A process for converting a biomass material comprising a) converting a biomass material in one or more steps into one or more C3-C12 oxygenates; b) contacting the one or more C3-C12 oxygenates with hydrogen at a hydrogen partial pressure of more than 1.0 MegaPascal in the presence of a sulphided carbon-carbon coupling catalyst; wherein the carbon-carbon coupling catalyst comprises equal to or more than 60 wt % of a zeolite and in the range from equal to or more than 0.1% wt to equal to or less than 10 wt % of a hydrogenation metal, based on the total weight of the carbon-carbon coupling catalyst.
