Abstract
An improved hydrocracking process of hydrocarbon charges, in two stages with an intermediate separation, in which the second-stage of hydrocracking is carried out in the presence of an added nitrogen content which is greater than 150 ppm by weight, preferably about 500 ppm by weight, and preferably in the presence of a Y zeolite catalyst, produces high yields of middle distillate.
