Process for reduction of content of sulphur compounds and poly-aromatic hydrocarbons
in distillate fuels |
(57) A process for reducing content of sulphur compounds and polyaromatic hydrocarbons
in a hydrocarbon feed having a boiling range between 120°C and 450°C, which process
comprises in combination
- contacting the feed and hydrogen over a hydrotreating catalyst and hydrotreating feed
at hydrotreating conditions, cooling the effluent consisting of hydrocarbon, polyaromatic
hydrocarbons, hydrogen sulphide and hydrogen-rich gas from the hydrotreating reactor,
- contacting said effluent and hydrogen gas over a hydrotreating catalyst in a post
treat reactor at a temperature appropriate to lower the polyaromatic hydrocarbon content.
