Abstract: 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, PdCl2, 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.

Abstract: Cu/mordenite catalysts were found to be highly active for the SCR of NO with NH3 and exhibited high resistance to alkali poisoning. Redox and acidic properties of Cu/mordenite were well preserved after poisoning with potassium unlike that of vanadium catalysts. Fe-mordenite catalysts also revealed much higher alkali resistivity than that of commercial V2O5/WO3—TiO2 (VWT) SCR catalyst which is currently used for NOx abatement in stationary installations. Unique support properties like high surface area and surface acidity, which are not available in the commercial VWT catalyst, seem to be essential requirements for the high alkali resistance. Mordenite-type zeolite based catalysts could therefore be attractive alternatives to conventional SCR catalysts for biomass fired power plant flue gas treatment.

Abstract: The present invention concerns the selective removal of nitrogen oxides (NOx) from gases. In particular, the invention concerns a process, a highly alkali metal resistant heteropoly acid promoted catalyst and the use of said catalyst for removal of NOx from exhaust or flue gases, said gases comprising alkali or earth alkali metals. Such gases comprise for example flue gases arising from the burning of biomass, combined biomass and fossil fuel, and from waste incineration units. The process comprises the selective catalytic reduction (SCR) of NOx, such as nitrogen dioxide (NO2) and nitrogen oxide (NO) with ammonia (NH3) or a nitrogen containing compound selected from ammonium salts, urea or a urea derivative or a solution thereof as reductant.

Abstract: The present invention relates to biologically active compounds, particularly liquid compounds, which are immobilized on a solid carrier material, particularly on mesoporous silica. The compounds are non-covalently supported on the solid carrier material thereby forming stable, easily handled solids which have the further advantage that the adsorbed biologically active compounds have improved thermal stability compared with the non-adsorbed compounds, and that they are released rapidly and completely from the carrier material when placed in an aqueous environment.

Abstract: The present invention concerns a method of preparation of nanoparticular metal oxide catalysts having a narrow particle size distribution. In particular, the invention concerns preparation of nanoparticular metal oxide catalyst precursors comprising combustible crystallization seeds upon which the catalyst metai oxide is co-precipitated with the carrier metal oxide, which crystallization seeds are removed by combustion in a final calcining step. The present invention also concerns processes wherein the nanoparticular metal oxide catalysts of the invention are used, such as SCR (deNOx) reactions of nitrogen oxides with ammonia or urea as reductant, oxidations of alcohols or aldehydes with dioxygen or air to provide aldehydes, ketones or carboxylic acids, and photocatalytic oxidation of volatile organic compounds (VOCs).

Abstract: The catalytic behaviour of vanadia-supported zeolite catalysts with different SiO2/Al2O3 ratios was tested for the SCR of NO with ammonia. The SCR activity was found to be directly correlated to the total acidity of the catalysts. On the surface of these zeolites the V2O5 was highly dispersed and amorphous in nature. After the impregnation with vanadium and subsequent poisoning with potassium oxide not much change in micro-pore structure of HZSM5 was observed by N2 adsorption studies. Interestingly, potassium-doped HZSM5 and HMORDENITE catalysts showed high resistance to deactivation because of the unique nature of the material exhibiting higher surface area and acidity than the conventional V2O5—WOx/ZrO2 or TiO2 catalysts. Consequently, a possible application of these alkali-tolerant SCR catalysts in biomass fired power plants can be envisaged.
