A method for the hydrodeoxygenation of an oxygenate feedstock comprising contacting said feedstock with a sulphided catalyst composition under hydrodeoxygenation conditions, wherein said catalyst composition comprises: i) a porous carrier substantially comprised of alumina, said carrier comprising between 0 and 1 wt.% phosphorous and between 0 and 1 wt. % silicon (both calculated as oxides) and having a mean pore diameter in the range from 5 nm to 40 nm; and, ii) from 1 to 20 wt. % of an active metal component (calculated as oxides based on the weight of the composition) borne on said porous carrier and which comprises at least one Group VIB metal and at least one Group VIII metal.

La présente invention concerne un procédé d'hydrodésoxygénation d'une charge d'alimentation oxygénée comprenant la mise en contact de ladite charge d'alimentation avec une composition de catalyseur sulfuré dans des conditions d'hydrodésoxygénation, ladite composition de catalyseur comprenant : i) un support poreux constitué sensiblement d'alumine, ledit support comprenant entre 0 et 1 % en poids de phosphore et entre 0 et 1 % en poids de silicium (les deux étant calculés sous la forme d'oxydes) et ayant un diamètre moyen de pores dans la gamme de 5 nm à 40 nm ; et, ii) de 1 à 20 % en poids d'un composant métallique actif (calculé sous la forme d'oxydes sur la base du poids de la composition) déposé sur ledit support poreux et comprenant au moins un métal du groupe VIB et au moins un métal du groupe VIII.
