CATALYST FOR PURIFICATION OF NITROGEN OXIDES

摘要

PURPOSE:To obtain the title catalyst capable of reductive decomposition of NOx without poisoning by SOx by the catalytic reaction with the addition of ammonia, and having excellent endurability, by allowing a catalytic substance containing V and P to be supported on an alumina carrier, and further allowing another catalytic substance consisting of TiO2 and V to be supported on the outer layer of the carrier.
