(54) A process for the production of low-asphaltenes hydrocarbon mixtures


(57) Deasphalted oils and distillates are produced from asphaltenes-containing hydrocarbons by two-step solvent-deasphalting (yielding a high quality DAO-1, a DAO-2 of lower quality and asphalt) and converting the DAO-2 or the asphalt by catalytic hydrotreatment into a product having a reduced RCT, which is separated by distillation into distillate fraction(s) and a residue which is subjected to thermal or catalytic cracking or which is used as feed component for solvent-deasphalting and the cracked product is separated by distillation into distillate fraction(s) and a residue which is used as feed component in solvent-deasphalting, or by subjecting the DAO-2 to thermal or catalytic cracking and/or the asphalt to thermal cracking and converting a distillation residue of the cracked product(s) by catalytic hydrotreatment into a product having a reduced RCT, which is separated by distillation into distillate fraction(s) and a residue which is used as feed component for solvent-deasphalting.
