a residual hydrocarbon oil in the presence of hydrogen with a hydrocracking catalyst
comprising a modified zeolite Y having a unit cell size in the range of from 24.20
to 24.65 Å under operating conditions whereby at least 20% by weight of the hydrocarbons
having a boiling point of 520 °C or higher present in the residual hydrocarbon oil
is converted into hydrocarbons having a boiling point below 520 °C.
