Product specs
Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Voc Catalysts. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
This product family includes monoliths for several distinct exhaust and waste-gas treatment functions: CDPF particulate filtration, diesel oxidation catalyst (DOC), urea-SCR NOx treatment, and VOC catalytic oxidation.
Available variants should be selected by treatment function rather than treated as interchangeable components. CDPF variants use a wall-flow structure to capture particulate matter from diesel exhaust.
The stated CDPF options include cordierite and silicon carbide constructions, with cylindrical and selected square formats. The product information associates these variants with reducing PM and PN emissions.
DOC variants are described for oxidation treatment of HC, CO and the soluble organic fraction in diesel exhaust. They are also intended to support CDPF regeneration by oxidizing NO to NO2 for passive soot regeneration or oxidizing fuel-derived hydrocarbons to raise the CDPF inlet temperature for active regeneration.
SCR options include vanadium-, copper- and iron-based variants. The stated function is NOx purification using urea-SCR technology. Available , so the required SCR chemistry must be specified during technical selection.
The VOC monolith uses modified alumina and rare-earth oxygen-storage material as a secondary substrate, with platinum and palladium identified as the principal active ingredients.
It is intended for catalytic oxidation of industrial volatile organic waste gases, including streams containing carbon monoxide, aromatic hydrocarbons, hydrocarbons and oxygen-containing derivatives.
Listed application sectors include food processing, chemicals, printing, machinery, auto to 330.2 mm for DOC and SCR variants, and from 143.8 to 330.2 mm for CDPF variants. Listed heights range from 76.2 to 177.8 mm for CDPF and selected SCR products, and from 76.2 to 152.4 mm for DOC and vanadium-SCR products.
Square formats and special customized sizes are also described. Depending on the variant, listed . Before procurement, buyers should confirm the required treatment function, catalyst chemistry, substrate construction, shape, exact diameter or square dimensions, height and CPSI.
The engine type, exhaust composition, operating-temperature profile, flow rate, pressure-drop limit, regeneration strategy and required emissions-validation method are not fully defined in the supplied product information and should therefore be reviewed for the specific project.
Buyers should also request confirmation of which stated emission-stage capability applies to the selected formulation and size rather than assuming every variant meets every listed stage.
