METHOD FOR OPTIMIZING CATALYST LOADING FOR HYDROCRACKING PROCESS

摘要

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.

1. A method for optimizing a layered hydrocracking catalytic process, comprising (i) contacting a model compound capable of (a) being hydrocracked as well as at least one of (ii) hydrogenation, hydrosulfurization and hydrodenitrogenation to a plurality of catalysts to determine an optimal catalyst for each of (i) and (ii), (b) followed by layering the optimal catalysts for each of (i) and (ii) in a reaction chamber based on their activity reacting with said model compound, and (c) contacting a feedstock to the layered catalysts under condition favoring formation of lower weight hydrocarbon from said hydrocarbon containing feedstock, wherein said model compound boils in the range of 180° C.-520° C. and is selected from the group consisting of methylnaphthalene, dibenzothiophene, an alkylated or naphthalated derivative thereof, a basic nitrogen compound and a carbazole molecule.
