Abstract: Process for the preparation of a supported catalyst for the polymerisation of alpha -olefins, in which (1) a support gel containing silicon dioxide is prepared by (1.1) introducing a sodium or potassium waterglass solution into a rotating stream of an aqueous mineral acid both longitudinally and tangentially to the stream, spraying the silicic acid hydrosol thus formed in droplet form into a gaseous medium, allowing it to solidify into a hydrogel and freeing the hydrogel thus obtained of salt by washing without prior aging, (1.2) drying the hydrogel resulting from (1.1) to form the support gel, and (2) the support gel (1) is loaded with chromium trioxide or a chromium compound which can be converted into chromium trioxide under the conditions of the process step (3), which results in a chromium-containing support gel, and (3) the chromium-containing support gel (2) is heated in an anhydrous gas stream containing oxygen in a concentration of over 10% by volume for from 10 to 1000 minutes at from 400 to 1100 DEG C, the hydrogel resulting from the process step (1.1) being dried in the process step (1.2) over a time of not more than 60 seconds in a shaping flash dryer at an inlet temperature of from 80 to 400 DEG C .

Abstract: The invention relates to a method for cleaning crude terephthalic acid by means of catalytic, hydrogenating aftertreatment using a catalyst material containing at least one hydrogenation metal applied to a carbon carrier consisting of carbon fibres. The invention also relates to a catalyst consisting of the at least one catalyst material containing the at least one hydrogenation metal applied to the carbon fibres, the BET surface of the carbon carrier being

Abstract: A catalyst packing which can be produced by vapor deposition and/or sputtering of at least one substance active as catalyst and/or promotor onto woven or knitted fabrics or sheets as support material is used in a process for catalytic distillation in which a heterogeneously catalyzed reaction is combined with a simultaneous distillation or rectification over the catalyst packing.

Abstract: A process for the purification of crude terephthalic acid comprises catalytic hydrogenation using a catalyst material (I) comprising a ca bon supported hydrogenation metal whereby the carbon support comprises carbon fibers. Independent claims are included for: (1) the catalyst material (I) whereby the carbon support has a BET surface area of less than 500 Micro 2>/g; (2) a reactor (II) containing a flat catalyst material in the form of cloth, textile and/or felt comprising a hydrogenation metal applied to carbon fibers and having at least two edges opposite to each other to which the catalyst material is stably affixed or containing the catalyst material in the form of parallel fibers or bands; and (3) a process for the selective hydrogenation of carbon-carbon double or triple bonds and/or hydrogenatable functional groups using the catalyst material (I) or reactor (II).
