Abstract
The present invention relates to a continuous type catalyst regeneration process for continuously heating and regenerating a degraded catalyst from a denitration apparatus and recycling the regenerated catalyst to the denitration apparatus for repeated use thereof. In accordance with the present invention, a degraded catalyst is intermittently and by predetermined amounts charged into a heating furnace through a first damper mechanism in a gas-sealed state while the surface level of a catalyst held in the heating furnace is maintained lower than the outlet of catalyst regenerating gas and is therein subjected to heat-treatment at a temperature of 400.degree.-650.degree. C. with catalyst-regenerating gas introduced into the heating furnace. Thus regenerated catalyst is intermittently and by predetermined amounts discharged from the heating furnace toward a second damper mechanism through a catalyst delivery mechanism and recycled to the denitration apparatus.
