초록

This invention provides an improved process for hydroconversion of a heavy hydrocarbon oil having a CCR content of 8-30 weight percent, which process involves contacting the heavy oil in a hydrovisbreaking zone containing a low acidity zeolite catalyst and recovering and fractionating the visbroken effluent to provide distillate products and a 1000°F.+fraction which has a Kinematic Viscosity between about 30,000-60,000 centistokes at 100°F.
