氯化锌活化制备枣核活性炭研究

Study on preparation of activated carbon from Jujube-stone with zinc chloride

探索枣核粉木质活性炭制取的新方法,深入研究大枣核的利用价值。以50%氯化锌为活化剂,用煅法制备活性炭。在煅制时间为25 min时,制备活性炭性能最佳,产率为45.4%,碘吸附值为891.69 mg/g,亚甲基蓝脱色力为278.65 m L/g。煅法制备活性炭工艺简单易行,成品性质稳定。

; To explore a new method of wooden activated carbon prepared by Jujube-stone powder and study the value of Jujube-stone in-depth. 5 0 % zinc chloride as activating agent, preparation of activated carbon by calcining method. Results showed that the optimum condition was in the calcining time 25 min prepared activated carbon has the best performance, under the above optimum conditions, the yield, iodine value and methylene blue value were 45. 4 % ,891.69 mg/g and 278.65 mL/g , respectively. The preparation of activated carbon calcining process was simple and the product properties was stability.
