    Abstract: In a process for hydrogenating unsubstituted monocyclic or polycyclic aromatics or monocyclic or polycyclic aromatics substituted by at least one alkyl group, amino group or hydroxyl group or a combination of two or more thereof to form the corresponding cycloaliphatics by means of gaseous hydrogen in the presence of at least one catalyst in a reaction column (4) in which the reactants are passed over the catalyst(s) (5) fixed in the reaction column (4), the cycloaliphatics are taken off at a side offtake (14) or from the bottom of the column (6) through a line (8) or at the side offtake (14) and from the bottom of the column (6) through a line (8).

    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).
