ABSTRACT:
Natural gas is stored in a closed vessel under a pressure of about 1400 to 4500 kPa using a carbon molecular sieve adsorbent. The deliverable volume of natural gas from a vessel packed with carbon molecular sieve particles is increased by impregnating a polymer precursor of the carbon molecular sieve with additional monomers and polymerizing the monomers before carbonizing the precursor.
