METHOD FOR PRODUCING HONEYCOMB CATALYST, METHOD FOR PRODUCING DENITRATION CATALYST OF DENITRATION DEVICE, AND METHOD FOR PRODUCING EXHAUST GAS DENITRATION DEVICE

摘要

Provide a denitration catalyst and flue gas NO x removal apparatus of the honeycomb catalyst, a denitration apparatus that can be used efficiently, thereby reducing the running costs of the flue gas NO x removal catalyst according to the NO x removal system about half. At the entrance side at the same time having a gas flow path for passing a gas to be treated over the outlet side as a honeycomb catalyst for performing processing on the side walls of such gas passage, the degree the flow of the gas to be treated is passed into said gas flow path to be rectified in the vicinity of the outlet It should have a length of. ; The honeycomb catalyst, flue gas denitrification
