TL;DR: In this paper , an efficient and sustainable treatment of sewage sludge was achieved using plasma-electrolytic liquefaction (PEL) with alkaline catalysts including sodium hydroxide (NaOH), sodium carbonate (Na2CO3), and sodium acetate(NaAc) and renewable solvents including polyethylene glycol (PEG) 200 and glycerol.
Conversión hidrotérmica subcrítica de residuos Conversión hidrotérmica subcrítica de residuos orgánicos y biomasa. Mecanismos de reacción orgánicos y biomasa. Mecanismos de reacción Subcritical hydrothermal conversion of organic wastes and biomass. Reaction pathways
TL;DR: The main component of biomass (depolymerisation by hydrolysis) is presented in hydrothermal cellulose conversion, producing oligosaccharides which exhibit dehydration and retro-aldol condensation reactions for transforming into furfurals and carboxylic acids as discussed by the authors.

Assessing a hydrothermal liquefaction process using biomass feedstocks
TL;DR: In this article , the authors conducted liquidation experiments on dairy manure collected from the Louisiana State University Dairy Farm in Baton Rouge, using various temperatures (250-350°C) and catalysts (Na2CO3, NaOH, and K2Co3) to determine optimum operating conditions for these two parameters.
