A comparison of batch extracted bio-oil and continuous hydrothermal liquefaction bio-oil using spent coffee grounds as biomass feedstock

Jansen van Rensburg, T.; Schabort, C.J. (EARET, 2018)

This study focuses on bio-oil obtained from spent coffee grounds, either by reflux extraction or continuous hydrothermal liquefaction. Spent coffee grounds was chosen as feedstock for this study as it is available around ...
The effect of aqueous phase recirculation during hydrothermal liquefaction of spent coffee grounds

Grobler, J.J.; Schabort, C.J. (EARET, 2018)

Batch hydrothermal liquefaction of spent coffee grounds was done in this study. The effect of subsequent diluted aqueous phase recirculation was studied at a constant temperature of 275 °C and residence time of 10 ...
The evaluation of spent coffee grounds as feedstock for continuous hydrothermal liquefaction

Von Wielligh, J.; Schabort, C.J.; Venter, R.; Marx, S. (EARET, 2018)

This study looks at converting a low-value waste in a continuous hydrothermal liquefaction reactor to a high-value biocrude and biochar product. The feedstock chosen for this study was spent coffee grounds (SCG) as spent ...
