KOH-水蒸气活化法制煤基活性炭和氢气的研究
STUDY ON A NEW METHOD FOR PREPARATION OF COAL-BASED ACTIVATED CARBON CONBINED WITH HYDROGEN
摘要
Abstract
Activated carbons and hydrogen were prepared by KOH activation combined with steam activation from Shenfu 3＃ coal. Effects of ratio of KOH to the coal, heat treatment temperature, activation time on activated carbons performance and hydrogen product were studied. Activation mechanism was also discussed. The results indicated that iodine number is 837 mg/g,methylene blue adsorption value is 430 mg/g with the activated carbon prepared at 700 ℃ for unit activation time 10 min, with addition of KOH whose ratio to the coal is 0.5. Under the same condition, about 33.1 mmol for each gram of coal is released during the activation.关键词
