PROCEDIMENTO DI IDROGENAZIONE SELETTIVA DI UNA FRAZIONE DI IDROCARBURI CONTENENTE 2 O 3 ATOMI DI CARBONIO PER MOLECOLA

摘要

A C2 or C3 hydrocarbon fraction comprising at least one mono-olefinic hydrocarbon and at least one acetylenic hydrocarbon, and optionally at least one diolefinic hydrocarbon, is hydrogenated selectively in contact with a palladium-on-alumina catalyst subjected to calcining at a relatively high temperature and whose palladium crystallites have an average size of at least 50 Angströms.
