Zusammenfassung:The present invention describes a process for the preparation of a pt catalyst supported on carbon, comprising the preparation of an acid aqueous solution of a salt of pt, and the impregnation with said solution of a carbon with marked basic or neutral character, the which has a desorption of co2 below 100 μ moles/gram of carbon, as well as a catalyst obtainable according to said process and the use of said catalyst in the treatment of residual gaseous effluents contaminated with chloromethanes . (Machine-translation by Google Translate, not legally binding) La presente invención describe un procedimiento para la preparación de un catalizador de Pt soportado sobre carbón, que comprende la preparación de una solución acuosa ácida de una sal de Pt, y la impregnación con dicha solución de un carbón con marcado carácter básico o neutro, el cual que presenta una desorción de CO{sub,2} inferior a 100 {mi}moles/gramo de carbón, así como un catalizador obtenible según dicho procedimiento y el uso de dicho catalizador en el tratamiento de efluentes gaseosos residuales contaminados con clorometanos.
