Abstract
A catalyst for selective hydrogenation of unsaturated diolefinic and styrenic compounds in gasolines without hydrogenating the aromatic and mono-olerinic compounds is described. It can also eliminate marcaptans when they are present in these gasolines. The catalyst comprises particulate support on which palladium is deposited, distributed at the periphery of the catalyst particles, and at least one metal selected from molybdenum and tungsten, in the form of at least one oxide.
