    Abstract: The present application discloses a fluidized catalytic cracking process wherein light cycle gas oil is stripped of heavy naphtha components employing reboiled light cycle gas oil as stripping vapor. Heavy naphtha vapors stripped from the light cycle gas oil are returned to the reaction vapor as primary stripping vapor. This process results in increased naphtha octanes, and reduced sour water production from a fluidized catalytic cracking unit.

    Abstract: Separation of the catalyst-containing product effluent from a fluid catalytic cracking unit is effected in the main column by a technique which involves removing a light naphtha fraction as the single overhead stream and separately withdrawing a heavy naphtha fraction as a lower side-cut. The latter is stripped of light naphtha (for recycle to the main column) and recovered as a product stream. Preferably a portion of the heavy naphtha fraction (as withdrawn) is cooled and combined with the light naphtha overhead reflux stream.

    Abstract: HIGH QUALITY UV STABLE LUBRICATING OIL STOCKS ARE PREPARED BY SOLVENT EXTRACTING A HYDROCARBON FEEDSTOCK WITH A SOLVENT HAVING PREFERENTIAL SOLUBILITY FOR AROMATICS, THEREBY REDUCING THE AROMATIC CONTENT THEREOF AND RECOVERING A RAFFINATE PHASE THEREFROM. THE RAFFINATE IS STRIPPED OF SOLVENT AND SUBSEQUENTLY HYDROCRACKED MILD CONDITIONS TO INCREASE THE VISCOSITY INDEX OF THE RAFFINATE. THE HYDROCRACKATE PRODUCT IS THEN SOLVENT EXTRACTED WITH A SOLVENT HAVING PREFERENTIAL SOLUBILITY FOR AROMATICS, WHICH SOLVENT MAY BE THE SAME OR DIFFERENT THAN THE SOLVENT USED IN THE FIRST EXTRACTION, THEREBY FORMING A SECOND EXTRACT

    PHASE AND A SECOND RAFFINATE PHASE. THE EXTACT AND RAFFINATE PHAESE ARE SEPARATED AND THE EXTRACT PHASE STRIPPED OF SOLVENT AND RECYCLED TO THE HYDROCRACKER .

    Abstract: In fluid catalytic riser cracking of a gas oil with a zeolite catalyst the inclusion of controlled amounts of residual oil in the feed results in an improvement in octane value and/or improvement in the distribution of octane value of the gasoline product. The octane number improvement is further enhanced by hydrodesulfurizing the residual oil prior to charging to the FCC unit. However, residual oil is relatively difficult to vaporize and the extent of its vaporization will depend on the equilibrium flash vaporization temperature at the bottom or inlet of the riser. Therefore, the quantity of residual oil in the feed must be controlled in relation to the equilibrium temperature in order to, on the one hand, vaporize and crack a sufficient quantity of residual oil to obtain the octane improvement effect, while, on the other hand, keeping the quantity of residual oil which remains unvaporized below a specified level.
