    摘要: The present invention concerns a process for selectively removing nitrogen oxides (NOx) from exhaust or flue gasses, especially from gases arising from the burning of biomass, combined biomass-fossil fuel and from waste incineration units, and a catalyst for this process. The process relates to the selective catalytic reduction (SCR) of NOx with ammonia as reductant which is the most common method to catalytically reduce NOx in flue gasses from stationary sources. SCR systems are designed to clean the nitrogen dioxide (NO 2 and nitrogen oxide (NO) out of flue gasses. The present invention relates to a process for the selective removal of nitrogen oxides in the presence of ammonia from gases containing a significant amount of alkali metal and/or alkali-earth compounds which process comprises using a catalyst combined of a) a formed porous superacidic support b) a metal oxide catalytic component deposited on said support selected from the group consisting of Cu, V, Fe, Cr, Mn, Mo and mixtures thereof. The support can e.g. be obtained by the adsorbing of sulfate ions onto amorphous or crystalline inorganic oxide of Zr, Ti, Fe, Sn, Si, Al, and Hf, followed by calcination in air.

    摘要: The present invention concerns a catalyst system in particular a catalyst system comprising Palladium (Pd), a zwitterion and/or an acid-functionalized ionic liquid, and one or more phosphine ligands, wherein the Pd catalyst can be provided by a complex precursor, such as Pd(CH3COO)2, PdCI2, Pd(CH3COCHCOCH3), Pd (CF3COO)2, Pd(PPh3)4 or Pd2(dibenzylideneacetone)3. Such catalyst systems can be used for e.g. alkoxycarbonylation reactions, carboxylation reactions, and/or in a co-polymerization reaction, e.g. in the production of methyl propionate and/or propanoic acid, optionally in processes forming methyl methacrylate and/or methacrylic acid. Catalyst systems according to the invention are suitable for reactions forming separable product and catalyst phases and supported ionic liquid phase SILP applications.
