Denitration catalyst and method.

摘要

A catalyst for denitration of exhaust gas containing NOx which comprises a Cu (II) exchanged Y zeolite which is produced by exchanging 60 to 200% of exchangeable Na ions in a Na-Y zeolite with Cu(II) ions. Also, a method of using the catalyst. It becomes possible to carry out denitration at higher efficiency than a conventional vanadium-titania catalyst. <IMAGE>
