Description

Cordierite SCR Honeycomb Ceramic Catalyst Carrier

Cordierite SCR Honeycomb Ceramic Catalyst Carrier

Selective catalytic reduction (SCR) is an advanced active emissions control technology system that injects a liquid-reductant agent (urea) through a special catalyst into the exhaust stream of a diesel engine. SCR catalyst can removes nitrogen oxides from diesel vehicles, in the SCR process, the reducing agent reacts with NOX to convert the pollutants into nitrogen, water and tiny amounts of carbon dioxide, which is then expelled through the vehicle tailpipe. Applications include medium and heavy-duty diesel trucks, all on round and non-road vehicle and various construction machinery vehicles.

Catalytic Converter (colloquially, “cat” or “catcon”)

A device used to reduce the toxicity of emissions from an internal combustion engine.

Working Principle of Three-way Catalytic converter:

Reduction of nitrogen oxides to nitrogen and oxygen:

2NOx → xO2 + N2

Oxidation of carbon monoxide to carbon dioxide:

2CO + O2 → 2CO2

Oxidation of un-burnt hydrocarbons (HC) to carbon dioxide and water:

CxH2x+2 + [(3x+1)/2] O2 → xCO2 + (x+1) H2O
