中文摘要：

为了解决废弃轮胎造成的资源浪费和环境污染的问题,对以废弃轮胎橡胶为碳的前驱体原料,制备具有高吸附性能中孔炭材料工艺进行了系统的研究。通过XRD、扫描电镜以及比表面积分析,对制备的中孔炭微观结构和性能进行表征,讨论了炭化温度、碱炭比,以及活化温度和活化时间等工艺条件对制备中孔炭的产率、结构和性能的影响。结果表明,通过改变工艺条件制备的中孔炭的孔径分布可以在2~80 nm范围内进行调控。在500℃炭化温度,碱炭比为4∶1,900℃活化1 h的工艺条件下,制备的中孔炭的比表面积为473 m2/g,对甲基橙的最大吸附量达到254 mg/g。

英文摘要：

The mesoporous carbon with a high absorbability was prepared from the carbonization of scrap tyre followed by chemical activation by KOH.The samples were characterized by XRD,SEM and BET method skills,and the influence of the process parameters such as the carbonization temperature,the KOH/precursor ratio,activation temperature and time on the final product were investigated.Experimental results show that the diameters of the mesoporous carbon can be controlled within a range of 2 to 80 nm.The mesoporous carbon prepared under a carboni-zation at 500 ℃,with a KOH/precursor ratio of 4∶1 to be activated at 900 ℃ for 1 h has a BET surface area of 473 m2/g and a maximal adsorption amount of 254 mg/g to the methyl orange.
