CO2 Capture:Material design, Performance and Stability
Date: Wednesday, April 13th, 2016
Time: 11:00 AM
Location: Building 4, Room 125Speaker: Prof. Abdelhamid Sayari Department of Chemistry and Biomolecular Sciences, Department of Chemical and Biological Engineering, University of Ottawa, Canada Abstract: This presentation is a summary of our extensive work on the development and evaluation of nanoporous materials for the removal of CO2 from industrial gases and other sources, for further utilization or sequestration. It will be focussed on three items. - The rational design of adsorbent materials that meet all the requirements for efficient acid-gas removal and separation.
- This includes high adsorption capacity, high adsorption and desorption rates, low or no diffusion limitation, high stability
- and long lifetime.
- Experimental investigation and modelling of adsorptive properties, including adsorption equilibrium isotherms,
- kinetics, selectivity toward acid gases versus other gaseous components.
- Investigation of the materials stability, including the effect of ubiquitous impurities in industrial gases, such as
- water vapor,
- oxygen, sulfur oxide, etc, and mitigation thereof.
Biography: |
Dr. Abdelhamid Sayari is Professor of Chemistry and Chemical Engineering at the University of Ottawa, Canada, Fellow of the Canadian Institute of Chemistry, and Canada Research Chair in Nanostructured Materials for Catalysis and Separation. His is also the Founding Director of the Centre for Catalysis Research and Innovation at the University of Ottawa, and member of the Centre for Advanced Materials Research. He has been Editor of Journal of Molecular Catalysis since 2007. Dr. Sayari received his PhD in heterogeneous catalysis on a collaborative program between the University of Tunis and Université Claude Bernard in Lyon, France. After a postdoctoral fellowship at the University of Pittsburgh in the USA, he moved further North to join the National Research Council of Canada. In 1990, he became Professor of Chemical Engineering at Laval University in Quebec City. In 2001, he joined the University of Ottawa as a Canada Research Chair with the mandate to establish the Centre for Catalysis Research and Innovation. During his 35 year+ career, Dr. Sayari made outstanding contributions in many important areas of catalysis, including gas and liquid phase selective oxidation, ammoxidation, activation of light hydrocarbons including alkane dehydrogenation and methane aromatization, hydrotreating, isomerization, selective ring opening, Fischer-Tropsch synthesis, catalytic wet air oxidation and peroxidation, and biomass catalysis. He used a wide variety of catalysts, including zeolites, mixed oxides, supported metals and alloys, and solid superacid materials. More recently, he became an international leader in the synthesis of ordered nanoporous materials, their surface modifications and their applications in catalysis as well as in gas and liquid separation. Dr. Sayari developed and patented innovative materials for CO2 capture with unprecedented attributes. He published more than 250 refereed papers in leading journals of Chemical Engineering, Chemistry, Catalysis and Material Sciences. He also published seven book chapters and eight patents, and co-edited four books on mesoporous materials. He has an H-index of 68 and well over 16000 citations. |
