Alumina-supported In2O3, Ga2O3 and B2O3 were investigated as catalysts for lean NOx reduction with DME as reducing agent and compared to pure Al2O3 and In2O3. The In2O3-promoted alumina catalysts showed the highest NOx conversion at low temperatures,

The highly oxygenated hydrocarbon triethylene glycol dimethyl ether or triglyme (CH3O-(C2H4O-)(3)CH3) was found to efficiently reduce NOx under lean conditions over Ag/Al2O3, but gave a low NOx conversion over Cu-ZSM-5. Furthermore, triglyme showed a

Commercial Cu-ZSM-5- and Ag/Al2O3-based lean NOx catalysts were evaluated in a synthetic exhaust gas bench with the fuels RME, B30, B15, Agrodiesel 15, GTL, NExBTL, and MK1 as reducing agents. The influence of reductant was larger for Ag/Al2O3, albei

A range of ethers, alcohols and alkanes were compared as reducing agents for NOx over a Cu-ZSM-5 lean NOx catalyst. The nature of the reducing agent was found to determine the degree of NOx reduction. Methanol and DME were virtually inactive as reduc

Commercially available lean NOx catalyst and lean NOx adsorber samples were tested in a synthetic exhaust gas bench with DME as reducing agent. The LNA catalyst gave a very high NOx conversion (> 80 %) over a wide temperature range (275–450°C), an

One possible way to reduce NO x in lean exhausts is by using NO x trap catalysts. This paper addresses storage of NO x on such catalysts at temperatures below the catalyst light-off. Experiments carried out on commercial samples in synthetic exhausts
