Journal Article
Adam, M., Anbari, H., Hart, A., Wood, J., Robinson, J. P., & Rigby, S. P. (2021). In-situ Microwave-assisted Catalytic Upgrading of Heavy Oil: Experimental Validation and Effect of Catalyst Pore Structure on Activity. Chemical Engineering Journal, 413, Article 127420. https://doi.org/10.1016/j.cej.2020.127420

In-situ combustion alone may not provide sufficient heating for downhole, catalytic upgrading of heavy oil in the Toe-to-Heel Air Injection (THAI) process. In this study, a new microwave heating technique has been proposed as a strategy to provide th...

Predicting Surface Diffusivities of Gas Molecules in Shale (2020)
Journal Article
Spanakos, D., & Rigby, S. P. (2020). Predicting Surface Diffusivities of Gas Molecules in Shale. Energy and Fuels, 34(10), 12417-12428. https://doi.org/10.1021/acs.energyfuels.0c02441

Carbon dioxide injection can be utilized as a means of both enhancing gas recovery from shales and sequestering carbon and thereby simultaneously addressing the growing worldwide gas demand, as well as the challenge of greenhouse gas emissions. Great... Read More about Predicting Surface Diffusivities of Gas Molecules in Shale.

Structural and chemical heterogeneity in ancient glass probed using gas overcondensation, X-ray tomography, and solid-state NMR (2020)
Journal Article
Rigby, S. P., Stevens, L., Meersmann, T., Pavlovskaya, G. E., Rees, G. J., Henderson, J., Bryant, S. J., Edler, K. J., & Fletcher, R. S. (2020). Structural and chemical heterogeneity in ancient glass probed using gas overcondensation, X-ray tomography, and solid-state NMR. Materials Characterization, 167, Article 110467. https://doi.org/10.1016/j.matchar.2020.110467

Rare ancient glasses have complex, multi-scale structures requiring more sophisticated and non-destructive pore characterisation techniques than usual. Homotattic patch models for nitrogen adsorption gave better fits to the isotherm data, more accura...
