| Zusammenfassung: | Process for the catalytic hydrotreating of a hydrocarbon feed stock containing silicon compounds comprising the steps of
contacting the feed stock in presence of hydrogen with a first hydrotreating catalyst being arranged in at least two reactors being connected in series at an outlet temperature of up to 410°C to reduce content of the silicon compounds in the feed stock;
cooling of the feed stock such treated to a temperature of between 280° and 350°C; and
contacting the cooled feed stock with a second hydrotreating catalyst at conditions being effective in reduction of sulphur compound and nitrogen compound concentration. |
