Abstract: A process for the treatment of a light cracked naphtha is disclosed wherein the light cracked naphtha is first subjected to thioetherification and fractionation into two boiling fractions. The lower boiling fraction is removed as overheads for later recombination with the product and the higher boiling fraction is combined with a heavy cracked naphtha and subjected to simultaneous hydrodesulfurization and fractionation to separate the higher boiling fraction from the heavy cracked naphtha which is recycled. The recycled heavy cracked naphtha is eventually desulfurized and hydrogenated to produce a clean solvent which washes the catalyst and extends catalyst life.

Abstract: A process for concurrently fractionating and hydrotreating a full range naphtha stream. The full boiling range naphtha stream is subjected to simultaneous hydrodesulfurization and splitting into a light boiling range naphtha and a heavy boiling range naphtha, which have been treated to convert mercaptans in the fractions to H2S, which is separated with and separated from the light naphtha which is further hydrodesulfurized by contacting the light boiling range naphtha with hydrogen in countercurrent flow in a fixed bed of hydrodesulfurization catalyst to remove recombinant mercaptans which are formed by the reverse reaction of H2S with olefins in the naphtha during the initial hydrodesulfurization wherein the improvement comprises fractionating said portion of light boiling range naphtha to remove a lighter fraction thereof from said countercurrent flow reactor before contact of said lighter fraction with said fixed bed catalyst, because the lighter fraction is substantially free of mercaptans and is not benefitted by further treatment.

Abstract: Processes for the desulfurization of a cracked naphtha by the reaction of hydrogen with the organic sulfur compounds present in the feed are disclosed. In particular, processes disclosed herein may use one or more catalytic distillation steps followed by further hydrodesulfurization of the naphtha in a fixed bed reactor. It has been found that the formation of recombinant mercaptans in the fixed bed reactor effluent may be reduced or eliminated by reducing the concentration of hydrogen sulfide and/or olefins at the exit of the fixed bed reactor. The reduction or elimination in the formation of recombinant mercaptans may be accomplished by recycling a select portion of the fixed bed reactor effluent to the fixed bed reactor, where the select portion has a relatively low or nil concentration of olefins. Processes disclosed herein may thus facilitate the production of hydrodesulfurized cracked naphthas having a total sulfur content of less than 10 ppm, by weight.
