Activation noble metal catalysts for use in hydrodehalogenation of halogen-substituted hydrocarbons containing fluorine and at that least one more halogen.

摘要

DESCRIBED PROCESS FOR TREATING CATALYST OF METAL SUPPORTED NEW OR OFF CONTAINING NOBLE METAL TO PREPARE SAID CATALYST FOR USE IN HIDRODESHALOGENIZACION of a compound having the formula: CNHMFPXQ, where each X is independently selected from Cl and Br, wherein n is an integer from 1 to 6, m is an integer from 0 to 12, p is an integer from 1 to 13, q is an integer from 1 to 13 and wherein M + P + Q EQUALS 2N +2 saturates FOR BEING acyclic M + P + Q EQUALS 2N For saturated compounds which are cyclic olefin COMPOUNDS AND ARE acyclic and M + P + Q EQUALS 2N-2 for olefinic compounds that are cyclic comprising the commissioning phase contacting said catalyst with a gas-containing CHLORINE atmosphere at a temperature of 100 (degrees) CA 400 (degrees) C for a time sufficient to improve the catalytic activity of SAME FOR SUCH HIDRODESHALOGENIZACION. ALSO DESCRIBED THE PROCESS FOR CATALYTIC HIDRODESHALOGENIZACION characterized by the use of a catalyst supported metal METAL CONTAINING NOBLE HAS BEEN CONTACTED an atmosphere containing chlorine.
