Advanced Cordierite SCR Catalyst Solutions for Industrial and Mobile DeNOx The Cordierite SCR Catalyst is a high-performance ceramic monolithic solution designed for Selective Catalytic Reduction (SCR) technology. It serves as a critical substrate for reducing harmful nitrogen oxides (NOx) from combustion exhaust, converting them into benign nitrogen (N2) and water vapor (H2O). The chemical equations for the selective catalytic reaction are as follows: 4NO + 4NH₃ + O₂ → 4N₂ +
