ADSORBENT FOR HYDROCARBON AND REMOVAL METHOD BY ADSORBING HYDROCARBON

摘要

PROBLEM TO BE SOLVED: To provide a high heat-resistant adsorbing agent having an excellent adsorption capacity and an excellent adsorption retaining force of hydrocarbon in co-presence of water and not influencing adsorption performances of the hydrocarbon by an atmosphere of a treating gas and a method for adsorbing and removing the hydrocarbon contained in the treating gas using the adsorbent. SOLUTION: Zeolite in which an absolute value of charge of oxygen determined from an electronegativity averaging principle of Sanderson is 0.210 or higher and a molar ratio of SiO2 /Al2 O3 is 30 or higher is used as the adsorbent for hydrocarbon.
