摘要
以多种陕北机制兰炭为原料,采用KOH活化法,在氮气氛的管式炉中进行高温活化,制备出了BET比表面为810.017 2m2/g,BJH平均孔径为6.579 3nm的活性炭.考察了活化温度、时间、碱炭比、碱炭混合方式和兰炭种类等对活性炭吸附性能的影响,确定活性炭的最佳制备工艺为:以兴茂兰炭为原料,KOH干粉法活化,活化条件为800℃下1h,碱炭比为5∶1.
With Shanbei machine-made semicoke as the raw material, the actived carbon was prepared in the N2-atmosphere tube furnace by KOH activation method, whose BET specific surface area is 810. 017 2 m2/g and BJH mean pore size is 6. 579 3 nm. The activation temperature and time, alkali/semicoke ratio, mixed styles of alkali and semicoke, and semicoke types were considered to have effects on the adsorption performance of active carbon. The optimum preparation procedure is determined that Xingmao semicoke is used as the raw material, KOH powder is used as the activated agent, the activation temperature is 800 ℃, the activation time is 1 h and the ratio of alkali/semicoke is 5 ： 1.
