Abstract: The invention relates to a method for optimizing layered catalytic processes. This is accomplished by testing various catalysts with a compound found in a feedstock to be tested, to determine the facility of the catalyst in hydrogenating, hydrosulfurizing, or hydrodenitrogenating the molecule, and hence the feedstock. In a preferred embodiment, the Double Bond Equivalence of the feedstock and molecule are determined, and catalysts are pre-selected based upon their known ability to work with materials of this DBE value. In preferred embodiments, the layered catalysts include a demetallization catalyst, used before hydrocracking. In additional preferred embodiments, the test feedstock contains 500 ppmw or less asphaltenes, preferably C5-asphaltenes.

Abstract: A process is described for reducing the total acid number of a refinery feedstock. A refinery feedstock containing naphthenic acids is contacted with an effective amount of solid catalyst that has been pretreated with an aqueous caustic base, for a period of time sufficient to neutralize at least a portion of the naphthenic acids in the feedstock. Thereafter, the aqueous phase is separated from the neutralized refinery feedstock.

Abstract: A process is described for reducing the total acid number of a refinery feedstock. In one embodiment, refinery feedstock containing naphthenic acids is contacted with an effective amount of solid catalyst in the presence of an aqueous caustic base, wherein the caustic base is sodium hydroxide or potassium hydroxide, for a period of time sufficient to neutralize at least a portion of the naphthenic acids in the feedstock. Thereafter, the aqueous phase is separated from the neutralized refinery feedstock. In another embodiment catalyst is pretreated with a caustic base solution and contacted with refinery feedstock to reducing the total acid number.

Abstract: A hydrocarbon feedstock is hydrocracked in a hydrocracking zone and the effluent is fractioned to recover a light fraction, a middle fraction containing aromatic compounds and a heavy fraction. The heavy fraction is recycled to the hydrocracking zone for further hydrocracking. The middle fraction is introduced to an aromatic separation zone. A product stream is recovered from the aromatic separation zone comprising a middle fraction having a reduced content of aromatic compounds as compared to the middle fraction recovered from the fractionator. Aromatics from the aromatic separation zone are recycled to the hydrocracking zone for further hydrogenation and cracking.
