摘要： A method for regenerating an NOx removal catalyst, the method being capable of readily restoring the catalytic activity of a deteriorated NOx removal catalyst; being performed by simple operations; and attaining high operational efficiency. The method for regenerating an NOx removal catalyst 14 employed in a flue gas NOx removal apparatus includes immersing the NOx 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.

摘要： The present invention provides a honeycomb catalyst and an NOx removal catalyst for use in an NOx removal apparatus which can be employed at high efficiency, and a flue gas NOx removal apparatus, whereby the running cost of a flue gas NOx removal system in terms of the NOx removal catalyst is reduced by about one-half. The honeycomb catalyst having gas conduits for feeding a gas to be treated from an inlet to an outlet of each conduit and performing gas treatment on the sidewalls of the conduit, wherein the honeycomb catalyst has an approximate length such that the flow of the gas to be treated which has been fed into the gas conduits is straightened in the vicinity of the outlet.
