GAS STORAGE USING FULLERENE BASED ADSORBENTS

摘要

Gas absorbents with high gravimetric and volumetric gas adsorption capacitie s are made from fullerene-based materials by pressing fullerene powder into pellet form and polymerizing the fullerene by subjecting it to high temperature and high inert gas pressure. The gas adsorption capacities of th e fullerene-based adsorbents can be further enhanced by pre-chemical modification or post-polymerization activation processes. The adsorbents can be used to store oxygen, hydrogen, nitrogen, carbon dioxide and water vapor by employing a body of fullerene-based adsorbent material (102) contained withi n a closed vessel (101) suitable for maintaining the stored gas at the require d pressure and provided with a valved inlet and outlet (103A) for introducing and withdrawing the gas to be stored therein through tube (103).
