Synthesis of zeolite-Zeolite (MFI-FAU) composite catalysts for the isomerization of n-Hexane

In this research work,the aim is to produce a relatively novel zeolite-zeolite (mfi-fau) composite catalyst having better potential of catalyzing isomerization of lighter hydrocarbons such as light naphtha,n-pentane,n-hexane,n-heptane and mixture thereof. a series of zeolite-zeolite (mfi-fau) composite catalysts have been synthesized by incorporating previous practices and techniques. the catalytic performance of as-synthesized zeolite-zeolite (mfi-fau) composite catalysts have been investigated by isomerizing 95% pure n-hexane in conventional fixed bed flow micro-reactor at temperature 200-240 ºc under atmospheric pressure. in order to explore chemical and physical features of zeolite-zeolite (mfi-fau) composite catalysts,they are examined and characterized using powder x-ray diffraction (xrd),scanning electron microscopy (sem) coupled with energy-dispersive x-ray spectrometry (edx),n2 adsorption-desorption measurements (bet,bjh,t-plot measurements) and fourier transform infrared (ftir) spectroscopy equipped with attenuated total reflectance (atr) arrangements. © 2017 chemical society of pakistan. all rights reserved.
