| Abstract | The present invention relates to a novel process for desulfurization of diesel with reduced hydrogen consumption. More particularly the subject invention pertains to an integrated process comprising diesel hydro de-sulfurisation (DHDS) or diesel hydrotreatment (DHDT) with reduced severity to desulfurize high sulfur (1.0-2.0 wt%) diesel stream to a much lower level of sulfur content of 350 - 500 ppm in the depleted diesel stream, followed by a novel adsorption procedure for effecting deep desulfurization to reduce overall sulfur content to less than 10 ppm with reduced hydrogen consumption, as compared to high severity DHDS or DHDT procedures of the prior art.
La présente invention concerne un nouveau procédé pour la désulfuration de gazole à consommation d'hydrogène réduite. L'invention concerne plus particulièrement un procédé intégré comprenant l'hydrodésulfuration du gazole (DHDS) ou l'hydrotraitement du gazole (DHDT) à sévérité réduite pour désulfurer un courant de gazole à haute teneur en soufre (1,0-2,0 % en poids) à un niveau de teneur en soufre beaucoup plus faible de 350-500 ppm dans le courant de gazole appauvri, puis un nouveau procédé d'adsorption pour une désulfuration profonde permettant de réduire la teneur en soufre totale à moins de 10 ppm avec une consommation en hydrogène réduite, par comparaison avec les procédés DHDS ou DHDT haute sévérité de l'art antérieur. |
