天然气汽车甲烷专用吸附剂的研究开发概况

Survey of study and development of methane special adsorbents for natural gas vehicles

综述了国内外天然气汽车专用吸附剂的研究开发情况和发展动态 ,指出中低压天然气吸附储存技术 (ANG)是一种可替代目前普遍应用的高压储存技术 (CNG)的新型的天然气储存技术 ,该技术的关键是研制专用的天然气吸附剂 ,国内外在这方面作了大量的工作并取得可喜的成果 ,国内以木质素为原料制备的吸附剂在 3 5MPa时所储存的天然气可以达到并超过 2 0MPa时CNG所储存的天然气气量。

The status of study and development of methane special adsorbents for natural gas vehicles at home and abroad is described.It is indicated that the technology of adsorbed natural gas(ANG) at mild pressures will be an alternative of the one of compressed natural gas(CNG),which has been used widely at present.The key of this technology is the development of natural gas special adsorbents.Many works have been made in this field,and some excited results have been obtained.The adsorbents prepared at home from lignose can adsorb the equal or more amount of natural gas at 3.5MPa than that one of CNG at 20MPa.
