Claims11
A method of removing iodine and iodine compounds from a gaseous stream, which comprises passing the gaseous stream containing iodine and iodine compounds through a layer of an adsorbent comprising a silver loaded pentasil zeolite having a silica/alumina ratio in the range of 15 to 100, whereby the iodine and iodine compounds are adsorbed in the zeolite.
A method of removing iodine and iodine compounds from a gaseous stream under conditions of high humidity which comprises passing a gaseous stream containing iodine and iodine compounds through a layer of silver loaded pentasil zeolite whereby the iodine and iodine compounds are adsorbed in the zeolite wherein said zeolite contains 5 to 15% weight percent of silver based on the weight of the adsorbent and said zeolite has a SiO.sub.2 /Al.sub.2 O.sub.3 molar ratio of from 15 to 100 and said zeolite has a particle size of 0.05 mm to 10 mm.
