的成分包括但不限于氧化钙,氧化镁等等成分。金属盐的存在会其某些氧化反应的催化作用。根据这个行业的经验,采用一些灰分含量高的活性炭品质吸附丙同,会出现回收的丙同等纯度低,有颜色,炭柱温度升高过快等缺点。至于解决方案自然是采用低灰分的活性炭,找对人才能解决问题。
感谢楼上大神的回复,我这生产中使用的是日本进口的活性炭,丙同的品质没有啥问题。就是丙同在进一步精制前要加碱中和下酸。
酸的产生,个人判断是活性炭中的金属盐催化氧化丙同造成的。日本进口的炭如果是煤质柱状活性炭,一样有纯度不高的问题,这个是材质属性决定,不是品牌决定。当然如你是采用的椰壳柱状炭,那就不是纯度的问题了,那就当我没说;P。
