Abstract

PURPOSE:The voids of a catalyst packed layer of a catalytic reaction apparatus for denitration, etc. is increased by taking out a part of the catalyst from the bottom of the layer before passing gas, in order to prevent clogging of the catalyst due to dust and control pressure loss over a long time.
