Abstract
The development of efficient reformers for the on-board- production
of hydrogen from liquid hydrocarbon fuels like gasoline is one of
the challenges for the implementation of fuel cell propulsion systems
for automobiles. It requires detailed kinetic information about the
reforming reactions of the main gasoline components. Such information
is presently only scarcely available, mainly because of the unusual
high temperature and short contact time reaction conditions. Therefore,
a novel isothermal reactor for kinetic measurement of heterogeneous
catalytic reforming reactions under actual operation conditions (T
= 800degreesC, p = 5 bar) has been developed. Different hydrocarbon
fuels (iso-octane, hexene, toluene, gasoline) were studied under
steam reforming (SR) and autothermal reforming (ATR) conditions using
a proprietary noble metal catalyst supported on metallic monolith
structures. On the basis of these results different reaction pathways
for SR and ATR are discussed. The results obtained will be used for
design and optimization of mobile autothermal reformers. (C) 2002
