Selective hydrogenation using palladium/platinum on crystalline silica polymorph/silicalite/high silica zeolite

摘要

Palladium or platinum is deposited on a low acidity silica polymorph/silicalite/high silica zeolites to yield a supported catalyst particularly useful in the hydrogenation of acetylenes and diolefins. The catalyst has a decreased tendency to promote polymerization which causes fouling than previously used alumina catalysts.
