<p>Process for the preparation of light hydrocarbon fractions by hydrocracking of a heavy hydrocarbon oil, in which a heavy hydrocarbon oil that consists at least partly of a deasphalted oil, is hydrocracked. The hydrocracked product is separated by distillation into one or more light hydrocarbon fractions and a residual fraction. The residual fraction is divided into two portions having the same composition but differing in size and the larger portion is recirculated to the hydrocracker.</p> |
