Ceramic honeycomb materials are typically used as the catalyst carrier for purifying automotive/ vehicle emission( exhaust catalytic converter), removing bad smell ( for instance, air-fresher machine for hotel, restaurant, toilet and so on), Industry's organic waste gas purification. Abatement of Volatile organic compounds (VOC), hazardous air pollutants (HAP), carbon monoxide (CO), nitrogen oxides (Nox), organic particulate matter (OPM), HC nytron, SO2, odors, and other air toxics in oil and chemical industry, dust burning stove/ incinerator, power plant and so on. Also widely used in the application of Vehicle Catalytic oxidizers (CO), Regenerative catalytic oxidizers (RCO), ReNOx processes, Fixed bed adsorbers, Bio-systems. Catalytic converter catalyst supports, Its operation needs the coating of the catalyst, working as the substrate/support of catalyst.
