Topic: Plasma-based Greenhouse Gas Conversion: Modeling the Plasma Chemistry and Plasma Reactor Design to Improve the Application

Speaker: Prof. Annemie Bogaerts, Universiteit Antwerpen

Time:14:00-16:00, October 20

Venue:F102, New Main Building

Abstract:

Plasma-based greenhouse gas conversion (mainly CO2 and CH4) is gaining increasing interest. To improve this application in terms of conversion, energy efficiency and product formation, a good insight in the underlying mechanisms is desirable. We try to obtain this by computer modelling, supported by experiments. We simulate both the plasma chemistry as well as the optimum reactor design, in the three types of plasma reactors most commonly used for gas conversion, i.e., (packed bed) dielectric barrier discharges (DBDs), gliding arc (GA) discharges and microwave (MW) plasmas. For the plasma reactor design, we use 2D or 3D computational fluid dynamics modelling. For the plasma chemistry, we make use of zero-dimensional chemical kinetics modeling by which a detailed chemical kinetics analysis allows to elucidate the different pathways leading to the observed results. We also try to answer the question whether plasma can be formed inside catalyst pores, and what are the critical pore dimensions, by means of particle-in-cell Monte Carlo collision simulations of plasma streamer propagation inside catalyst pores.

Biography of the Speaker:

Prof. Annemie Bogaerts is currently committed to the study of plasma chemistry, plasma reactor design and plasma-surface interactions, by numerical modelling and experiments, for various applications, especially environmental applications (CO2 conversion into value added chemicals and renewable fuels, and nitrogen-fixation from the air for the production of small chemical building blocks) as well as medical applications (mainly cancer treatment).

She is author of more than 400 publications, and she has more than 9,000 citations (Web of Science; h-index 47) and 13,000 citations (Google Scholar; h-index 58). She gave more than 200 invited talks at international conferences and research institutes. She is editor of Spectrochimica Acta B, responsible for the review papers, and guest editor for 10 special issues in several journals. She is also in the advisory/editorial board of several journals, and in the international scientific committee of many international conferences. In 2015 she was the Chair of the International Symposium on Plasma Chemistry (ca. 600 participants), and she is also a member of the Board of Directors of the International Plasma Chemistry Society.
