Abstract: The invention relates to a high performance catalyst containing a layer on a n 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 Al203 which is stabilized with lanthana (La2O3), ceria (CeO2), which is stabilized with zirconia (ZrO2) and praseodymium (Pr6O11). 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).

Abstract: A process for the alkylation of aromatic substrates under supercritical or near-critical reaction conditions is described. In particular, a method for performing Friedel-Crafts alkylation reactions is disclosed under those conditions. Friedel-Crafts reactions may be effected using a heterogeneous catalyst in a continuous flow reactor containing a supercritical or near-critical reaction medium. Selectivity of product formation can be achieved by varying one or more of temperature, pressure, catalyst, flow rates and also by varying the ratios of aromatic substrate to alkylating agent.

Abstract: Moldings are disclosed for use as a catalyst or catalyst support for hydrating olefin, such as ethylene and propylene. The moldings are based on a pyrogenically produced mixed oxide having the following physicochemical parameters:The moldings are produced by homogenizing pyrogenically produced mixed oxide as desired with water and one or more compounds selected from the group of methylcellulose, methylhydroxyethylcellulose, wax, polyethylene glycol, magnesium stearate or aluminium stearate; drying the product at a temperature of 70-150° C.; optionally comminuting to yield a powder; optionally compression molding the powder to yield moldings; and performing heat treatment for a period of 0.5 to 10 hours at a temperature of 400 to 1200° C. Prior to drying, the mixture may also be subjected to kneading and/or shaping processes and extruded.
