The influence of acidities of boron- and aluminium-containing MFI zeolites on co-reaction of methanol and ethene

Author affiliations

Abstract

A series of boron- and aluminium-containing MFI zeolites were synthesized and various characterization techniques, such as NMR (27Al, 29Si and 11B), were employed to study the acidities of zeolites. Moreover, in situIR was applied to investigate the interaction of methanol and ethene with the acid sites, and those catalytic materials were used for co-reaction of methanol and ethene to produce propene. The production of propene was related to the Al content of the zeolites with Si/Al ratios of higher than 90. It is implied that the presence of boron during the synthesis directed the aluminium to occupy certain tetrahedral sites in the zeolite framework, thus preventing the formation of ethene oligomers, and resulting in increased propene selectivity.
