Angelo BASILE, degree cum laude in Chemical Engineering and a Ph.D. in Technical Physics, is a Senior Researcher at the Institute Membrane Technology (ITM) of the Italian National Research Council (CNR). At ITM-CNR, he is responsible of the research related to both the ultra-pure hydrogen production and CO2 capture using Pd-based Membrane Reactors. Angelo Basile’s h-index is 42, with 256 document results, cited by 2227 documents and 4405 total citations in the subject area: Energy, Chemical Engineering, Materials Science, Chemistry,  Environmental Science, Engineering (  –  Nov. 30, 2017). He was the Director of the ITM-CNR during the period Dec. 2008 – May 2009. Since 2014 Basile has been Full Professor of Chemical Engineering Processes.


Nowadays, the main industrial process for hydrogen production is the natural gas reforming, consisting of a multi-stages process in which methane steam reforming takes place in harsh conditions (800-1000 °C and 15-20 bar), followed by two water gas shift reactors and other separation/purification steps for generating high purity hydrogen. However, the natural gas composition can vary widely from source to source, although often containing  traces of H2S. This represents a critical issue, being responsible of the damage on the permeation characteristics of the Pd-based membranes and, consequently, affecting the overall performance of the membrane reactor. In the last decade, many researchers studied the preparation of composite membrane based on Pd, alloyed with other metals able to offer higher resistance to sulfur contamination. In this work, a wide panorama about composite Pd-based membranes is reviewed, particularly pointing out the preparation and characterization of the composite Pd-alloyed membranes. As a case study, a Pd-Au membrane reactor is used to carry out steam methane reforming reaction, by comparing the experimental results with an equivalent conventional reactor. 

Audience Take Away:

•    Explain how the audience will be able to use what they learn?
The audience will enjoy an alternative technology presentation (Pd-based membrane and membrane reactor technology) for producing high grade hydrogen. 
•    How will this help the audience in their job? Is this research that other faculty could use to expand their research or teaching? Does this provide a practical solution to a problem that could simplify or make a designer’s job more efficient? Will it improve the accuracy of a design, or provide new information to assist in a design problem? List all other benefits. 
1)    The presentation will offer a new panorama for hydrogen production from reforming reactions using alternative systems such as inorganic membrane reactors. 
2)    Furthermore, this technology will offer to the audience the possibility of appreciating the new approach for the process simplification related to the membrane technology application, useful in the viewpoint of Process Intensification Strategy for reducing the number of conventional process stages for producing and purifying hydrogen from reforming reactions of derived of fossil fuels or renewable sources.
