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 covers CDPF, DOC, SCR and VOC catalyst elements in square or cylindrical configurations. The appropriate variant should be selected according to the exhaust stream, target pollutant, operating conditions and after-treatment system design.
CDPF variants are described for capturing particulate matter in diesel exhaust. Cordierite CDPF units use a wall-flow structure and are offered in 200 or 300 CPSI configurations. Silicon carbide CDPF variants are also listed at 200 or 300 CPSI.
The stated dimensional range is 143.8–330.2 mm in diameter and 76.2–177.8 mm in height, with a 150 × 150 mm square format also described for cordierite units. DOC variants are intended for oxidation treatment of HC, CO and the soluble organic fraction in diesel exhaust.
The description also identifies DOC functions supporting passive CDPF regeneration through NO oxidation and active regeneration by oxidizing fuel-derived hydrocarbons to raise CDPF inlet temperature.
Listed DOC options include diameters of 118.4–330.2 mm, heights of 76.2–152.4 mm, 100 × 100 mm and 150 × 150 mm square formats, and . SCR options include vanadium, copper and iron variants. The vanadium SCR description identifies urea-SCR treatment of NOx in diesel exhaust.
Listed SCR formats include cylindrical and square elements, with . The VOC version is described for catalytic oxidation of industrial volatile organic waste gas.
It uses modified alumina and rare-earth oxygen-storage material as a secondary substrate, with platinum and palladium identified as the principal active ingredients. Listed VOC formats are 100 × 100 mm and 150 × 150 mm, with lengths from 50 to 300 mm and , 100, 200 or 300 CPSI.
The stated application areas include food, chemical, printing, machinery, auto ounds such as carbon monoxide, aromatic hydrocarbons, hydrocarbons and oxygen-containing derivatives.
Before procurement, the buyer should confirm the exact catalyst technology, substrate, geometry, dimensions, CPSI, pollutant profile and engine or process operating window.
Also request confirmation of the required emissions target, catalyst loading, pressure-drop limits, temperature range, housing or canning requirements, expected service conditions, drawing tolerances and validation method.
Any certification requirement, customization scope, production schedule, packaging arrangement and after-sales terms should be verified for the specific ordered configuration.
