INTRODUCTION
The conversion of logistics fuels (JP-5, JP-8, Jet-A and diesel) to hydrogen
through steam reforming poses a challenge since these fuels contain sulfur
up to about 1000 ppm leading to catalyst deactivation due to sulfur
poisoning. Thus, the development of sulfur-tolerant catalysts for logistic
fuels becomes critical. In this presentation, we would highlight our recent
efforts to develop novel catalyst formulations that offer high activity,
selectivity, and enhanced sulfur tolerance. The successful development
consists of three systematic considerations: (i) formulating nominally doped
nanoscale ceria-supported precious metal catalyst matrices, (ii) designing of
an agile sulfur-binding component, and (iii) fabricating a compact reformer
design based on thin corrugated stainless steel foil.
MATERIALS AND EXPERIMENTAL
Systematic structural and microstructural characterization of nanoscale
ceria-based catalysts and nanoporous sorbent formulations were carried out
