Presentation Title

Operation and System Optimization for Hydrogen Production and Separation

Abstract Over the last several decades, hydrogen has been considered as a promising green fuel to substitute fossil fuels for heat and power generation. In recent years, the development of hydrogen technology and economy has attracted a great deal of attention because it is a promising route to achieve deep decarbonization of the global energy system. Hydrogen is a non-carbon fuel; therefore, no air pollutants are emitted when hydrogen is burned. Meanwhile, hydrogen is a potential energy carrier, so it can be delivered to the appropriate places for its usage. In recent years, significant progress in proton exchange membrane fuel cell (PEMFC) has been made. Accordingly, hydrogen can be applied in the transportation sector through the applications of PEMFC. On account of a foreseeable hydrogen-based society in the future, hydrogen production and separation with high-efficiency routes become a crucial task in the implementation of hydrogen technology. In this study, a number of operation and system optimization methods for hydrogen production from thermochemical methods (such as gasification, catalytic partial oxidation, and autothermal reforming) and for hydrogen separation using palladium membranes will be illustrated. The introduced optimization methods include the Taguchi method, response surface method (RSM), and Nelder-Mead method. From these methods, the influences of operating conditions (e.g., temperature, steam-to-carbon ratio, oxygen-to-carbon ratio, and GHSV) on hydrogen yield and recovery can be figured out. The performances of the optimization methods will also be addressed.
