Isoamylene Oligomerization over Zeolite Catalysts

Grigor’eva, N. G. / Serebrennikov, D. V. / Bubennov, S. V. / Kutepov, B. I.

The study of isoamylene oligomerization over a number of microporous zeolites such as H–Y, H–MOR, H–Beta, H–ZSM-12, and H–ZSM-5 revealed that the isoamylene conversion rate decreases in the following order: H–MOR > H–Y > H–Beta-40 >> H–ZSM-12 > H–ZSM-5. The maximum yields of isoamylene oligomers were achieved by using H–MOR (85.0%), H–Y (80.1%), and H–Beta-40 (79.8%). The predominant isoamylene oligomers are dimers regardless of the zeolite catalyst used. The trimer yield reaches its highest when wide-pore zeolites like H–MOR, H–Y, or H–Beta-40 are employed. An increase in the number of acid sites enhances monomer conversion rate, oligomer yield, and oligomer molecular weight. Conditions for producing isopentene dimers and trimers with the maximum possible yield were determined.
