Oligomerization and isomerization of dicyclopentadiene over mesoporous materials produced from zeolite beta

• A highly ordered mesoporous aluminosolicate was synthesized using zeolite beta.
• MMZ-Hβ has well-developed mesopore.
• Weak acid sites, mainly Lewis acid sites, were formed over MMZ-Hβ.
• MMZ-Hβ was applied to a DCPD oligomerization/DCPD oligomer isomerization.
• MMZ-Hβ catalyst shows high reaction activity and selectivity.

Mesoporous materials synthesized from commercial zeolite beta were applied to a dicyclopentadiene oligomerization/dicyclopentadiene oligomer isomerization reaction. A highly ordered mesoporous aluminosolicate, MMZ-Hβ was synthesized using commercially available zeolite beta as its framework source. It was confirmed that MMZ-Hβ has smaller surface area and pore volume than zeolite beta but mesopores were well developed. Though the amount and the strength of acid sites over MMZ-Hβ decreased compared with zeolite beta, the MMZ-Hβ catalyst shows high reaction activity and selectivity in a dicyclopentadiene oligomerization/dicyclopentadiene oligomer isomerization reaction, which can be attributed to the large pore size of MMZ-Hβ which is favorable for the diffusion of reactant, intermediate, and product.
