HYDROCARBON ADSORBENT AND METHOD FOR ADSORBING/REMOVING HYDROCARBON BY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a hydrocarbon adsorbent and a method for adsorbing/removing a hydrocarbon by using the hydrocarbon adsorbent.SOLUTION: The hydrocarbon adsorbent, which comprises such clinoptilolite type zeolite and/or ferrierite type zeolite that the barium content (barium ion exchange rate) thereof accounts for 5 mol% or more of the total moles of cations, is obtained by bringing the clinoptilolite type zeolite and/or ferrierite type zeolite into contact with a barium-containing aqueous solution to exchange ions therebetween.
