Abstract
A process for the hydroconversion of a hydrocarbon feedstock. The process includes contacting the hydrocarbon feedstock with a catalyst in a first hydrocracking section to obtain a first hydrocarbon effluent stream which is separated into a gaseous stream, a light liquid stream and a heavy liquid stream. These liquid streams are fractioned into a number of fractions of hydrocarbons including a fraction of hydrocarbons having a boiling point above 350° C. This fraction of hydrocarbons is contacted with a catalyst in a second hydrocracking section to obtain a second hydrocarbon effluent stream that is separated to obtain a gaseous stream, a light liquid stream and a heavy liquid stream. These liquid streams are fractioned into a number of fractions of hydrocarbons including a heavy fraction of hydrocarbons having a boiling point above 350° C. This fraction of hydrocarbons is split into a major stream and a minor stream with the major stream being recycled and the minor stream is recovered.
