Process for the conversion of a heavy asphaltenes-containing hydrocarbonaceous feedstock comprising at least 25 %wt of hydrocarbons with a boiling point of at least 520 DEG C into products with a lower boiling point, which process comprises preheating the hydrocarbonaceous feedstock, passing the preheated feedstock through a thermal cracking zone so that a conversion of the hydrocarbons with a boiling point of 520 DEG C and above of at least 35 %wt is obtained, separating the effluent from the cracking zone into one or more distillate fractions and a residual fraction, and deasphalting the residual fraction to obtain an asphalt and a deasphalted oil.
