采用水蒸气物理活化法、催化炭化法和KOH活化法制备了城市固体废弃物基炭材料.利用亚甲基蓝吸附值来评价制备碳材料的吸附特性,研究了不同制备方法对碳材料得率和吸附容量的影响.其中催化炭化法制备的碳材料的得率最高;KOH活化法次之.就吸附性能而言,KOH活化法是一种更好的活化方法.在不同组分固体废弃物基碳材料中,单组分的纸板,双组分的轮胎和纸板,三组分的轮胎、纸板.PVC及多组分混合物混合制备的碳材料的吸附特性要分别优于其他单组分、双组分、三组分及多组分混合物.
Three different preparation methods including steam physical activation, catalytic carbonation and KOH chemical activation methods were used to prepare municipal solid waste- based carbon materials. The methylene blue (MB) adsorption value was applied to evaluate the adsorption capabilities of the prepared carbon materials. The effects of preparation methods on adsorption capability and yield of products were investigated. The yield of carbon materials with the catalytic carbonation method is the highest, and the KOH activation method is the second level. Considering the adsorption performance, the KOH activation method is much more favorable. Among the different components of municipal solid waste-based carbon materials, the adsorption properties of the single component of paperboard, the double components of tire and paperboard, the triple components of tire, paperboard and polyvinyl chloride (PVC), and the multi-component mixtures are better than those of other single-, double-, triple- and multi-component mixtures, respectively.
