Abstract
A H2-selective MFI zeolite membrane has been crystallized as layer on a porous ceramic tube. At 510°C, this membrane can separate H2 from iso-butane/iso-butene with mixture separation factors of 70 and H2 permeances of ca. 1 m3 (STP)/m2 hbar. In membrane supported iso-butane dehydrogenation the conversion of iso-butane was increased by almost a factor of 2. However, a detailed analysis of the experiment showed that 2/3 of the conversion increase is based on the dilution of the feed by the sweep gas and 1/3 is due to the H2 removal.
