TAP investigation on methane conversion on supported Pd and Rh based catalysts – 1. Kinetics of methane adsorption

Autor: S. Pietrzyk, Y. Renème, F. Dhainaut, A.C. van Veen, Pascal Granger, M. Chaar

Publikováno v: Applied Catalysis B: Environmental. 126:239-248

The adsorption of methane on supported Pd- and Rh-based catalysts has been investigated by TAP experiments in the temperature range of 400–550 °C. Particular attention was paid to the effects related to thermal aging causing significant particle g

Kinetics of the NO/H2/O2 reactions on natural gas vehicle catalysts—Influence of Rh addition to Pd

Autor: Y. Renème, F. Dhainaut, Pascal Granger

Publikováno v: Applied Catalysis B: Environmental. :424-432

This paper reports an extensive kinetic study of the NO/H2 reaction on monometallic and bimetallic Pd and Rh based catalysts. The presence of oxygen in the feed has been examined and found to strongly alter the kinetic behaviour of noble metals accor
