Hydrogen removal characteristics of silver zeolite AgX

Abstract

Silver zeolite AgX plays a catalyst role in the reaction of hydrogen and oxygen. When a severe accident happens, it is necessary to remove the hydrogen timely in order to prevent containment vessel from being broken. For this reason, we have investigated the suitability of AgX. As the results, AgX shows a weak catalytic activity under the conditions of steam 50%, hydrogen 3% and 75 ºC. On the other hand, when the temperature is higher than 140 ºC and residence time is as short as 0.05 second, 90% hydrogen can be removed.
