<p>A process is disclosed for the production of one or more atmospheric hydrocarbon oil distillates from an atmospheric hydrocarbon oil residue. The production takes place using hydrocracking as the main treatment in combination with catalytic hydrotreatment and deasphalting as supplementary treatments. The atmospheric hydrocarbon oil residue is split by vacuum distillation into a first vacuum distillate and a first vacuum residue. The vacuum residue or an asphalt obtained therefrom by deasphalting is subjected to a catalytic hydrotreatment, and the hydrotreated product is split into one or more light atmospheric distillates as end-products, a first atmospheric middle distillate as end-product or as intermediate product and an atmospheric residue that is split further by vacuum distillation into a second vacuum distillate and a second vacuum residue. The second vacuum residue or an asphalt obtained therefrom by deasphalting is at least partly again subjected to the catalytic hydrotreatment, and the vacuum distillates together with a deasphalted oil and, if desired, with the first atmospheric middle distillate are hydrocracked. The cracked product is split by atmospheric distillation into one or more light distillates as end-products, if desired a second middle distillate as end-product and a residue of which at least part is again subjected to hydrocracking. The aforementioned deasphalted oil was obtained by deasphalting either vacuum residue. The process enables economic conversion of atmospheric hydrocarbon oil residues into atmospheric hydrocarbon oil distillates, such as gasolines.</p> |
