Microwave pyrolysis of olive pomace for bio-oil and bio-char production (2019)
Journal Article
Williams, O. S., Kostas, E. T., Durán-Jiménez, G., Shepherd, B. J., Meredith, W., Stevens, L. A., …Lye, G. J. (2020). Microwave pyrolysis of olive pomace for bio-oil and bio-char production. Chemical Engineering Journal, 387, Article 123404. https://doi.org/10.1016/j.cej.2019.123404

Olive pomace is a widely available agro-industrial waste residue in Europe that has the potential to contribute towards a circular, low carbon bio-economy. This study demonstrated, for the first time, the ability to successfully pyrolyse olive pomace... Read More about Microwave pyrolysis of olive pomace for bio-oil and bio-char production.

Automated image analysis techniques to characterise pulverised coal particles and predict combustion char morphology (2019)
Journal Article
Perkins, J., Williams, O., Wu, T., & Lester, E. (2020). Automated image analysis techniques to characterise pulverised coal particles and predict combustion char morphology. Fuel, 259, https://doi.org/10.1016/j.fuel.2019.116022

A new automated image analysis system that analyses individual coal particles to predict daughter char morphology is presented. 12 different coals were milled to 75-106 µm, segmented from large mosaic images and the proportions of the different petro...

Formation of Metallurgical Coke within Minutes through Coal Densification and Microwave Energy (2019)
Journal Article
Williams, O., Ure, A., Stevens, L., Binner, E., Dodds, C., Kingman, S., …Lester, E. (2019). Formation of Metallurgical Coke within Minutes through Coal Densification and Microwave Energy. Energy and Fuels, 33(7), 6817-6828. https://doi.org/10.1021/acs.energyfuels.9b00511

This paper shows how feedstock densification gives rise to a step change in the time required to create a metallurgical grade coke using microwave energy. Five densified coking and non-coking coals were heated in a multi-mode microwave 2450 MHz cavit...

The impact of ash pellet characteristics and pellet processing parameters on ash fusion behaviour (2019)
Journal Article
Daley, P., Williams, O., Pang, C. H., Wu, T., & Lester, E. (2019). The impact of ash pellet characteristics and pellet processing parameters on ash fusion behaviour. Fuel, 251, 779-788. https://doi.org/10.1016/j.fuel.2019.03.142

The Ash Fusion Test (AFT) is considered to be the most popular method of characterising the melt characteristics of solid fuel ash. This study shows how pellet preparation can make significant improvements to repeatability. Pelleting pressure, pellet...

Microwave pyrolysis of Laminaria digitata to produce unique seaweed-derived bio-oils (2019)
Journal Article
Kostas, E. T., Williams, O. S., Duran-Jimenez, G., Tapper, A. J., Cooper, M., Meehan, R., & Robinson, J. P. (2019). Microwave pyrolysis of Laminaria digitata to produce unique seaweed-derived bio-oils. Biomass and Bioenergy, 125, 41-49. https://doi.org/10.1016/j.biombioe.2019.04.006

Microwave pyrolysis has become an attractive form of processing technology to generate bio-oil, bio-char and syngas from different biomass feedstocks. In this study, microwave pyrolysis was performed on the UK native seaweed Laminaria digitata and it...
