Electrocarboxylation in supercritical CO2 and CO2-expanded liquids [PDF]
The Journal of Supercritical Fluids, 2008 Abstract In this study, the electrocarboxylation of benzyl chloride in pressurized CO 2 , or pressurized mixtures of dimethylformamide (DMF) and CO 2 , was investigated in order to synthesize phenylacetic acid. A stainless steel cathode was used as the working electrode, whereas a sacrificial massive magnesium rod or a platinized platinum grid was ...

Displacement dewatering of sludge with supercritical CO2
Water Research, 2021 Supercritical CO2 (sCO2) displaces water from wastewater, alum, and papermill sludge. The sCO2 appears to enter the sludge matrix through viscous fingering through the entrained water. Because the water removed far exceeds the solubility of water in sCO2, it must be displaced by the sCO2 rather than dissolved out.
