摘　　要：宝钢沥青焦具有灰分低、碳含量较高的特点,以宝钢沥青焦为原料,采用KOH活化法制备超级活性炭,并对其吸附性能进行测定。结果表明,该活性炭吸附性能优异,当活性炭碱碳比为4∶1和5∶1,活化温度为800℃时,碘、亚甲蓝、苯吸附值分别达到2 340mg/g～2 480mg/g、445mg/g～455mg/g、1 430mg/g～1 440mg/g,BET比表面积可达2 890m2/g～3 150m2/g,主要性能指标达到日本Marxsorb活性炭水平。试验表明,在制备超级活性炭的过程中,碱碳比是重要的影响因素,其次是温度。The pitch coke(green coke) from Baosteel contains low content of ash and comparatively high content of carbon.Super-activated carbon was prepared from the Baosteel pitch coke by KOH activation,which exhibits excellent adsorption performances.The adsorption capacities of iodine,methylene blue and benzene reach 2 340-2 480 mg/g,445-455 mg/g and 1 430-1 440 mg/g respectively.The BET specific surface area of the activated carbon is as high as approximately 2 890-3 150 m2/g.The main properties of the products re...
