METHOD FOR PRODUCING A FORMED CATALYST OR FORMED CATALYST SUPPORT

摘要

The present invention relates to a method for producing formed catalysts or formed catalyst supports, to the catalysts or catalyst supports obtainable thereby and a method for the catalytic treatment of carbon compounds, preferably for the oxidation or hydrogenation of carbon compounds, preferably aromatic hydrocarbons, in particular nitroaromatics, or unsaturated hydrocarbons; the catalyst or support being prepared by: a) providing a suspension comprising at least one polysaccharide and at least one precursor of a catalyst or at least one precursor of a catalyst support, b) introducing the suspension of step a) into an acidic medium comprising at least one monovalent acid to form mouldings, c) drying the mouldings obtained in step b) and d) calcining the mouldings dried in step c) at temperatures from 350 to 1300°C to obtain the formed catalysts or formed catalyst supports.
