Process for reducing content of sulphur compounds and poly-aromatic hydrocarbons in a hydrocarbon feed

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.

1 . A process for reducing content of sulphur compounds and polyaromatic hydrocarbons in a hydrocarbon feed stock having a boiling range between 200° C. and 600° C., which process comprises the steps of 
 (a) contacting the feed stock with hydrogen over a hydrotreating catalyst at conditions being effective in hydrotreating and obtaining an hydrotreated effluent with the hydrotreated feed stock, hydrogen sulphide and hydrogen,    (b) cooling the effluent, and    (c) contacting the effluent with a hydrotreating catalyst at conditions being effective in hydrogenation of polyaromatic hydrocarbons.
