Abstract

The invention describes a process for the capture of organometallic impurities in a hydrocarbon feedstock of gasoline type containing olefins and sulfur, in which a capture body is brought into contact with the feedstock to be treated and a stream of hydrogen, said capture body comprises an active phase based on nickel oxide particles with a size of less than or equal to 15 nm, said active phase not comprising other metal elements of Group VIb or Group VIII, which are deposited on a porous support chosen from the group consisting of aluminas, silica, silicas/aluminas, or also titanium or magnesium oxides, used alone or as a mixture with alumina or silica/alumina.
