 Ceramic Honeycomb Substrate

          AceChemPack assists customers in developing specific/customized ceramic honeycomb with the competitive price and quality. We construct the required tooling, then manufacture products according to need. Customer satisfaction is our goal. Ceramic honeycomb structures offer maximum surface areas with minimal volume. Therefore, they present an ideal geometric structure for interchangeability technical processing.

          Ceramic honeycomb materials exist mainly as the catalyst support /carrier , heat exchange media, Ceramic filter plate for cast/ foundry and High alumina honeycomb ceramic plate/slice filters for sulfur removal/recovery . This series of products have already been exported to U.S.A., Germany, Korea, Japan etc.

          Cell structure density ranges from 10 to300cpsi/400cpsi/600cpsi/800 CPSI (cells per square inch). Material are typically available in cordierite, mullite and alumina etc on customer request. Honeycomb ceramics block shape: rectangular, cylinder or ellipse. Cell shape in square, circle, hexagon, triangle etc. The specification list in the website is just a part of our available specification, for your reference. We are also glad to accept customized product order.    

 

      Ceramic honeycomb structures are primarily produced from the material cordierite in either dense, porous or highly porous forms. Other materials can be supplied on customer request, Cellular ceramics provide the high surface area you need for catalyst, produce very low pressure drop,  low thermal expansion coefficient, strong thermal impact resistance, large surface area and good corrosion resistance.

Advantages

      of Cordierite Ceramic catalyst supports,  Cordierite Ceramic catalyst supports deliver cost savings and improve performance due to:

     1. Reduced pressure drop… cutting fan load for significant energy savings.
     2. Less volume… because they require less space. High surface area means high conversion efficiency in converters occupying small volumes.

     3. Lighter weight… so less structural support is required.
     4. Extended catalyst life… the low coefficient of thermal expansion gives them a high resistance to thermal shock, extending the catalyst lifetime.

     5. Thermal durability… enabling them to withstand operating temperatures of 2190 F (1200 C) and spikes to 2500 F (1410 C). In fact, the material strength actually increases with temperature, nearly doubling from ambient temperature to 2190 F.

     6. Increase surface area without paying a pressure drop penalty with thin wall products.

 

Catalyst carrier /substrate/support

              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.      More details...

 

Heat exchanger, Regenerative Thermal Oxidizer Applications

Heat exchanger, RTO,VOC

          Honeycomb Monoliths -Heat exchange media, Ceramic Heat Recovery Bed/ heat exchange beds, Thermal storage/ heat exchange elements/media,  Ceramic monoliths media to save energy in steel works and metallurgy industry, Regenerative thermal oxidizers (RTO). Honeycomb monolith is the key components of the thermal storage style furnace, it is extensively used in many kinds of heater, sirocco furnace, heat treatment furnace, cracking column, roaster, melting furnace, balance heating stove and etc. This technology can save more than 40-70% of energy.

        Volatile organic compounds VOC can be removed from waste gases by treatment through a regenerative thermal oxidizer (RTO). An RTO contains a ceramic heat exchanger bed that is utilized for the preheating and cooling of the waste gases before the gases enter and exit the combustion chamber, respectively. Honeycomb monoliths provide a more efficient alternative to other ceramic media, such as saddles or balls, that have conventionally been used in RTOs

      Ceramic honeycomb materials are mainly utilized in heat recovery unit of RTO s instead of ceramic saddles.

Ceramic filter plate for cast

         
Ceramic honeycomb Filters slice for the melting of metal in metallurgy /foundry industry, filters are in round slice shape etc. Feature: High Mechanical intensity , heat-resistant characteristic, able to get rid of the metal impurity, refractory scrap, solid refractory alloy, sinter, in the molten metal liquid when casting the products,  Reduce the air vent of castings, raise the quality of casting, reduce and cast the cost, Raise productivity. So our ceramic filters are extensively applied in the metallurgy plant of casting /foundry of steel, iron, copper and aluminum. Performance:

(1)The utilization ratio increasing           5-10%
(2)Casting tired intensity increases by 15.5%
(4)Spend 1700 ℃ fire-resistant
(5)Thermal shock, Heat impact resistant:not break cooling from 1200℃  by cold water for 5 times;
(6)Coefficient of thermal expansion : (1000℃) 1.6~5.4*10-6/℃;
(7)Compressive strength in the direction of axis >2~5MPa;
(8)Bulk density: ≥0.6~1g/cm3, Water absorption25±2%。
