Procedure for the fixed-bed sweetening of petroleum fractions

摘要

The invention relates to a process for the sweetening of a petroleum fraction in a fixed catalytic bed in the presence of an oxidizing agent, by catalytic oxidation of the mercaptans which it contains, in the presence of a catalyst in the form of a support impregnated with a metal chelate and in the absence of an aqueous base, the water content of the support is maintained within a predetermined range of values by action on the solvent power of the feedstock for the water of the support as a function of temperature.
