摘要

•A micro-kinetic model for CO/C3H6/C2H6/H2 oxidation on Pt/Al2O3 is developed.•Inverse hysteresis is mainly due to formation of surface intermediates.•The possibility of steam reforming of C2H6 happening before oxidation is illustrated.•Hysteresis predicted by global and micro-kinetic models differs substantially.
