Catalytic Converters and Other Emission Control Devices

Aldehyde and BTX Emissions from a Light Duty Vehicle Fueled on Gasoline and Ethanol-Gasoline Blend, Operating with a Three- Way Catalytic Converter

The current work is aimed at the experimental investigation of the aldehyde and BTX (benzene, toluene and Xylene) pollutants emitted from a light duty spark ignition (SI) vehicle fueled on gasoline and ethanol-gasoline blended fuel, operating with a three-way catalytic converter (TWC). At the same time, the specific reactivity (SR) of these pollutants has also been addressed in this paper. The ...

Diesel Emission Control in Review

This summary covers the developments from 2006 in diesel regulations, engine combustion, and NOx and PM remediation. Regulatory developments are now focused on Europe, where light-duty Euro 5 and 6 regulations have been proposed for 2009 and 2014, respectively. The regulations are lass stringent than those in the US, but options exist for adopting European vehicles for the US market. Europe is ...

Monolithic Three-way Palladium Catalytic Converters for Automobile Exhaust Emission Control

This article presents the research results on production and performance of palladium-only catalytic converters. Monolith is used as the catalyst carrier and gamma alumina as the substrate. Dipping method is used for monolith washcoating. Palladium as the active metal is impregnated on gamma alumina using wet impregnation to produce catalyst samples. The effects of factors such as percent solid...

Modeling Transport Phenomena in Selective Catalytic Reductant Catalytic Converter with NH3 as Reductant for NO Degradation

In the current study, reduction of nitrogen oxide from exhaust gas in the presence of NH3 as reductant on selective catalytic reductant (SCR) impregnated catalytic converter was simulated using Comsol© software. Mass transfer (one-dimensional) and heat transfer (three-dimensional) governing equations were taken into account to model the unsteady state behavior of the catalytic converter. Modeli...
