n-Pentane aromatization over chemical vapour deposited MFI zeolite enhanced para-xylene content in xylenes as high as 99%. With increase in reaction temperature from 500 to 540 degrees C para-xylene selectivity changed only from 99 to 93%. The aromatization over silylated MFI zeolite shows very good potential for developing a new process for converting low value C-2-C-5 hydrocarbon streams to industrially important benzene, toluene and para-xylene.
