Research Progress of Adsorption Properties of Carbon Adsorbents for VOCs

针对不同的碳基吸附材料(活性炭、生物质碳、碳纳米管和碳硅复合材料),分别从吸附材料结构参数、有机废气分子性质、水蒸气含量及吸附温度等因素对VOCs吸附性能的影响进行综述。简单介绍了其原理、特点及应用水平,并指出碳基吸附剂结构参数和吸附过程中的操作参数对吸附量的影响,提出了碳基吸附剂在VOCs吸附工艺中的发展前景。在不断提高碳基吸附剂对VOCs吸附量的同时,提高循环再生性能,降低工业生产中高温和潮湿环境对吸附量的影响,是今后碳基吸附剂研究的方向。

The adsorption properties of carbonaceous adsorbents(such as,activated carbon,biochar,CNTs and carbon⁃silica composites)for VOCs were summarized in this paper.The influence of the structure of adsorbents,the characteristics of VOCs,the humidity and the adsorption temperature were analyzed respectively.The development prospect of carbonaceous adsorbents in the future VOCs adsorption process was proposed.While continuously increasing the adsorption capacity of carbonaceous adsorbented for VOCs,improving the performance of recycling,reducing the impact of high⁃temperature and humidity environments on the adsorption capacity in industrial production was a new trend in the research and development of carbonaceous adsorbents in the future.
