Abstract
The invention concerns a process for eliminating arsenic from a hydrocarbon cut in which said cut is brought into contact with an absorption mass that is at least partially pre-sulfurized and comprises a support and lead oxide. The support, for example alumina, or said mass preferably has a specific surface area in the range 10 to 300 m /g, a total pore volume in the range 0.2 to 1.2 cm /g and a macroporous volume in the range 0.1 to 0.5 cm /g. The lead content of said mass, expressed as lead oxide, is preferably in the range of 5% to 50% by weight. The fraction of the sulfurized mass preferably represents at least {fraction (1/20)}th of the total volume of the absorption mass.
