A process for reducing sulfur, nitrogen, metals and asphaltene contents, while increasing the yield of distillable fractions in heavy hydrocarbons, by using a cooled light fraction as a liquid quench stream. The light fraction is obtained by splitting heavy hydrocarbons into a heavy fraction, and a light fraction which may be injected at spaced locations along a system of fixed-bed reactors series that comprises a first hydrodemetallization (HDM)/hydrodeasphaltenization (HDAs) step, followed by a second hydrodesulfurization (HDS)/hydrodenitrogenation (HDN)/hydrocracking step. The metal and asphaltene rich heavy fraction have contact with the entire catalyst system, while the light fraction is injected as side feed and quench stream(s) into the second reactor, where it is treated in admixture with the heavy fraction for elimination of the impurities of the light fraction.
