Abstract
Methods are provided for performing selective hydrodesulfurization on a naphtha boiling range stream naphtha boiling range portion of a feed. It has been unexpectedly discovered that hydrodesulfurization with improved octane retention can be performed by using a catalyst that comprises CoMo supported on a catalyst support that includes a zeotype framework. By using a catalyst support including a zeotype framework, an unexpectedly high amount of octane in the naphtha boiling range portion of the hydrodesulfurized effluent is maintained.
