Catalytic Reduction Of Nitric Oxide By Solid Carbonaceous Material Under Lean Condition, Shan Xiao

Dissertations

The reactions of O₂, NO_x and soot from Diesel exhaust over Cu containing catalysts can significantly reduce soot and NO_x emissions while producing N₂ and CO₂. The author has evaluated the performance of Cu ion exchanged ZSM-5 and Cu adsorbed on Granulated Activated Carbon (Cu-GAC) using GAC as a surrogate for soot in a packed bed reactor. CO, formed primarily by the oxidation of GAC with O₂, appears to be a stable intermediate in the reduction of NO. With experimental parameters chosen to simulate Diesel exhaust conditions, Cu-GAC is much more …
