Process for the manufacture of lubricating oils |
摘要 |
The present invention provides for a process for reducing the pour point of a hydrocarbon feedstock containing nitrogen- and sulfur-containing impurities. The hydrocarbon feedstock is contacted with hydrogen and a hydrotreating catalyst under hydrotreating conditions whereby a portion of the nitrogen- and sulfur-containing compounds are converted to hydrogen sulfide and ammonia. A portion of the hydrotreater effluent is then passed to a dewaxing zone and contacted with hydrogen under dewaxing conditions in the presence of a dewaxing catalyst containing a borosilicate molecular sieve on silica-alumina-containing matrix.
