Development of Ag/Al_2O_3 catalyst for the reduction of NO_x in exhaust gases from lean-burn natural-gas-fueled engines

摘要

Nitrogen oxides (NO_x) contained in the exhaust gases from lean-burn natural-gas-fueled engines was removed by using an alumina supported silver (Ag/Al_2O_3) catalyst without addition of reducing agent.The NO_x was efficiently reduced by unburned bydrocarbons contained in the exhaust gases over the 2 wt
