The present invention relates to a kind of at least one hydroconversion reactions device for hydrocracking heavier hydrocarbon feeds, and at least one hydrotreating reactor for hydrotreatment heavier hydrocarbon feeds the method for heavier hydrocarbon feeds described in upgrading, described method comprises two or more catalyzer of preparation, often kind of catalyzer is prepared by one or more of catalyst precursor at least one specific preparation feedback device, described catalyst precursor contains the IIA that at least one is selected from the periodic table of elements, IIIB, IVB, VB, VIB, VIIB, VIII, the transition metal of IB or IIB race, each preparation feedback device is one or more hydrocracking or hydrotreating reactor feed, often kind of catalyzer contained in preparation feedback device is exclusively used in raw material described in hydrocracking or hydrotreatment.The method allows the product obtaining more high-quality under operate continuously condition. |
