Simulation of Carbon Deposition on Ni Catalyst: Applications to Methane Catalytie Cracking and Solid Oxide Fuel Cell (SOFC) Button Cell Modelling



Time: 10.00-12.00 a.m., April 3rd, 2019, Wednesday

Venue: Conference Room, 5th floor, Block C, Multidisciplinary Building

Speaker: Prof. Eric Croiset, Chair of Chemical Engineering Department, University of Waterloo, Canada


Abstract:

Ni catalysts are widely used in several catalytic processes. such as reforming, due to its high activity. However. when using carbon-containing feedstock, Ni is notoriously prone to coke deposition. This negatively impacts the process (e.g. natural gas reforming, SOFC operating on hydrocarbon fuels), whereas this characteristic can be used on purpose, such as in methane catalytic cracking. ln this seminar two different applications of carbon deposition modeling will be presented: the first application relates to methane catalytic cracking where methane decomposes in hydrogen and carbon, the latter forming filamentous carbon. The second application is concerned with the modeling investigation of carbon deposition when SOFC operates on methane or syngas.
