Adsorbent screening for CO2, N2, and O2 for Landfill Gas separation by Adsorption

The proposed project would seek 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) produced from landfills, using adsorption technology. Interns will be carrying out adsorbent screening, by determining kinetics and binary and multi-component adsorption behaviour. Promising adsorbents will then be selected and tested under cyclic conditions to determine their life cycle. We will be in a position to propose the best adsorbent for this application. Model will be developed and validated for this separation. This model will be used to design larger scale separation systems. This technology has the potential of valorizing the biogas generated in anaerobic digesters and helps in efforts to divert food and organic waste away from landfills and reduce the amount of food waste going into landfills.
