Biogas is a major source of greenhouse gas emissions worldwide, particularly since methane (its main component) is ~28 times more potent than CO₂ in trapping heat in the atmosphere. Upgrading biogas to renewable natural gas or bio-methane, would mitigate these emissions while also harnessing the energy potential of anthropogenic waste. This requires the biogas stream to be purified from roughly 60% to at least 90% methane, removing CO₂ and other contaminants in the process. Among all available technologies, including scrubbing, membranes and adsorption processes, the latter offer higher energy efficiency and comparatively low cost. However, the effectiveness of adsorption processes hinges on the optimal selection of adsorbent material. This project aims to deploy a unique combination of molecular modelling, data science and experimental methods to: 1) find the ideal adsorbent for biogas upgrading under realistic industrial operating conditions, using data-based computational screening informed by molecular simulations; 2) scale-up and shape the material(s) identified in step 1; 3) select and optimise the required adsorption process for industrial-scale upgrading of biogas using process modelling methods. This strategy will enable us to cover all aspects of the material design workflow, from molecular-level understanding of the adsorption mechanism, all the way to performance prediction and life-cycle analysis.

This project is a partnership between the University of Strathclyde and King Abdullah University of Science and Technology (KAUST), specifically with the group of Prof Carlos Grande. The experimental parts of the project will be carried out by the KAUST team, while the modelling aspects will be conducted at Strathclyde. Visits to the partner institution may be required.

You will join a world-leading team of researchers to design the next generation of porous materials for industrial separations. You will be trained in cutting edge computer simulation methods, including high-performance computing, as well as data handling and processing skills, both of which will address current skills gaps leading towards digitalisation of research.

In addition to undertaking cutting edge research, students are also registered for the Postgraduate Certificate in Researcher Development (PGCert), which is a supplementary qualification that develops a student’s skills, networks and career prospects.
