Abstract: A process for the selective hydrogenation of aliphatic or aromatic substrates under supercritical or near critical conditions. Hydrogenation is effected using a heterogeneous catalyst in a continuous flow reactor containing a supercritical or near critical reaction medium and selectively product formation is achieved by varying one or more of the temperature, pressure, catalyst and flow rate.

Abstract: The invention relates to a process for the selective catalytic hydrogenation of the carbonyl group of aromatic aldehydes of the formula in which X can be a carboxyl group, a methyl group or halogen, to give the corresponding alcohols and methyl compounds. The catalytic hydrogenation is carried out with the addition of a solvent, if appropriate in the presence of organic acids, on a shaped supported catalyst containing a metal from the platinum group on a titanium oxide support in the presence of hydrogen at partial pressure of hydrogen of 5 to 50 bar and temperatures of from 100 to 300@C.

Abstract: The invention relates to a method for removing an organic compound having one or more positive charges from an aqueous solution. Said method consists of the following steps a) the aqueous solution containing the organic compound, and a hydrophobic organic solution which contains a hydrophobic liquid cation exchanger having one or more negative charges and a negative total charge, are provided, b) the aqueous solution and the organic solution are brought into contact with each other and c) the organic solution is separated from the aqueous solution.

Abstract: The invention relates to a high performance catalyst containing a layer on an inert carrier body comprising noble metals from the platinum group deposited on support materials. The catalyst is characterised in that, the layer comprises platinum deposited in a washcoat consisting of A1203 which is stabilized with lanthana (La203), ceria (CeO2), which is stabilized with zirconia (ZrO2) and praseodymium (Pr6011). The supprot is promoted by sulfur-containing compounds which come from at least one of following compounds: platinum sulfite (PtSO3), sulfuric acid (H2SO4), ammonium sulfate ((NH4)2SO4), titanium oxysulfate (TiOSO4), titanium sulfate (Ti2(SO4)3), and zirconium sulfate (Zr(SO4)2).
