活性炭吸附甲烷的影响因素研究

Influence Factors of Methane Adsorption on Activated Carbon

吸附天然气(ANG)是一种常温、中低压条件下新兴的天然气存储技术,而活性炭是具有商业应用价值的吸附剂选择之一。综述了活性炭的孔隙结构(比表面积、微孔容积和堆积密度)、操作参数(吸附温度和吸附压力)、吸附热效应和其它组分对其吸附甲烷的影响规律。以期通过本文的讨论,能够对吸附天然气技术发展提供一定的基础依据。

Adsorbed natural gas(ANG)is a new gas storage technology under the conditions of normal temperature,medium and low pressure.Activated carbon is one of the adsorbents with commercial application value.In this paper,the effects of pore structure(specific surface area,micropore volume and bulk density),operating parameters(adsorption temperature and pressure),adsorption thermal effect and other components on methane adsorption of activated carbon were reviewed.This paper can provide some basic basis for the development of natural gas adsorption technology.
