Abstract: A process for reducing content of sulphur compounds and polyaromatic hydrocarbons in a hydrocarbon feed having a boiling range between 200° C. and 600° C. is disclosed. The process comprises in combination contacting the feed and hydrogen over a hydrotreating catalyst and hydrotreating feed at hydrotreating conditions, cooling the hydrotreated effluent and hydrogen-rich gas from the hydrotreating reactor and contacting the effluent and hydrogen gas over a hydrotreating catalyst in a post-pretreatment reactor at a temperature sufficient to lower the polyaromatic hydrocarbon content.

Abstract: Described herein is a combined process for improved hydrotreating of diesel fuels, in which the feed to be hydrotreated is pretreated with a selective adsorbent prior to the hydrotreating step to remove polar materials, especially nitrogen containing compounds (N-compounds). The selective adsorption process can employ either liquid or solid adsorbents. After contact of the adsorbent with the diesel fuel feed, the adsorbent containing undesired polar compounds is separated from the diesel fuel. The separated adsorbent is then subjected to a two step procedure for regeneration.
