<p><P>PROBLEM TO BE SOLVED: To provide a hydrocarbon adsorbent having a large amount of hydrocarbon to be adsorbed, its large holding power and a sufficient heat resisce, and to provide an adsorbing method of hydrocarbons adsorbing and removing hydrocarbon contained in a gas by the adsorbent. <P>SOLUTION: In the hydrocarbon adsorbent, when a hydrocarbon selected from groups of a 7 or more C straight chain paraffin, a 7 or more C straight chain olefin and a polycyclic aromatic compound is adsorbed at a room temperature, and then desorbed by raising its temperature, the amount of the hydrocarbon desorbed at 200°C or higher is 40 mass% or more of the total amount of the desorbed hydrocarbon. Further, in the adsorbing method of hydrocarbons, the 7 or more C straight chain paraffin, the 7 or more C straight chain olefin and/or a polycyclic aromatic hydrocarbon compound in a gas are adsorbed by making the gas into contact with the adsorbent. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
