    • Treating a charge obtained from a renewable source, comprises: (a) hydrotreating the charge in the presence of a fixed bed catalyst comprising hydro-dehydrogenating function and an amorphous support at 200-450[deg] C and at a pressure of 1-10 MPa; (b) separating from the obtained effluent, at least a portion of water and a hydrocarbon base; (c) eliminating nitrogen compounds from the hydrocarbon base; (d) hydroisomerizing the hydrocarbon base in the presence of selective hydroisomerization fixed bed catalyst; and (e) separating from the obtained effluent, hydrogen gas and diesel base. Process of treating a charge obtained from a renewable source, comprises: (a) hydrotreating the charge in the presence of a fixed bed catalyst at a temperature of 200-450[deg] C, at a pressure of 1-10 MPa, and an hourly space velocity of 0.1-10 per hour, and in the presence of a total quantity of hydrogen mixed with the charge at a ratio of hydrogen to charge of 50-1500 Nm 3>of hydrogen/m 3>charge, where the catalyst comprises a hydro-dehydrogenating function and an amorphous support; (b) separating from the effluent obtained from step (a), at least a portion of water and at least one hydrocarbon base; (c) eliminating nitrogen compounds from the hydrocarbon base obtained from step (b); (d) hydroisomerizing of at least a part of the hydrocarbon base obtained from step (c) in the presence of a selective hydroisomerization fixed bed catalyst comprising a hydro-dehydrogenating function and at least one mono-dimensional 10 MR zeolite molecular sieve, where the step (c) is carried out at 150-500[deg] C, at a pressure of 1-10 MPa, at a hourly space velocity of 0.1-10 per hour and in the presence of a total quantity of hydrogen mixed with the charge at a ratio of hydrogen/charge of 70-1000 Nm 3>/m 3>; and (e) separating from the effluent obtained from step (d), the hydrogen gas and at least one diesel base.
