Abstract
A two-step process for the production of large quantities of heartcut distillate resin precursors from steamed cracked gas oil product which involves hydrogenation of the steam cracked gas oil followed by steam cracking of the hydrogenated product to produce a greater than 15 wt. % yield of heartcut distillate resin precursors. A process for producing heartcut distillate comprising hydrogenating a hydrocarbon oil comprising two-ring aromatic molecules to form a hydrogenated hydrocarbon oil comprising partially saturated naphtheno-aromatic molecules; and subjecting a feedstock comprising hydrogenated hydrocarbon oil to steam cracking under conditions which favor producing a heartcut distillate containing an amount greater than about 4 wt. % yield of heartcut distillate resin precursors. A method for producing heartcut distillate which involves subjecting a hydrogenated hydrocarbon feedstock boiling in the range of about 200.degree. C. to 320.degree. C. to steam cracking under conditions which favor producing a heartcut distillate containing an amount greater than about 4 wt. % yield of heartcut distillate (HCD) resin precursors. A method for producing heartcut distillate which invol…
