摘要 <p>Treating petroleum charges to form a gas oil cut with a sulfur content of = 50 ppm, comprises mild hydrocracking in a fixed catalyst bed in the presence of hydrogen, separation of a gas containing hydrogen and hydrogen sulfide formed during hydrocracking and a fraction heavier than gas oil, hydrotreatment by contacting at least a portion of that distillate cut comprising the gas oil fraction, a mixture with a charge obtained from crude or refined renewable source, with a catalyst in the presence of hydrogen and separation of hydrogen gas and diesel cut. Treating petroleum charges containing >= 80 wt.% of components with a boiling point of greater than 340[deg] C and >= 0.05 wt.% of sulfur, to form a gas oil cut with a sulfur content of = 50 ppm, comprises mild hydrocracking in a fixed bed of catalyst at 300-500[deg] C, at a pressure of 2-10 MPa, and a hourly space velocity of 0.1-10 per hour and in the presence of 100-5000 Nm 3> of hydrogen per m 3> of charge, the net conversion into products boiling below 360[deg] C being 10-50 wt.%, separation of a gas containing hydrogen and hydrogen sulfide formed during the mild hydrocracking from the effluent from a distillate cut containing diesel and a fraction heavier than gas oil, hydrotreatment, by contacting at least a portion of that distillate cut comprising the gas oil fraction, a mixture with a charge obtained from crude or refined renewable source, with a catalyst, at 180-320[deg] C, at a pressure of 2-10 MPa, with a hourly space velocity of 0.1-10 per hour in the presence of 200-5000 Nm 3> of hydrogen per m 3> of charge and separation of hydrogen gas and diesel cut.</p>
