Process for Reacting an Aromatic Hydrocarbon in the Presence of Hydrogen

A process comprising:

• providing a starting material comprising one or more aromatic hydrocarbons, and having an aromatic sulfur compound content and a total sulfur content;
• reducing the aromatic sulfur compound content and the total sulfur content in the starting material;
• and
• hydrogenating the one or more aromatic hydrocarbons in the presence of a supported ruthenium catalyst and hydrogen.

A process comprising:

• providing a starting material comprising one or more aromatic hydrocarbons, and having an aromatic sulfur compound content and a total sulfur content;
• reducing the aromatic sulfur compound content and the total sulfur content in the starting material;
• wherein reducing the aromatic sulfur compound content and the total sulfur content in the starting material is carried out in the presence of a desulfurizing agent comprising 35 to 45% by weight of copper oxide, 35 to 45% by weight of zinc oxide, and 10 to 30% by weight of aluminum oxide;
• and wherein the aromatic sulfur compound content is reduced to ≦70 ppb, and wherein the total sulfur content is reduced to ≦200 ppb.
