Abstract
A method for adsorbing and removing ethylene in an exhaust gas, comprises contacting with the gas an adsorbent comprising a zeolite which contains Ag and which has a ferrierite structure with a SiO2/Al2O3 molar ratio being at least 15.
Claims1
A method for adsorbing and removing ethylene in a gas, which comprises contacting an adsorbent consisting essentially of a zeolite which contains Ag and Pd and which has a ferrierite structure with a SiO2/Al2O3 molar ratio being from 21 to 1,000, said adsorbent adsorbing at least about 18.8×10−5 mol/g ethylene and the desorbing peak temperature for ethylene being at least about 330° C., with said gas.
