Hydrocracking comprises denitrification and desulfurization of a first feed, high pressure and temperature distillation, hydrocracking, high pressure and temperature distillation of the hydrocracked product, post-treatment of vapor from the distillation unit, and passing of a second feed having a lower boiling point than the first feed to a high pressure and temperature distillation unit for rapid cooling. - Hydrocracking comprises feeding hydrocarbon and hydrogen to a denitrification and desulfurization zone, passing the resulting stream to a high pressure and temperature distillation unit utilizing a hot hydrogen-rich distillation gas to produce a hydrocarbonated liquid, passing the liquid to a hydrocracking zone, distilling the resulting stream using high pressure and temperature distillation unit, passing the vapor from the distillation unit to a post treatment hydrogenated reaction zone for saturating contained aromatic compounds, and passing a second feed having a lower boiling point than the first feed to high pressure and temperature distillation unit for rapid cooling.
