A catalytic after treatment system for lean HC-SCR was constructed of two different catalyst beds, e.g. of a Ag/alumina and Cu-ZSM-5 catalyst (cascade concept). The improved activity especially at low temperature range was found to be due to the synergetic effect of the two catalysts, which combines the transformation of the feed gas over Ag/alumina to such compounds that are highly reactive
Abstract. Several catalysts based on transition metals (Cu, Co, Fe) and different supports (ZSM-5, activated carbon, Al 2 O 3) have been tested by Temperature-Programmed Reaction (TPR) experiments for the selective catalytic reduction of NO x with propene in the presence of excess oxygen, simulating lean-burn conditions. The activity order with respect to the metal was Cu∼Fe>Co for all
Central serous retinopathy (CSR), also known as central serous chorioretinopathy (CSC or CSCR), is an eye disease that causes visual impairment, often temporary, usually in one eye. When the disorder is active it is characterized by leakage of fluid under the retina that has a propensity to accumulate under the central macula.

The DeNO X efficiency of the 5L fresh catalyst was in the range of 0-25% without hydrogen, but it increased to 14-79% when the hydrogen was added to the feed stream. The final efficiency was a function of the hydrocarbon and hydrogen concentrations in the exhaust gas mixtures and the HC-SCR inlet temperatures.
Oct 08, 2017 · With a growing concern to lower greenhouse gas emissions from road transportation, lean burn and diesel engines will keep playing an important role in the future. Development of a highly efficient and durable process to reduce NOx to N2 becomes a challenging issue especially in the presence of ample O2 concentration as in lean burn exhaust. One way to reduce NOx emissions in lean exhaust is

Ag/Al2O3 catalysts (2 wt% Ag) have been prepared and calcined at different temperatures to render catalysts with different silver particle size or silver configuration. The differences in activity and selectivity of these catalysts are related to the activity for oxidation of NO and hydrocarbons, the NOx storage properties, and to the oxidation state of silver.
An exhaust aftertreatment system is provided with a first SCR catalyst, a NOx adsorber-catalyst, and an ammonia-SCR catalyst. The first catalyst is generally a hydrocarbon-SCR catalyst, but can be a carbon monoxide-SCR catalyst or a hydrogen-SCR catalyst. The first catalyst is functional to reduce NOx in lean exhaust using the corresponding reductant.
