Abstract

Catalytic recombination of hydrogen and oxygen as radiolysis gases was studied using ceramic blocks of cellular structure as a catalyst support. The characteristics of the catalyst samples obtained were compared to those of the presently used granulated catalyst RK-102-12 (OPK-2). The possibility of preventing the transition of the catalytic recombination of hydrogen and oxygen to the flame combustion mode by making a catalyst with “gradient” activity was examined. The results obtained confirm good prospects for using the cellular ceramic as a catalyst support for passive hydrogen recombiners to ensure hydrogen safety at nuclear power plants.

蜂窝陶瓷作为催化气体用于放射性气体复合装置的载体

摘要

以多孔结构的陶瓷块作为催化剂载体，研究了氢和氧作为放射分解气体的催化复合。将获得的催化剂样品的特性与目前使用的粒状催化剂RK-102-12（OPK-2）的特性进行比较。研究了通过使催化剂具有“梯度”活性来防止氢和氧催化重组转变为火焰燃烧模式的可能性。获得的结果证实了使用多孔陶瓷作为被动氢重组器的催化剂载体以确保核电厂氢安全的良好前景。
