Journal ArticleDOI
A Comprehensive Model to Predict Three-Way Catalytic Converter Performance
TL;DR: In this article, the authors describe the development of a comprehensive mathematical and numerical model for simulating the performance of automotive three-way catalytic converters, which are employed to reduce engine exhaust emissions.

Effect of Pt:Pd ratio on CO and hydrocarbon oxidation
Sung Bong Kang,Melanie J. Hazlett,Vemuri Balakotaiah,Christos M. Kalamaras,William S. Epling +4 more
TL;DR: In this article, the effect of the Pt:Pd ratio on a diesel oxidation catalysts ability to oxidize CO and different hydrocarbon types was investigated, where the concentrations and types of pollutant species were used to simulate those found in low temperature combustion (LTC) engine exhaust.
Journal ArticleDOI
Transient behaviour of catalytic monolith with NOx storage capacity
TL;DR: In this article, a spatially 1D, heterogeneous mathematical model of catalytic monolith with NOx and oxygen storage capacity is described, and the minimum set of experiments needed for the evaluation of relevant reaction kinetic parameters is discussed.
Journal ArticleDOI
Size-dependent CO and propylene oxidation activities of platinum nanoparticles on the monolithic Pt/TiO2–YOx diesel oxidation catalyst under simulative diesel exhaust conditions
TL;DR: In this paper, the CO and C3H6 oxidation rates of size-selected Pt nanoparticles (1 nm ultrafine size and 8.8 nm nanoscale size average diameters) deposited on TiO2-YOx supports were determined by transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and H2 temperature-programmed reduction (H2-TPR).
Journal ArticleDOI
3D reconstruction and pore-scale modeling of coated catalytic filters for automotive exhaust gas aftertreatment
Petr Kočí,Petr Kočí,Martin Isoz,Martin Isoz,Marie Plachá,Adéla Buzková Arvajová,Marek Václavík,Miloš Svoboda,Emily Price,Vladimír Novák,David Thompsett +10 more
TL;DR: In this paper, the pore-scale simulation of flow, diffusion and reaction in a coated catalytic filter is presented, where the simulation results suggest that the gas predominantly flows through remaining free pores in the filter wall and cracks in the coated layer.
