  • Fluidized catalytic cracking process for increased hydrogen production
    Patent number: 4244810
    Abstract: A fluidized catalytic cracking process for conversion of hydrocarbon charge to cracked products wherein a regenerated fluidized catalytic cracking catalyst having deposited thereon about 1000 to 10,000 ppm of nickel, vanadium, iron or mixtures thereof is treated with a sodium compound prior to use for cracking hydrocarbon charge such that hydrogen yield is increased.

  • Method of catalytic cracking of hydrocarbons
    Patent number: 3993556
    Abstract: In a fluid catalytic cracking unit utilizing a zeolite cracking catalyst and employing a multiplicity of elongated reaction zones or risers, significant improvements are obtained by introducing a light gas oil to at least one elongated reaction zone and a heavier gas oil to at least one other elongated reaction zone. Optionally, the vaporous effluent from either or both elongated reaction zones may be subjected to further cracking in the dense phase of catalyst in the reactor vessel. Operating conditions within the elongated reaction zones are established to permit the conversion of the heavier gas oil to be 0-30 volume percent lower than the light gas oil. Higher yields of higher octane gasoline are obtained where the unit is operated in the disclosed manner.
