Zusammenfassung:The invention belongs to the technical fields of environmental materials, environmental catalysis and environment protection, and particularly relates to a honeycomb denitration catalyst for flue gas at 400 DEG C-600 DEG C and a preparation method of the honeycomb denitration catalyst. The honeycomb denitration catalyst comprises a catalyst coating and honeycomb ceramics, wherein the sizing agent of the catalyst coating is prepared from the following components in percentage by weight: 15-25% of zeolite, 5-10% of gamma-type aluminium oxide, 5-10% of a catalytic promoter, 5% of a binder and 50-70% of deionized water. The honeycomb denitration catalyst contains the catalytic promoter, and has excellent high-temperature denitration activity, excellent sulphur resistance and excellent water tolerance, excellent stability and excellent NOx removing capability.
