- Abstract
- Oligomerization of isobutene has been investigated over AlCl3-loaded USY zeolite catalysts in order to produce triisobutenes or remove/separate isobutene from C-4 streams. Stable isobutene conversion and high selectivity for trimers and tetramers were attained over the modified zeolite with high ratio of Lewis acid site-to-Bronsted acid site, suggesting that a potential trimerization catalyst can be obtained easily by loading a Lewis acid into an acidic zeolite catalyst. This catalyst can be facially produced by physical mixing and can be easily restored its activity after deactivation by simple calcinations.
