EXPERIMENTAL

Adsorbed natural gas storage is being considered as an on-board storage technology for natural gas vehicles because it costs less to build and to refuel than does compressed natural gas storage. ~Carbon-based adsorbents have been found to have the most favorable gas storage density compared to other adsorbents. 2,3 The objective of this study is to develop a technology for producing adsorbent carbons from Illinois coal and scrap tire and evaluate the potential application of these materials for use in low pressure natural gas vehicles
