1. A catalytic cracking process, comprising the steps of:

  • hydrotreating resid;

    thereafter deasphalting said hydrotreated resid to produce substantially deasphalted oil;

    catalytically cracking said hydrotreated oil in a catalytic cracking unit in the presence of a cracking catalyst to produce upgraded oil leaving coked catalyst; and

    regenerating said coked catalyst in the presence of a combustion-supporting gas comprising excess molecular oxygen in an amount greater than the stoichiometric amount required for substantially completely combusting the coke on said catalyst to carbon dioxide.
