Because butene-1 is used as a monomer for the production of linear low density polyethylene (LLDPE) and polybutene, the worldwide demand of butene-1 is gradually increasing. It is necessary to produce butene-1 selectively in butene-2 isomerization because the byproducts such as iso-butene, octenes, and propylene can be produced through skeletal isomerization, oligomerization, and cracking, respectively. To increase the selectivity to butene-1 in butene-2 isomerization, mesoporous silicates were adapted as catalysts. The yield of butene-1 over MCM-41, Al-MCM-41, and MCM-48 was higher than that over alumina-based catalysts. The activity and selectivity over mesoporous silicates in butene-2 hydrogenation correlated with the acidity of the catalysts through ammonia-temperature programmed desorption and pyridine FTIR. This is an abstract of a paper presented at the AIChE Annual Meeting (San Francisco, CA 11/12-17/2006).
