Abstract
The invention relates to a method for capturing organometallic impurities in a gasoline-type hydrocarbon feedstock containing sulfur compounds and olefins, wherein said feedstock is brought into contact with hydrogen and a capture mass comprising a nickel-based active phase, and a mesoporous and macroporous alumina substrate having a bimodal distribution of mesopores and wherein: —the volume of mesopores having a diameter greater than or equal to 2 nm and less than 18 nm corresponds to between 10 and 30% by volume of the total pore volume of said substrate; —the volume of mesopores with a diameter greater than or equal to 18 nm and less than 50 nm corresponds to between 30 and 50% by volume of the total pore volume of said substrate.
