comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولCatalytic reduction of nitric oxide by carbon monoxide.
The reduction of nitric oxide by carbon monoxide, reaction (l), mediated by metal complexes has attracted great attention recently due to its relevance to the control of air pollution and the intrinsic interest in the mechanism of N20 and C02 formation. 1-7 While a number of catalyst systems for reaction (1) have been reported, only the RhIILRhI and the PdC12CuCI2. systems rapidly catalyse the ...

Selective catalytic reduction of nitric oxide by methane over cerium and silver ion-exchanged ZSM-5 zeolites
A new catalyst comprising cerium and silver ion-exchanged ZSM-5 zeolite is reported in this paper, for the reduction of nitric oxide by methane in the presence of excess oxygen. The bi-cation exchanged Ce-Ag-ZSM-5 catalyst was very active for this reaction, while either Ce-ZSM-5 or Ag-ZSM-5 alone showed low activity. The presence of oxygen in the feed gas mixture enhanced the activity of the ca...
متن کاملSelective Catalytic Reduction: Exhaust aftertreatment for reducing nitrogen oxide emissions
Ways to reduce nitrogen oxide emissions In order to comply with the increasingly tough emission standards worldwide, engine manufacturers are forced not only to substantially reduce emissions of particulate matter (PM), but also emissions of nitrogen oxides. The main approach pursued by MTU is low-emission combustion, in other words an internal engine solution. However, this means taking into a...
