Abstract
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.
Claims9
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
- contacting the feed and hydrogen in a first step over a hydrotreating catalyst, hydrotreating the feed at hydrotreating conditions, and obtaining a hydrocarbon effluent containing hydrogen and hydrogen sulphide;
- cooling the effluent;
- and
- contacting the cooled effluent with a hydrotreating catalyst in a post treat step at conditions being effective in reduction of content polyaromatic hydrocarbon in the hydrocarbon feed.
