Abstract
Cyclohexene was reacted at 523 °K over Y-zeolite catalysts with a unit cell constant in the range of 2423 to 2448 pm. The selectivity toward the hydrogen transfer products (cyclohexane plus methylcyclopentane) increases with the unit cell constant, while the selectivity toward isomerization products (methylcyclopentene plus methylcyclopentane) remains constant in the unit cell constant range of 2448 to 2427 pm and increases as the unit cell constant decreases to 2423 pm. The results are rationalized on the basis of acid site density and the nature of the reactions. Hydrogen transfer, being a bimolecular reaction, is favored by a high-acid site density, while isomerization of olefins, being a unimolecular reaction, is not dependent on site density but only on strength of the acid site. Thus, reaction of Cyclohexene can be used as a test reaction to measure hydrogen transfer properties of acid catalysts. The relevance of these results to product quality from catalytic cracking is discussed.
