DESCRIPTION:Zeolite Membrane Reactors and Thin Film Sensors for Advanced Fossil and Biomass based Energy Systems  Abstract:  Zeolites are crystalline aluminosilicate materials with ordered pores of nanometer or sub-Nanometer scale sizes. Traditionally, zeolites are used as highly efficient adsorbents and shape-selective catalysts in chemical and energy industries. In the past two decades, various types of zeolite membranes and thin films have been successfully synthesized for a wide range of applications in molecular separations, electrochemical and optical chemical sensors, and special surface coatings/furnishings.  This presentation discusses our recent work on zeolite membranes for high temperature water gas shift (WGS) reaction which is a key operation in pre-combustion CO2 capture or hydrogen production from fossil and biomass stocks. Our study on the WGS membrane reaction indicates that, under high temperature and pressure, zeolite membranes with only moderate H2/CO2 selectivity are capable of achieving nearly complete CO conversion (>99.8%) in a single reactor with some compromise in the ability of simultaneous H2 or CO2 purification. The presentation also reports the utilization of zeolite thin films as probing materials for novel fiber optic chemical sensors (FOCS) and as effective protective layers for high temperature optical gas sensors to operate in-situ in harsh conditions involved in fossil and biomass based power plants. | Event post: https://che.uic.edu/events?page_id=1229
