Introductory Plenary Lectures 2019

We are happy to introduce the following plenary speakers for MODEGAT VI:


Prof. Petr Kočí, University of Chemistry and Technology, Prague, Czech Republik

Associate professor at University of Chemistry and Technology, Prague (UCTP), Department of Chemical Engineering. His research interests include multi-scale mathematical modeling of transport, reactions and transformations in porous catalysts and filters with applications in automotive exhaust gas conversion. Petr Kočí obtained his Ph.D degree in Chemical Engineering at UCTP in 2005. He has published about 50 papers in impacted scientific journals and worked on research projects with several academic and industrial partners, including Oak Ridge National Laboratory, Daimler, Johnson Matthey, Ecocat, Umicore and Corning.

Plenary talk title: Multi-scale modeling of catalytic particulate filters for gasoline engines (GPF)


Prof. Grigorios Koltsakis, Aristotle University, Thessaloniki, Greece

Dr. Grigorios Koltsakis received his Diploma and Ph.D from the Department of Mechanical Engineering of Aristotle University of Thessaloniki. He is currently a Professor at the Laboratory of Applied Thermodynamics of Aristotle University, specializing in Internal Combustion Engines and exhaust after-treatment technology. He has authored more than 100 papers in scientific Journals and international conferences and holds 2 patents. Dr Koltsakis has received the Arch T. Colwell Merit Award as well as two Oral presentation awards from SAE International. He has also received the first Innovation prize from the Research Committee of Aristotle University. Dr Koltsakis leads a research group active in the simulation and evaluation of after-treatment technologies in close collaboration with the international automotive industry. He is a co-founder and scientific director of Exothermia SA, a University spin-off company developing emission control system simulation software.

Plenary talk title: Challenges and model-based solutions in SCR-coated filters applications

Dr. Ton V. W. Janssens, Umicore Denmark, Kgs  Lyngby., Denmark

Dr. Ton V. W. Janssens pursued an education in Chemical Engineering at the University of Technology Eindhoven (NL) and obtained his Ph.D from the same university, in a collaboration project with the University of Bonn(D), studying the electrostatic effects of alkali promoters on a Rh(111) surface. He has spent 2 years at the University of California, Riverside and 1½ year at the Fritz Haber Institute, in Berlin, working on reactions of hydrocarbons on Pt and Pd surfaces. Having joined Haldor Topsøe A/S in 1998, he mainly worked on the development of catalysts for hydrogen production, Au catalysts, and methanol-to-gasoline processes. He then changed to the automotive department at Topsøe in 2012 and shifted his focus to NH3-SCR and ammonia slip catalysts. In 2017, he followed the transfer of the Topsoe automotive catalysis to Umicore Denmark, continuing the work on automotive catalysis for heavy-duty diesel vehicles.

Plenary talk title: Mechanism of the selective catalytic reduction of NOx by ammonia on Cu-CHA

L. Lietti

Prof. Luca Lietti, Politecnico di Milano, Milano, Italy

Luca Lietti has been full Professor of Chemical Engineering at Politecnico di Milano since March 2001. Graduated in chemical engineering at the Politecnico di Milano in 1985, he earned his doctorate in industrial chemistry at Politecnico di Milano in 1989. From 1989 to 1992 he was Post-doc at the Department of Industrial Chemistry and Chemical Engineering, Politecnico di Milano, where he became Assistant professor in 1992. From October 1993 to April 1994 he was Visiting Scientist at Lehigh University (PA), USA, working with Prof. Kamil Klier. In 1998 he was appointed professor of Industrial Catalysis at the Department of Chemistry, Materials and Chemical Engineering, Politecnico di Milano, and in 2001 he became full professor at the same department. In 2008 he moved to the Dept. of Energy of the same University.

His major interests are in heterogeneous catalytic processes, especially for energy and the environment. Current researches include NOx abatement in mobile and stationary sources, CO2 hydrogenation to fuels and chemicals, Fischer-Tropsch synthesis over Co- and Fe-based catalysts, catalytic soot oxidation and combined soot-NOx removal.

He has published more than 200 ISI-classified publications, several review articles appeared as books chapters and 3 patents. He edited the book entitled “NOx trap catalysts and technologies: fundamentals and industrial applications”, published by RSC in 2018.

Plenary talk title: NOx adsorption in DeNOx aftertreatment systems
