Product Description
Product Overview
Advanced DOC catalyst systems designed for diesel engine marine applications, compliant with Euro III, IV, V, and VI emission standards. These catalysts feature optimized precious metal formulations for superior low-temperature performance and efficient exhaust treatment.
Technical Performance
With increased noble metal loading and optimized Pt/Pd ratios, our DOC catalysts achieve lower T50 temperatures for CO and total hydrocarbons (THC), significantly improving conversion rates at low temperatures (300°C). The formulations are engineered to maintain high conversion efficiency across varying temperature ranges while promoting effective NO oxidation.
