Catalytic Rearrangement of Tetrahydrodicyclopentadiene to Adamantane Over Y-Zeolite

Bifunctional rare-earth exchanged Y zeolite, has the high catalytic activity for the synthesis of adamantane from tetrahydrodicyclopentadiene in the presence of hydrogen and hydrogen chloride, in a fixed bed flow system. The catalyst deactivated by pore plugging with deposited hydrocarbons can be almost completely regenerated by hydrocracking.
