PROCESS FOR REMOVING MERCURY OR ARSENIC FROM A FLUID IN THE PRESENCE OF A MERCURY AND / OR ARSENIC CAPTATION MASS

摘要

The invention relates to a method for removing mercury or arsenic in a fluid in the presence of a solid mercury and / or arsenic uptake mass. BR/ Said mass contains copper and sulfur at least partly in the form of copper sulphide and results from (a) the incorporation of a copper compound, other than a sulphide, on a solid mineral support, (b) a possible calcination of the product obtained in step (a), contacting the product obtained previously with elemental sulfur and (d) a heat treatment. / P
