WGSR/DENOX COMBINED CATALYST APPLIED TO PASSIVE DENOX IN DIESEL OR LEAN-BURN EXHAUST GAS

摘要

A DeNOx complex catalyst for removing diesel or lean burn engine exhaust gas nitrogen oxide is provided to remove efficiently NOx because the catalytic reduction of the NOx included among the exhaust gas composition is accelerated. A DeNOx complex catalyst for removing diesel or lean burn engine exhaust gas nitrogen oxide is as follows. The DeNOx complex catalyst the aqueous gas transfer reaction(WGSR) catalyst is mixed. The DeNOx catalyst is the Pd / TiO2 / Al2O3. The WGSR catalyst is the mixture of the metal oxide and metal.
