HENTEKCAT’s Gas Catalyst division delivers high-performance catalytic solutions for gas purification, emission control, and process gas treatment across industrial, aerospace, and environmental applications. Our portfolio spans ozone abatement, carbon monoxide oxidation, hydrogen peroxide decomposition, oxygen removal, and selective hydrogenation – each engineered for reliability, efficiency, and cost-effectiveness.
The Three-Way Catalyst (TWC) is the cornerstone of gasoline emission control, simultaneously converting CO, HC, and NOx under stoichiometric operation (lambda = 1.00). Our TWC solutions cover port fuel injection (PFI), gasoline direct injection (GDI), and hybrid electric vehicles (HEV/PHEV).
Key Features:
Applications: Passenger cars, SUVs, light trucks, hybrids, and performance vehicles.
Our universal catalyst packages provide certified emissions performance for the aftermarket, small-volume OEM, and specialty vehicle markets. These pre-configured, application-flexible solutions are designed to meet emissions targets across a range of engine sizes and configurations.
Key Features:
Applications: Aftermarket replacements, classic car restorations, custom builds, small-volume OEM, and off-highway equipment.
The DOC is the first active device in diesel aftertreatment, converting CO and HC, oxidizing NO to NO₂, and generating exothermic heat for DPF regeneration.
Key Features:
Applications: On-highway trucks, buses, non-road machinery, marine, and diesel gensets.
The DPF traps soot and ash particles using a wall-flow substrate, achieving >99% filtration efficiency for all particle sizes including sub-23nm nanoparticles.
Key Features:
Applications: On-highway diesel, non-road machinery, marine, and diesel gensets.
SCR is the primary NOx reduction technology for diesel engines, using DEF (32.5% urea) to convert NOx into N₂ and H₂O with 90–99% efficiency.
Key Features:
Applications: On-highway diesel, non-road, marine, industrial, and diesel gensets.
Precision DEF dosing is critical for SCR performance. Our urea injection systems deliver accurate, reliable DEF metering across all operating conditions.
Key Features:
Applications: On-highway diesel, non-road, marine, and stationary diesel engines.
NOx sensors provide the essential feedback for SCR closed-loop control and OBD compliance, measuring NOx concentration in exhaust gas with exceptional accuracy.
Key Features:
Applications: On-highway diesel, non-road, marine, and industrial SCR systems.
For GDI engines, the GPF captures fine soot particles with >99% efficiency while maintaining low backpressure and passive regeneration.
Key Features:
Applications: GDI passenger cars, SUVs, hybrids, and performance vehicles.
Our VOC abatement systems provide destruction or recovery of volatile organic compounds from industrial exhaust streams.
Key Technologies:
Applications: Printing, coating, painting, chemical, pharmaceutical, and semiconductor industries.
Non-road equipment (construction, agriculture, mining, forestry, marine, gensets) faces extreme operating conditions. Our systems meet Stage V, Tier 4 Final, and China Stage IV standards.
Key Features:
Applications: Excavators, bulldozers, wheel loaders, tractors, combines, LHDs, haul trucks, ferries, tugs, and diesel gensets.
We manufacture ceramic (cordierite) and metallic (FeCrAlloy) honeycomb substrates for all aftertreatment applications.
Key Features:
Applications: TWC, DOC, SCR, GPF, DPF, and industrial catalysts.
Our in-house washcoat formulations provide the catalytic activity that defines performance. We engineer coatings for every application and regulatory target.
Key Features:
Applications: All catalytic aftertreatment systems.
Reliable oil supply is essential for turbocharger durability. Our oil feed and return lines ensure consistent lubrication and cooling.
Key Features:
Applications: Turbocharged gasoline and diesel engines, performance vehicles.
We provide complete, turnkey aftertreatment systems—from component selection and thermal management to mechanical packaging and system calibration.
Key Features:
Applications: All engine platforms, all fuel types, all regulatory scenarios.
