Abstract
Official abstract text for this publication.
A method for regenerating an NO x removal catalyst, the method being capable of readily restoring the catalytic activity of a deteriorated NO x removal catalyst; being performed by simple operations; and attaining high operational efficiency. The method for regenerating an NO x removal catalyst 14 employed in a flue gas NO x removal apparatus includes immersing the NO x removal catalyst at ambient temperature in regeneration water 31 containing substantially no chlorine and no cleaning component; removing the catalyst from the regeneration water; and removing water from the catalyst.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for regenerating an NO x removal catalyst employed in a flue gas NO x removal apparatus, characterized in that the method consists of (i) a first step of immersing the NO x removal catalyst in the form of a columnar honeycomb structure, wherein the NO x removal catalyst contains at least one of Ti, V, W and oxides thereof, which NO x removal catalyst having been used to remove NO x from flue gas, with bubbling from the NO x removal cata…
