Özet
Kinetics of autothermal reforming (ATR) of propane on bimetallic Pt-Ni catalyst supported over δ-Al2O3 is investigated at 673 K with the purpose of obtaining an easy-to-implement power-law type rate equation. The rate expression is proposed for conditions extending up to 20% propane conversion and has reaction orders of 1.64, 2.44 and -0.59 in propane, oxygen and steam partial pressures, respectively. Parameters estimated by non-linear regression analysis in the MATLAB™ environment can be reliably used for propane ATR in the steam-to-carbon ratio range of 2.0e3.0 and carbon-to-oxygen ratio range of 3.0e5.4. The apparent activation energy is calculated as 46 ± 4 kJ mol-1 in the 653-693 K interval. Copyright © 2012, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd. All rights reserved.
