Visual Observation of de-NOx reactor with Honeycomb Catalysts

Abstract

ABSTRACT; The honeycomb catalysts were used for the de-NOx of diesel engine. The flow uniformity of exhausted gas in the de-NOx reactor effectuates the high de-NOx efficiency and the long life time of honeycomb catalysts. Therefore, it is important to make clear the flow distribution of exhausted gas from the diesel engine. In this report, the flow of inside the de-NOx reactor was studied experimentally by using the smoke method and the smoke wire method for visualization.A baffle was equipped in our deNOx reactor to regulate the flow distribution in honeycombs. As a result , it was made clear that the vortex produced after the baffle had an important roll for flow distribution and mixing.
