abstract = {The long-term stability at autothermal reforming of diesel
fuel and kerosene was studied using Juelich's autothermal
reformer ATR 9.2, which is equipped with a commercial
proprietary RhPt/Al2O3–CeO2 catalyst. The experiment was
run for 10,000 h of time on stream at constant reaction
conditions with an O2/C molar ratio of 0.47, a H2O/C molar
ratio of 1.9, and a gas hourly space velocity of 30,000
h−1. Kerosene produced via the gas-to-liquid process and
diesel fuel synthesized via the bio-to-liquid route were
used. Both fuels were almost free of mass fractions of
sulfur and aromatics. The trends for the desired main
products of autothermal reforming H2, CO, CO2, and CH4 were
almost stable when kerosene was used. When the fuel mass
flow was switched to diesel fuel however, different modes of
catalyst deactivation occurred (active sites blocked by
carbonaceous deposits, sintering processes), leading to a
decrease in the concentrations of H2 and CO2 with a
simultaneous increase in the CO content. This paper defines
carbon conversion as the decisive criterion for evaluating
the long-term stability during autothermal reforming of
kerosene and diesel fuel. Carbon conversion was diminished
via three different pathways during the long-term
experiment. Undesired byproducts found in the gas phase
leaving the reactor had the strongest impact on carbon
conversion. These byproducts included ethene, propene, and
benzene. Furthermore, a liquid oily residue was detected
floating on the condensed unconverted mass flow of water.
This happened once during the whole experiment. Finally,
undesired organic byproducts were dissolved in the mass flow
of unconverted water. These were found to be straight-chain
and branched paraffins, esters, alcohols, acids, aldehydes,
ketones, etc. Nevertheless, at the end of the long-term
experiment, carbon conversion still amounted to more than
$98.2\%.$},
