Research Description

My research group is engaged in research in new membranes and materials for separations and fuel cells including those briefed below.  

New Membranes for Hydrogen Purification and Carbon Capture 

We are developing new membranes and membrane processes for energy, environmental and biochemical applications, including a novel CO2-selective membrane process in conjunction with water-gas-shift (WGS) reaction for the purification of H2 for fuel cells.  The new process is based on the facilitated transport mechanism, in which CO2 transport through the membrane is enhanced with reaction in the membrane, and H2 is rejected by the membrane due to absence of reaction 

This work involves the synthesis, characterization, and modeling of new CO2-selective membranes that would achieve the purification process.  The membranes synthesized comprise primary, secondary and tertiary amines in polymer networks.  We have identified membranes with high CO2 permeability and CO2 / H2 selectivity at 50 – 180oC.  As expected, the permeability has increased as temperature increases.  However, the selectivity has also increased as temperature increases; this is impossible for a membrane based on the solution-diffusion mechanism.  The selectivity increase is due to the facilitated transport with a higher CO2-amine reaction rate and lower H2 solubility in the membrane as temperature increases.    

We have developed a non-isothermal model for the countercurrent WGS membrane reactor and elucidated the effects of system parameters on the reactor for synthesis gases from steam and autothermal reforming.  The modeling results have shown that H2 enhancement via CO2 removal and CO reduction to <10 ppm are achievable.  Our recent experiments have verified these results.  The scale-up of the CO2-selective membrane for hydrogen purification for fuel cells is in progress.  The investigation of the membranes for other applications, including CO2 capture for sequestration, H2S from syngas, CO2 and H2S from biogas, and CO2 from flue gas and confined space air, is underway.  Recently, we have achieved clean-up of H2S to <10 ppb in a syngas.  

New Proton-Exchange Membranes   

We have synthesized new proton-exchange membranes (PEMs) from copolymers containing sulfonated polybenzimidazole and polyimide hard segments for proton conductivity as well as hydrophilic soft segments for water retention.  The PEMs have shown high conductivity at 25 – 120oC.  The new membranes can enable the widespread application of PEM fuel cells. 

Water Purification

We have studied a new concept of incorporating hydrophilic groups chemically into membrane structure to provide an additional pathway for water transport and to overcome the low hydrophilicity/flux issue inherent in interfacially polymerized aromatic polyamide membranes.  This work has resulted in >100% increase in water flux vs. the industry standard Film-Tec FT-30 membrane while maintaining a high NaCl rejection of >99%.  In addition, recent advances on supported liquid membranes (SLMs) with strip dispersion have been for the removal and recovery of (1) heavy metals, including chromium, copper, zinc, and strontium and (2) organic compounds from wastewaters.  

Nanoporous Membranes for Bioengineering

Extending nanoporous membranes, including SLMs with strip dispersion, for bioengineering is in progress.  This includes the recovery of products from fermentation broths and the controlled release of drugs.  The research involves the synthesis and characterization of new nanoporous membranes with controlled morphology and new extractants with high specificity towards the target species, e.g., Cephalexin and Interferon α.  The characterization includes (1) transport enhancement and mechanisms and (2) reaction kinetics and stoichiometry at membrane interfaces.
