Dr. F. Handan Tezel leads the Energy-S.M.A.R.T. team (Energy-Storage, Membranes, Adsorption Research and Technology), composed of graduate (Ph.D. candidate and M.A.Sc. candidate) and undergraduate (B.A.Sc. candidate) students.
They work together in the Chemical and Biological Engineering laboratories in the Colonel By building located on the University of Ottawa campus in downtown Ottawa, ON.

Separation of Carbon Dioxide, Nitrogen, and Methane Gases Using Adsorption Processes
Dean is currently investigating the use of adsorption technology for bulk industrial gas separation and purification. His current research involves determining the single component adsorption capacities and selectivity of CO2, N2 and CH4 for different types of commercially available adsorbents. Following his screening analysis, gas mixture breakthrough experiments will be performed using selected promising adsorbents that will be analysed in terms of industrial and economic feasibility. The development of a novel inorganic adsorbent membrane will then be investigated using the most promising adsorbent from the initial screening study.
Separation of Greenhouse Gases Using Inorganic Silicalite Membranes
For inorganic membranes composed of silicalite operated at ambient temperatures, each gas in a mixture fed to a membrane adsorbs to the membrane at a different rate. Consequently, the gas which is preferentially adsorbed is concentrated and separated from the feed mixture, as required for further treatment. This enables the separation of multicomponent gas streams as needed to treat waste products such as the greenhouse gases carbon dioxide (CO2) and methane (CH4). My research is on the fabrication and characterization of membranes to separate carbon dioxide and methane from gas mixtures, and in doing so promote the implementation of inorganic membranes to mitigate the effects of global warming.
Thermal Energy Storage (TES) for Space Heating and Cooling Applications
Energy can be stored in many forms: mechanical, chemical, electrochemical, biological, magnetic, and thermal. Thermal energy storage provides an alternative method to store energy generated from intermittent renewable energy sources and correct for the variable supply and demand. The thermal energy storage device can also be charged with surplus electricity during non-peak hours, discharge and release the heat during peak hours. Our current work investigates the thermal energy storage technology for space heating and cooling applications using water vapor adsorption process in porous materials.
