PROCESS FOR THE CATALYTIC HYDROTREATING OF SILICON CONTAINING HYDROCARBON FEEDSTOCK

摘要

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.degree.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.degree. and 350.degree.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.
