CLEAN AIR Lean NOx Catalyst System -Free NOx Abatement Technology

Clean Air innovation, accelerated SM Hydrocarbon Lean NOx Catalyst System Urea-Free NOx Abatement Technology

Forward thinking. Forward moving.

Next-generation NOx abatement

Growing emission control challenges require innovative solutions to meet the unique needs of established and emerging markets alike. Tenneco’s Hydrocarbon Lean NOx Catalyst (HC LNC) system provides a urea-free NOx abatement alternative for a wide range of applications and regions.

efficiency equivalent to that of liquid urea SCR without the associated challenges. Designed with a unique dual-reductant dosing capability, the HC LNC system offers significant flexibility. For applications with high duty cycles or that can maintain exhaust temperatures greater than 350°C, the system uses the vehicle’s on-board as the aftertreatment reductant to achieve up to 60% NOx conversion efficiency. To reach NOx conversion efficiencies greater than 95% or when exhaust temperatures An alternative to liquid-urea SCR, Tenneco’s range as low as 270°C, the HC LNC uses a HC LNC system uses fuel-based reductants to secondary, biorenewable reductant such as provide an excellent NOx abatement solution.
