Hydrotreatment process for converting a heavy hydrocarbon fraction containing sulfur impurities and metal impurities to a lighter oil in at least two steps
A process for the hydrotreatment of a heavy hydrocarbon fraction containing sulfur and metal impurities comprises at least two steps: a first step using a catalyst comprising a low proportion of at least one metal of groups V, VI and VIII, said catalyst being in the form of a plurality of juxtaposed agglomerates each formed of a plurality of acicular plates, the plates of each agglomerate being generally oriented radially with respect to one another and with respect to the center of the agglomerate, the carrier of this catalyst being preferably inert; and a second step using a catalyst which could be of the same type but with a higher proportion of metals. This process is useful for the conversion of crude oils, straight run hydrocarbon residues, deasphalted oils, asphalts dissolved in aromatic distillates and coal hydrogenates.
