PhD Dissertation:Â â??Syngas Production via Water and Carbon Dioxide Thermolysis on Mixed Ionic-Electronic Conductive Membranes.â?
Under supervision of Professor Ahmed F. Ghoniem, Ronald C. Crane (1972) Professor; Director, Center for Energy and Propulsion Research; Director, Reacting Gas Dynamics Laboratory, Massachusetts Institute of Technology
Inorganic membrane reactor finds numerous industrial and scientific applications such as hydrogen production, hydrocarbon processing, CO2 splitting and kinetic studies.Â By using a semi-permeable membrane, reactants can be doped or products can be separated. Therefore, the thermodynamic limit can be overcome and the selectivity can be enhanced. For example, a mixed ionic-electronic conductive membrane facilitates H2O/CO2 splitting at elevated temperatures and increases the selectivity to syngas in partial oxidation of methane. The implementation of such an oxygen permeable membrane also reveals the kinetics of partial oxidation of methane. Experimental and numerical studies are used to understand the reaction kinetics and limiting steps and to optimize the reactor design. Ab initio studies can reveal the fundamentals of charged species transport and transition states in reactions. These information can all lead to the optimization of reactor in industrial scale.
My ultimate goal for all my potential researches is to utilize the fundamental understanding in science to guide and optimize the operation in engineering. Therefore, in the future, I foresee myself collaborating closely with scientists and industrial partners to make the findings in my own laboratory into reality.

I have been working on several fields on chemical engineering: heat/mass transfer, electrochemical reaction/diffusion, reactor analysis and chemical kinetics. My previous work in Zhejiang University was focused on experimental studies on different types of heat transfer enhancement techniques: fin tubes for falling film evaporation and nanofluids for supercritical heat transfer. Both projects were based on industry applications. Now I am working on an interdisciplinary research as my PhD thesis, which involves chemical kinetics (surface reaction) and electrochemical diffusion (ion transport membrane). Tools in various physical scales are used in my thesis:Â femto (Density Functional Theory), nano (Microscopy Characterization), macro (System Scale Thermodynamics).Â This means both experiments and simulations are used to understand the chemical process. Additionally, my work experience in Wolverine Tube, INC and Robert Bosch LLC granted me the insights in researches in industry, which will benefit my collaboration with industrial partners.
At MIT, I took a graduate course â??Instruction in Teaching EngineeringÂ â?? and applied the knowledge on teaching when I TAâ??ed two courses at MIT: Fundamental of Advanced Energy Conversion (both undergrad and grad) and Introduction to Heat Transfer (undergrad). I got evaluation from students with 6.5/7 and 6.6/7 for these two course, respectively. Besides, I have mentored three undergraduates at MIT under my thesis work: one from MIT-Egypt Exchange Fellowship Program (3 months) and two from MIT Undergraduate Research Opportunities Program (UROP) (5 and 8 months).
