1. A catalyst, composition comprising:
- an activated carbon catalyst support material;
a first metal selected from the group consisting of chromium, molybdenum and tungsten, wherein the first metal is present in the oxide form of the metal in an amount of between about 15 and 30% by weight of the support material; and
a second metal selected from the group consisting of iron, ruthenium, osmium, cobalt, rhenium, iridium, nickel, palladium and platinum, wherein the second metal is present In the oxide form of the metal in an amount of between about 1 and 10% by weight of the support material.

Abstract
This invention relates to a hydrodesulfurization catalyst, a method for preparing the catalyst, and a method for the preparation of low sulfur gasoline fuel with minimal loss of RON. The catalyst particles include a group VIB metal and a support material having relatively high surface area, and optionally includes one or more group VIIIB metal. The method for preparing the catalyst allows for greater loading of the active metal species on the surface of the support material under aqueous reaction conditions.
