Method for trapping mercaptans using macropore trapping mass and mesopore trapping mass

Abstract

A process for capturing mercaptans contained in a sulfur-containing hydrocarbon feedstock, the process being carried out at a temperature between 40°C and 250°C, a pressure between 0.2MPa and 5MPa, and an hourly space velocity, defined as the volumetric flow rate of the feedstock at the inlet per volume of the capture mass, of 0.1 h -1 ~50h -1 in the presence of a capture mass comprising an active phase based on at least one Group VIII, IB or IIB metal and a mesoporous or macroporous support, said support being selected from the group consisting of alumina, silica, silica-alumina and clay, said capture mass being 120 ml. 2 / g~350m 2 / g specific surface area, The volume of mesopores having a diameter of 2 nm or more and less than 50 nm corresponds to 40% by volume to 70% by volume of the total pore volume of the capture mass; The volume of macropores having a diameter of 50 nm or more corresponds to 30% to 60% by volume of the total pore volume of the capture mass; process.
