[".丙同在活性炭中的反应"

Thread Content

[".使用活性炭吸附丙同(丙同回收、活性炭再生)的过程中,会有很少量的酸产生。一直很迷茫,求教酸生成的反应,谢谢。PS: 整个吸附、解析过程中,丙同、活性炭只有空气了。"

[".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,s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,一直有纯度不高的问题,这个是材质属性决定、不是品牌决定。;
