The present invention relates to a process for the hydrotreatment of a vegetal biomass. Specifically, the present invention relates to a process for the hydrotreatment of a vegetal biomass comprising: a) subjecting said vegetal biomass to a hydrotreatment in a first reactor, said hydrotreatment comprises contacting said vegetal biomass in an aqueous medium and a metal oxide, a mixed metal oxide, or a metal- metalloid oxide catalyst comprising at least 35% by weight of metal oxide, mixed metal oxide, or metal-metalloid oxide relative to the total weight of the catalyst, with hydrogen at a pressure in the range of 10 to 400 bar and at a temperature in the range of 50 °C to 300 °C until a predetermined level of the hydrotreatment of said biomass is obtained and wherein the metal oxide, a mixed metal oxide, or a metal-metalloid oxide catalyst comprises nickel. Further, the present invention relates to a metal oxide, mixed metal oxide or metal-metalloid oxide catalyst. Furthermore, the present invention relates to the use of the catalyst.
