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 C-asphaltenes.
