ABSTRACT:
We provide reverse-graded catalyst systems which are capable of removing metals and sulfur from a hydrocarbon feedstock. They comprise two or more catalyst layers in which at least two successive catalyst layers characterized as having decreasing desulfurization activity, and increasing average macropore diameter in the direction of hydrocarbon flow. We also disclose a process for using them.
