A process for reducing content of sulphur compounds and polyaromatic hydrocarbons in a hydrocarbon feed having a boiling range between 200.degree.C and 600.degree.C, which process com- prises in combination contacting the feed and hydrogen over a hydrotreating catalyst and hydrotreating feed at hydro- treating conditions, cooling the hydrotreated effluent and hydrogen-rich gas from the hydrotreating reactor contacting said effluent and hydrogen gas over a hydrotreating cata- lyst in a post-pretreatment reactor at a temperature suffi- cient to lower the polyaromatic hydrocarbon content.
