The current most difficult challenge of biomass-based wastes is the lack of a volume-balancing set of applications and valorisation techniques which can decrease the large volumes that are sent to the landfill. Valorisation of such residues to produce either energy, materials or/and chemicals is a priority research challenge that needs to be addressed to overcome the current two most critical environmental issues: waste management and GHGs (Green House Gases) emissions mitigation.
In line with the latter, this PhD project will focus on the study of different routes towards the conversion of biomass-waste into added-value porous bio-adsorbents. The main aim is to produce sustainable and cost-effective biomass-based materials for their application in gas separation processes, such as carbon capture. Accordingly, a comprehensive analysis on the properties of the produced bio-adsorbents, their suitability for the selected CO2 capture application (i.e. high CO2 uptakes and selectivity, high working capacity, fast adsorption/desorption kinetics, thermal and mechanical stability, low regeneration temperatures), and the evaluation of the sustainability of the valorisation process(es) employed (from start-to-end), will be performed in order to conclude on the best valorisation route(s).
The selected candidate will develop, characterise and test the bio-adsorbents for CO2 capture, which will involve the development of adsorbents from biomass wastes, their chemical and textural characterisation, evaluation of gas adsorption at equilibrium, and CO2 capture at dynamic conditions, using the existing experimental facilities.
Selection will be made on the basis of academic merit. The successful candidate should have, or expect to obtain, a UK Honours degree at 2.1 or above (or equivalent) in Chemical Engineering or any related discipline, such as BSc in Chemistry, Physics, Materials Science.
