摘要
为提高吸附天然气存储效率,针对吸附天然气技术中存在的问题,从活性炭吸附剂的结构设计和吸附理论研究的发展现状两个方面综述了天然气吸附及其理论的研究进展。活性炭结构设计主要是从孔结构控制和吸附热效应两个方面展开讨论。同时介绍了天然气吸附理论的研究情况,包括临界条件气体吸附的各种模型和超临界吸附。临界吸附的Langmuir,BET以及Dubbin模型都是理想的模型理论,存在着一定的局限性;超临界吸附由于体系复杂,多为实验数据的回归,缺乏明确的解释。通过上述分析,客观地指出了目前吸附天然气研究中的一些问题以及进一步发展的方向。
In order to improve the efficiency of natural gas storage,the progresses in natural gas adsorption storage were extensively reviewed with the emphasis on the structure design of relevant activated carbon adsorbents and the adsorption mechanisms.About the structure design of activated carbon adsorbents,the porous structure and thermal behavior were mainly discussed.About the adsorption mechanisms,critical adsorption and supercritical adsorption were summarized.Models like Lanmuir,BET and Dubbin all had their limitations for critical adsorption.While,for supercritical adsorption,the regression of experimental data was mostly used,that couldn't provide convincing explanation due to the complex of system.Through the analysis,the existing problems and future development directions related to natural gas adsorption storage were also pointed out.
