(57) [Summary]nA carbon support having an ash content (based on the weight of the support) of less than about 0.2% by weight is prepared from 5-95 parts by weight of gold and a total of 95-5 parts by weight of ruthenium, rhodium, palladium, osmium, iridium and / or platinum. The impregnated metal combination is impregnated with the impregnated carbon combination, and the impregnated carbon combination is treated and the composition is dried to obtain the above combination in a reduced state, the impregnation step of the treatment being 350 ° C. Discloses a metal-supported hydrogen dehalogenation catalyst supported on carbon, which is produced by the method performed in Example 1. The advantageous use of catalysts for the catalytic hydrocracking of fluorohalocarbons and fluorohalohydrocarbons is also disclosed. |
