Catalysts for exothermic reactions conducted in a fixed bed, comprising an inert diluent constituted by metal granules in which the metal has a thermal conductivity of more than 0.5 W/cm/K, particularly catalysts for the oxychlorination of ethylene to 1,2-dichloroethane.

Catalysts for exothermic reactions on a fixed bed

A catalyst for the oxi-chlorination of ethylene to 1,2-dichloroethane which comprises cupric oxychloride (CuOHCl) as an active component. CuOHCl is preferably supported on a porous support such as alumina and used in fixed-bed oxi-chlorination processes.

Catalysts for the oxi-chlorination of ethylene to 1,2-dichloroethane

Hydrogenation catalysts comprising metallic palladium supported on activated carbon, wherein less than 50% by weight of the palladium is comprised within a surface layer with a depth of up to 50 microns, the remainder being comprised in a layer between 50 and 400 microns deep. The catalysts can be used in particular in purifying terephthalic acid obtained by oxidation of p-xylene.
