A Prospective of Coal Fly Ash Conversion to Mfi Membrane for High Grade Biofuels Purification

Abstract

MFI is a structure of aluminosilicate zeolite mineral belonging to the pentasil family of zeolites. The current paper focuses on preparation of MFI zeolite from coal fly ash by hydrothermal process. Coal fly ash was utilized as the sources of silica. The as-synthesized zeolite was characterized by X-ray diffraction (XRD) to identify the structure and microstructure morphology observation by Scanning Electron Microscope (SEM) and adsorption-desorption analysis using nitrogen at 77 K. This kind of zeolite has a highly prospective to increase the purity of ethanol from technical grade become the fuel grade, catalyst, molecular sieve and adsorbent to reduce the emission gas.
