摘要：
The hydrotreating of petroleum feedstock is improved by using a layered transition metal catalyst, a mixture of such catalysts or a stacked bed of transition metal catalysts that has a selected ratio of edge to rim sites sufficient to provide a product having a predetermined sulfur and nitrogen content.
In another aspect of the present invention, there is provided a method for selecting a transition metal catalyst system for use in hydrotreating nitrogen and sulfur containing feedstocks to provide a hydrotreated product having a predetermined nitrogen and sulfur content and at a predetermined reaction residence time, which method comprises: selecting the amount of sulfur and nitrogen to be removed from a given feedstock by hydrotreating to obtain a product having a predetermined nitrogen and sulfur content; determining the variation in the reaction kinetics for sulfur and nitrogen removal of the given feedstock by hydrotreating with a transition metal catalyst of varying edge to rim ratios; selecting, for a predetermined reaction residence time, that ratio from the varying edge to rim ratios of the transition metal catalyst that provides the requisite sulfur and nitrogen removal to provide the product of predetermined sulfur and nitrogen content.
