Production of Natural Gas from Renewable Sources using Adsorption Technology
Amirhosein’s research is focused to develop a technology and identify adsorbents that are better able to remove impurities such as carbon dioxide (CO2), nitrogen (N2), and oxygen (O2) from biogas (mostly CH4, also referred to as natural gas) at different system total pressures for different concentrations using adsorption technology. His research will be carrying out adsorbent screening, by determining pure component and mixed gas adsorption isotherm data. Promising adsorbents will then be selected and tested to obtain and look at adsorbents’ performance data when treating different gas mixtures in fixed bed adsorption systems. Concentration pulse chromatographic technique will be used to determine binary mixture isotherms of these gases with the chosen adsorbents. Breakthrough curves will also be determined using multicomponent mixtures of the above mentioned gases.
Separation of Carbon Dioxide, Nitrogen, and Methane by Adsorption
Adsorption for the separation of gases is attractive due to its relatively low capital cost and energy requirements compared to absorption or distillation. Our current research involves determining the single adsorption capacities of CO2, N2, and CH4 for commercially available adsorbents, as well as the binary adsorption capacities of CO2 and N2 in the presence of CH4. After identifying promising adsorbents from these tests, breakthrough experiments will be completed to assess their performance for multicomponent mixtures.
Porous Nanostructures for Space Heating and Cooling
Adsorption thermal energy storage is an emerging technology used in space heating and cooling applications. The thermal energy storage group focuses on a different class of porous adsorbent materials such as silica gel, zeolites, activated carbon, etc., and studies their thermal energy storage properties. We are also analyzing how the porosity, pore-volume, and surface area of the materials affect the water uptake capacity and energy storage density of the adsorption materials.
