Journal ArticleDOI
Deactivation of a Pt/Al2O3 catalyst during the oxidation of hexafluoropropylene
TL;DR: A 5% Pt/Al 2 O 3 catalyst was exposed to hexafluoropropylene (HFP) at concentrations between 500 and 4,500 ppm in humid air at temperatures between 300 and 400°C as discussed by the authors.

A new strategy for improving the warm-up performance of a light-off auto-catalyst for reducing cold-start emissions:
S-J Jeong,W-S Kim +1 more
TL;DR: In this paper, a double-substrate type of light-off catalysts was proposed to maximize the cold-start performance of the LOCs by considering not only the three-dimensional fluid flow but also the heat and mass transfer with chemical reactions.
Journal ArticleDOI
Modeling of two-step CO oxidation light-off on Pt/γ-Al2O3 in the presence of C3H6 and NOx
TL;DR: In this paper, a global reaction kinetic model is proposed that captures all the experimentally observed phenomena including transient accumulation of the reaction intermediates on the catalyst surface and the resulting impact on CO and C3H6 conversion.
Journal ArticleDOI
A Simplified Three-Way Catalyst Model for Transient Hot-Mode Driving Cycles
TL;DR: In this paper, a simplified mathematical model to simulate pollutant conversion in three-way catalytic converters is developed, that has a low computational load and ease of parametrization as primary priorities, but without completely disregarding the chemical background.
Journal ArticleDOI
Simulation of the transient CO oxidation over Rh0/SiO2 and Rhx+/Ce0.68Zr0.32O2 catalysts
Isabelle Manuel,Isabelle Manuel,Jérôme Chaubet,Cyril Thomas,Hervé Colas,Nils Matthess,Gérald Djéga-Mariadassou +6 more
TL;DR: In this paper, a detailed kinetic rate equation was established from the proposed catalytic sequences of elementary steps for transient CO oxidation by molecular oxygen, and a reliable estimation of CO light-off temperatures could be achieved.
