Abstract: The invention provides a process for the preparation of a gas oil fraction comprising the steps of: (a) providing a stream of a first hydrocarbon product of which a major portion of the hydrocarbons have a boiling point in the range of from 370-540° C. and a stream of a second hydrocarbon product of which a major portion of the hydrocarbons have a boiling point of less than 370° C.

Abstract: A process or hydrotreating a hydrocarbon oil that employs a first reactor and a second reactor. The hydrocarbon oil is hydrotreated in the first reactor with a first hydrotreating catalyst in the presence of a first stream of hydrogen-containing gas to obtain a first effluent. The first effluent is separated using a stripping column to provide a hydrotreated hydrocarbon oil and used hydrogen-containing gas. A second stream of hydrogen-containing gas is heated within a section of a heating device arranged upstream of the first reactor to obtain a stream of heated hydrogen-containing gas. The stream of heated hydrogen-containing gas is contacted in the second reactor in the presence of at least part of the hydrotreated hydrocarbon oil with a second hydrotreating catalyst to obtain a second effluent which comprises a further hydrotreated hydrocarbon oil.
