Presentation Title

 Advances in Hydrogen Separation using Palladium-Based Membranes

Abstract

 

Global climate change and fossil fuel depletion have driven the need to shift energy use from the conventional carbon cycle to the hydrogen cycle. One of the prime advantages of consuming hydrogen as a fuel is zero emissions of carbon dioxide and other pollutants. Hydrogen can be produced from fossil fuels, biomass, and hydrocarbons. However, in most conversion processes, hydrogen-rich gases rather than pure hydrogen are produced. There are several ways to separate and purify hydrogen from hydrogen-rich gases such as pressure swing adsorption, cryogenic distillation, and membrane separation. When hydrogen is separated from hydrogen-rich gases using membranes, palladium (Pd) has demonstrated its excellent features of high hydrogen permeability and selectivity. In addition to hydrogen separation and purification, Pd-based membranes can also be thought of as a potential tool to fulfill CO2 capture. In this talk, the advances in hydrogen separation and purification based on Pd-based membrane systems will be introduced. The important phenomena such as hydrogen permeation, concentration polarization, and membrane permeance measurement will be illustrated. The interfacial and bulk mass transfer behaviors of hydrogen in Pd-based membrane systems will be underlined. The presentation will also show hydrogen permeation in Pd membrane tube systems approached by computational fluid dynamics (CFD) along with artificial intelligence or evolutionary computation, demonstrating the potential of simulations as a powerful tool to aid in membrane system design.
