Process for the preparation of light hydrocarbon distillates by hydrocracking and catalytic cracking
This patent describes a process for the preparation of a gasoline range petroleum distillate from a vacuum heavy hydrocarbon oil distillate. It comprises: passing at least a portion of the vacuum heavy hydrocarbon oil distillate to a hydrocracking zone to hydrocrack the distillate into a product stream comprising a hydrocracked distillate residue having an initial boiling point of at least 300{sup 0}C; passing the hydrocracked distillate to a distillation separation zone to separate and recover the residue; passing the residue to a catalytic cracking zone to catalytically crack the residue; passing at least a portion of the vacuum heavy oil distillate prior to hydrocracking to the catalytic cracking to catalytically crack the vacuum heaving oil distillate; withdrawing the gasoline range petroleum distillate from the catalytic cracking zone.
