Abstract (en)

A hydrocarbonaceous feedstock (8) is hydrocracked in a plurality of reaction stages by contacting the feedstock with a first hydrocracking catalyst (2) at elevated temperature and pressure in the presence of hydrogen (9) in a first reaction stage to yield a first effluent (10), mixing at least a liquid portion of the first effluent with a second effluent that originates from a second reaction stage (4), contacting the mixture obtained in a third reaction stage with a third hydrocracking catalyst (5) at elevated temperature and pressure in the presence of hydrogen to yield a third effluent (12), passing the third effluent to a separation stage where at least one top fraction and a residual fraction (19) are obtained and passing the residual fraction to the second reaction stage where it is contacted with a second hydrocracking catalyst at elevated temperature and pressure in the presence of hydrogen (20) to yield the second effluent.
