Catalyst for the hydrogenation of aromatic compounds in a hydrocarbon feedstock containing sulfur

摘要

The catalysts are used in the treatment of cycle oils derived from catalytic cracking processes particularly the hydrogenation of aromatics of boiling points higher than 100 degrees C in the presence of small amounts of sulfur compounds.The catalysts have good thio-resistant properties. New thio-resistant catalysts used for the hydrogenation of unsaturated hydrocarbons in cuts containing small amounts of sulfur are claimed. These contain Pd and Pt and also at least on halogen from F and Cl on an alumina support. An Independent claim is also included for the application of the catalysts in the hydrotreatment of cycle oils.
