摘要：

Hydrotreating of distillate fractions of Timahdit Moroccan shale oils was studied by a batch method at 340-degrees-C and 70 bar hydrogen pressure over a conventional sulphided NiO-MoO3/gamma-Al2O3 catalyst. The removal of heteroatoms is easier for the light fractions containing paraffins than for the heavier ones containing aromatics. These results were obtained by direct hydrotreating of distillates resulting from the distillation of the crude oil and by hydrotreating of the most representative fractions (paraffins, aromatics) obtained after deasphalting and chromatography operations of the preceding distillates. The Timahdit pyrolysis oil consists of about 50% liquids where removal of heteroatoms is relatively easy. Upgrading of this oil is thus interesting for Morocco to meet the local demand for light hydrocarbons.
