Abstract

The selectivity and turnover frequency for isobutene production was shown to increase with the Si/Al ratio of fresh HFER. This can be explained by considering the zeolite pore system as a series of non-interconnected nanoreactors (the 10-MR channels) in which the molecules diffuse and react bimolecularly without any possibility of desorption before the exit.
