【摘要】 天然气可用液化、压缩和吸附三种方式来存储。对于车用而言,液化方法实用性有限而压缩天然气需要高压及昂贵的多级压缩设施。吸附式存储被认为是车用天然气存储中最有希望的方法。但应用中的一些实际困难限制了这项技术的实用化。ANG的希望取决于吸附热问题的有效解决及价廉且具有高的比体积甲烷存储容量的吸附剂的开发。同时,对于超临界甲烷在多孔吸附剂上的吸附机理,需展开深入的研究。更多还原

【Abstract】 Natural gas may be stored by liquefaction, compression, or adsorption.For use as a transportation fuel, liquefaction is limited by practical difficulties and compression requires high pressure and an expensive multi-stage compression facility. Adsorption storage is the most promising low-pressure alternative for storing natural gas as a vehicle fuel, but some operational difficulties hinder the success of this technology. The hope for ANG vehicles depends on further development in the areas of heat management and adsorbents, which have high volumetric methane adsorption capacities. Meanwhile, further study is needed to understand the mechanism of supercritical adsorption of methane on microporous adsorbents.更多还原
