The present invention relates to a new strategy for capturing NOusing a two-step process.

[object Object]

The present invention concerns the absorption and desorption behavior of carbon dioxide (CO) using ionic liquids derived from amino acids adsorbed on porous carrier materials.

The disclosure concerns an improved method of preparation of nanoparticular vanadium oxide/anatase titania catalysts having a narrow particle size distribution. In particular, the disclosure concerns preparation of nanoparticular vanadium oxide/anatase titania catalyst precursors comprising combustible crystallization seeds upon which the catalyst metal oxide is coprecipitated with the carrier metal oxide, which crystallization seeds are removed by combustion in a final calcining step.

Method of preparation of nanoparticular metal oxide catalysts

The present invention concerns the absorption and in situ oxidation of nitric oxide (NO) in the presence of water and oxygen in ionic liquid compositions at ambient temperature.

Absorption and oxidation of NO in ionic liquids

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 metal 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).

Nanoparticular metal oxide/anatase catalysts

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 (NO) and nitrogen oxide (NO) with ammonia (NH) or a nitrogen containing compound selected from ammonium salts, urea or a urea derivative or a solution thereof as reductant.

Heteropoly acid promoted catalyst for SCR of NOx with ammonia

A process for continuous carbonylation of carbonylatable reactants with carbon monoxide in the gaseous phase in the presence of a catalyst, wherein said catalyst is a Supported Ionic Liquid-Phase (SILP) catalyst comprising a solution of a Group VIII metal in an ionic liquid confined on a support. The SILP catalyst offers a very large active catalyst area resulting in a very efficient use of catalyst material and a simple apparatus design.

Process for continuous carbonylation by supported ionic liquid-phase catalysis

The present invention concerns the selective removal of nitrogen oxides (NOx) from gasses. In particular, the invention concerns a process, a catalyst and the use of a catalyst 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 (i) a formed porous superacidic support, said superacidic support having an Hammett acidity stronger than Ho=&#x2212;12, and (ii) a metal oxide catalytic component deposited on said superacidic support selected from the group consisting of oxides of Fe, Cu, V, Cr, Mn, and any mixtures thereof.
