LiqTech DOC Diesel Oxidation Catalyst

The combination of a LiqTech's high porosity silicon carbide honeycomb structure and diesel oxidation catalyst gives unique properties:

• High conversion of CO, HC and PM(sof fraction)
• Sulfur resistant
• 'Fit and forget' solution requiring no maintenance
• High mechanical strength
• High temperature durability
• Long durability and long life expectancy
• Low pressure drop
• Low cost

LiqTech’s diesel oxidation catalyst is a cost effective way to reduce diesel exhaust emissions. It can eliminate hydrocarbons and carbon monoxide and reduce particulate matter’s SOF fraction. The catalyst does not require ultra low sulphur diesel and is resistant to ash produced by the burning of engine oil, making it suitable for a wide variety of vehicles.

The typical system performance of the the DOC is show in below chart.

The carbon monoxide and hydrocarbons react with oxygen in the presence of the
catalyst, removing them from the exhaust gas stream. This reaction is
particularly suitable for oxygen-rich (‘lean’) gas streams, typical of a diesel
exhaust.

CO ½O₂ -> CO₂
[HC] O₂ -> CO₂ H₂O

The catalyst is deposited onto the silicon carbide honeycomb and are available in following sizes:

CPSI 150 180 250
