Catalyzed Diesel Particulate Filter
flow-through Particulate Filter
Catalyst Application  
catalyzed diesel particulate filter
    With increasing appearance of diesel engine automobile, the particulate
from emission, mainly carbon, enhances the pollution to the enviroment. The US enviromental office promulgated the particulate.regulation for diesel engine, stipulating the particulate in diesel passenger car's emission should meet the criterion :below2.0g/mile. The diesel particulate filter is able to filter above 80% carbon smoke particulate .For  practicel  application, it would be a great help to solve the problem of air pollution in city. 
Major  Features:
   1) Uses porous porcelain materials and porous sintered metal as filtration
    materials, which can filtrate the solid particles in the diesel displacement,
    thus meeting the exhaust particle requirements of the displacement laws
    and regulations.
   2) According to the engine uses and operations, physical and chemical methods
    are adopted to eradicate the particles periodically, so that the displacement
    resistance can be maintained in a certain level and not influenced by the diesel
    performance
   3) The particle filtration efficiency of the diesel is more than 90%
   4) Heat regeneration is made through the displacement management, and the
    ashes left from the regeneration shall be cleaned regularly
   5) Systematic designs are available upon customers' requirements, so as to reach
    the demands of different displacement standards.

Catalyzed Diesel Particulate Filter
our particulate filters are highly effective in the elimination of particulate matter (PM10) or soot from diesel exhaust,our company offers a variety of filter coatings and designs, depending on the engine application and duty cycle.please contact our company for assistance with choosing the right filter for your application. Our verified diesel particulate filters effectively remove diesel particles and diesel fumes from diesel engine exhaust emissions. our diesel particulate filters are used to meet MSHA standards for particulate matter in underground mines, EPA or CARB mandated standards for particulate emissions in diesel vehicle retrofits, or simply to improve the air quality in a work site containing diesel engines.

three-way catalyst
     The three-way catalyst is used in rich-burn or stoichiometric engines for simultaneous conversion of oxides of nitrogen (NOx), carbon monoxide (CO), hydrocarbons (HC), formaldehyde (CH2O) and EPA classified Hazardous Air Pollutants (HAPs). The three-way catalyst is effective in a wide variety of engine applications and fuels, including natural gas, propane and gasoline. A closed loop air-fuel ratio controller is required for the three-way catalyst to work effectively.
Oxidation catalyst
    The oxidation catalyst is effective for the control of carbon monoxide (CO), non-methane hydrocarbons (NMHC), volatile organic compounds (VOC), formaldehyde (CH2O) and EPA classified Hazardous Air Pollutants (HAPs) from natural gas and LPG lean-burn engines. The oxidation catalyst is also effective for catalytic combustion of VOC emissions from a variety of exhaust gas streams from industrial processes.
Diesel oxidation catalyst
     The diesel oxidation catalyst (DOC) is effective for the control of carbon monoxide (CO), hydrocarbons (HC), odor causing compounds and the soluble organic fraction (SOF) of particulate matter (PM10)
