<p>PURPOSE:To enhance adsorbing and storing ability to natural gas even under low pressure by an adsorbent. CONSTITUTION:A simple substance or a compd. of a metal capable of chemically adsorbing methane is deposited on activated carbon having about 750m<2>/g BET specific surface area by about 0.1-30wt.% of the amt. of the activated carbon. The metal is a group IIA metal of the periodic table such as Mg, Ca or Ba, a group VIA metal such as Cr, a group VIIA metal such as Mn, a group VIII metal such as Fe, Co or Ni, a group IB metal such as Cu, a group IIB metal such as Zn or Cd or a group IIIB metal such as Al and oxide or hydroxide thereof may be used as the compd. When the resulting adsorbent, is used, a large amt. of natural gas is efficiently adsorbed even under low pressure.</p> |
