ceramic catalytic converter

Honeycomb ceramics as a carrier are the key part of three-way catalytic converters. The honeycomb structure with thousands of parallel channels forces the exhaust gas into a turbulent state, resulting in a better exhaust effect. The contact between emissions and precious metals improves the mass transfer conditions and improves the conversion efficiency. Therefore, the cordierite ceramic honeycombs have been developed as substrates for automotive catalytic converters to solve the environmental pollution problems.
