This was a university-based research project in support of distributed reforming
production technologies for hydrogen. Our objective was to examine the steam
reforming of bio-ethanol and other related bio-derived liquids over non-precious metal
catalyst systems to enable small-scale distributed hydrogen production technologies
from renewable sources. The study targeted development of a catalytic system that
does not rely on precious metals and that can be active in the 350-550 C temperature
range, with high selectivity and high stability. To this end, we adopted a multi-prong
research strategy, that included catalyst formulation and synthesis, detailed catalyst
characterization, reaction kinetics and reaction engineering, molecular modeling and
economic analysis studies. Our approach was an iterative one, where the knowledge
gained in one aspect of the study was utilized to modify and fine-tune catalyst
development. The research addressed many fundamental and inter-related
phenomena involved in the catalytic steam reforming of ethanol that may not be readily
studied in an industrial development setting.
The outcome of the project was a catalytic system that was able to meet the DOE
targets in hydrogen production, with high H2 yield, high selectivity and stability that could
perform efficiently in the 350-550 C temperature range. In addition, we were able to
answer many fundamental questions about the catalytic systems that could easily be
translated to other catalytic systems. The study resulted in 14 refereed journal articles,
with one more in preparation. The results were also shared broadly at many different
national and international forums such as conferences of the American Chemical
Society, American Institute of Chemical Engineers, North American Catalysis Society,
International Congress on Catalysis and International Conference on Catalysis for
Renewable Sources. There were 30 presentations given at various national and
international meetings. The P.I. was also invited to give 11 lectures on the findings from
this study at many universities and research centers in the USA and other countries.
The knowledge base acquired through this study is expected to bring industry closer to
designing catalytic systems that can be tailored for the specific hydrogen production
applications, especially for distributed hydrogen production strategies.
