catalyst for hydierenden abreicherung of cfcs and halons in gas phase

摘要

The invention relates to a catalyst and method for selective hydrogenated depletion of chlorofluorocarbons (CFC's) and halons from gas phases. The aim of the invention is to develop a catalyst and method which permit the removal of unwanted chlororganic parts to the greatest extent by sparing additionally present gases such as fluorocarbon in order to make very expensive reprocessing technology unnecessary. To this end, the invention provides a supporting material on which an active component mixture is fixed. Said active component mixture contains at least one metal composition of general formula OsaRubXcYd, in which (X) represents additional metals of subgroup VIII of the periodic table of elements; (Y) represents metals of subgroups III or IV and rare-earth metals; (a) represents a number ranging from 0 to 100; (b) represents a number ranging from 0 to 100; (c) represents a number ranging from 0 to 100; and (d) represents a number ranging from 0 to 100, whereby (a) plus (b) cannot equal zero.
