摘要：以玉米芯酸水解制备糠醛的废弃物为原料,采用物理法和化学法相结合的方式制造活性炭,并做了不同的工艺条件下的对比实验。实验结果表明:在由糠醛废渣制得的炭质原料中加入2%的灰分促融剂,在900℃下进行水蒸气活化,活化料用15%的盐酸进行酸洗,极大的降低了物料中灰分的含量,可制得品质较好的活性炭。活性炭的亚甲基蓝吸附值可达到180 mg/g,灰分可控制在6%,铁盐质量分数为0.08%。
Using the waste of furfural manufacture by corncob acid hydrolysis as raw material,activated carbon was prepared by the combination of physical activation and chemical activation,and the comparison experiments for different process conditions were made.The experimental results show that activated carbon with preferable quality can be produced by adding 2 % ash-fluxing agent into the raw material,subsequently activated by steam at 900 ℃,then washed by 15 % HCl,thus ash content was decreased greatly.Methylene blue adsorption value of the product can reach 180 mg/g with ash content 6 % and iron mass fraction 0.08 %.
