微波-催化剂法制取山核桃壳活性炭的研究

以山核桃壳为原料。采用微波-催化剂法制取活性炭。结果表明：山核桃壳中灰分、挥发成分、固定炭等成分符合活性炭对原料的要求；采用微波-催化剂法制竿的活性炭．因催化剂种类不同性能存在差异，用酸性催化剂A时，随用量的增加，活性炭亚甲基蓝脱色能力明显增强，碘值也有一定程度的增加；用中性催化剂B时，没有这种规律性。以磷酸为活化剂、微波为热源生产的活性炭性能较好，亚甲基蓝脱色力达12ml／0．1g，碘值为784mg／g；并且随着活化蒯含量的增加活性炭亚甲基蓝脱色力有明显的增加，碘值也有一定幅度的增加。此外，微波功率对亚甲基蓝脱色力的影响也较大。

Study on Technology of Production of Activated Carbon by Microwave-Catalyze

The activated carbon was made from Hickory Hull by Microwave-Catalyze. Results showed that it was adapted to activated carbon with Hickory hull. The performance of activated carbon was different due to catalyzer type; i. e. the performance of activated carbon was improved when catalyzer A was increased in some dose. The best technology was that hickory hull was infused 48 hours in 40% phosphoric acid, in which 4% sulfuric acid and 2% H_2O_2 were additive, and then radiated 10 min by microwave at 700W. The experiment showed that the methylene blue de-coloring ability reached 12mL/0.1g and iodine value reached 784 mg/g.
