    Abstract: The present invention relates to a process for preparing a diesel hydrocarbon fraction, comprising the following steps: (a) reacting at least a renewable feedstock comprising glycerides with water at a temperature within the range of 150–400°C and a pressure within the range of 1-20 MPa, forming at least one mixture of fatty acids and glycerine; (b) separating said glycerine from said mixture of fatty acids; (c) subjecting said mixture of fatty acids to catalytic hydrotreatment in the presence of hydrogen, obtaining a reaction product comprising: (i) at least one gaseous effluent comprising hydrogen, water vapour and CO
    2 and possibly CO, (ii) at least one diesel hydrocarbon fraction comprising branched paraffins in a prevalent quantity with respect to the linear paraffins, said catalytic hydrotreatment being carried out in the presence of a catalytic composition comprising at least one metal of group VIIIB dispersed on at least one acid carrier for catalyzing a hydroisomerization reaction of linear paraffins to branched paraffins; (d) separating said diesel hydrocarbon fraction from said reaction product.
