Techno-economic and uncertainty analysis of biomass to liquid (BTL) systems for transport fuel production (2018)
Journal Article
Dimitriou, I., Goldingay, H., & Bridgwater, A. V. (2018). Techno-economic and uncertainty analysis of biomass to liquid (BTL) systems for transport fuel production. Renewable and Sustainable Energy Reviews, 88, doi:10.1016/j.rser.2018.02.023. ISSN 1364-0321

This work examines the technical and economic feasibility of Biomass-To-Liquid (BTL) processes for the manufacture of liquid hydrocarbon fuels. Six BTL systems are modelled and evaluated which are based on pressurised oxygen gasification of woody bio... Read More

Pyrolysis of plastic waste for production of heavy fuel substitute: a techno-economic assessment (2018)
Journal Article
Fivga, A., & Dimitriou, I. (2018). Pyrolysis of plastic waste for production of heavy fuel substitute: a techno-economic assessment. Energy, 149, doi:10.1016/j.energy.2018.02.094. ISSN 0360-5442

Pyrolysis is widely seen as a promising technology for converting plastic waste into a wax/oil product which can be used as a heavy fuel oil substitute or as raw material by the petrochemical industry. A pyrolysis plant with a capacity of 100 kg/h pl... Read More

Kinetic and economic analysis of reactive capture of dilute carbon dioxide with Grignard reagents (2015)
Journal Article
Dowson, G., Dimitriou, I., Owen, R., Reed, D., Allen, R. W., & Styring, P. (2015). Kinetic and economic analysis of reactive capture of dilute carbon dioxide with Grignard reagents. Faraday Discussions, 183, doi:10.1039/C5FD00049A. ISSN 1359-6640

Carbon Dioxide Utilisation (CDU) processes face significant challenges, especially in the energetic cost of carbon capture from flue gas and the uphill energy gradient for CO2 reduction. Both of these stumbling blocks can be addressed by using alkali... Read More

Carbon capture and utilisation: application of life cycle thinking to process design (2015)
Conference Proceeding
Cuellar-Franca, R., Dimitriou, I., Garcia-Gutierrez, P., Elder, R. H., Allen, R. W., & Azapagic, A. (2015). Carbon capture and utilisation: application of life cycle thinking to process design

Applying life cycle thinking at an early design stage can help engineers to deliver sustainable systems by design. To demonstrate how this can be carried out at a practical level, this paper proposes a simplified methodology for integrating life cycl... Read More

Supercritical extraction as an effective first-step in a maize stover biorefinery (2015)
Journal Article
Attard, T. M., Theeuwes, E., Gomez, L. D., Johansson, E., Dimitriou, I., Wright, P. C., …Hunt, A. J. (in press). Supercritical extraction as an effective first-step in a maize stover biorefinery. RSC Advances, 5(54), doi:10.1039/C5RA07485A. ISSN 2046-2069

Supercritical carbon dioxide (scCO2) has been investigated for the generation of valuable waxy compounds and as an added-value technology in a holistic maize stover biorefinery. ScCO2 extraction and fractionation was carried out prior to hydrolysis a... Read More
