Harnessing Activated Sludge for the Treatment of Hydrothermal Liquefaction Wastewater: A Proof-of-Concept Study. [PDF]

Water Environ Res
Activated sludge cultivation for sewage sludge HTL wastewater treatment was optimized using high temperature incubation, nutrient supplementation, high dilution factor, and overliming pretreatment. Up to 91.2% sCOD removal was achieved, with kinetics analysis confirming enhanced degradation rates under treatment optimization.

Recycling of Polyurethane Waste: Facile Hydrothermal Conversion Using Acidic and Basic Additives. [PDF]

ChemSusChem
Ethylenediamine efficiently catalyses the hydrothermal recycling of polyurethane (PU) into monomers. The NH functional groups promote carbamic acid decomposition via zwitterion interactions, outperforming inorganic acids and bases, and enabling selective depolymerisation of PU under mild conditions for circular chemical utilisation.

Treatment of Hydrothermal-Liquefaction Wastewater with Crossflow UF for Oil and Particle Removal

Membranes, 2022
This study aims to evaluate the application of ceramic ultrafiltration membranes in the crossflow mode for the separation of particles and oil in water emulsions (free oil droplets and micelles) from hydrothermal-liquefaction wastewater (HTL-WW) from the

Effects of Water and Air on the Reaction Pathways in the Hydrothermal Liquefaction of Plastics. [PDF]

ChemSusChem
Is water an innocent solvent for the hydrothermal liquefaction (HTL) of plastics? Does it also react with plastic under supercritical conditions? Only in the absence of oxygen does water appear to be the former. Despite observations that residual oxygen under HTL conditions is the sole source of oxidized reaction products, several aspects of the ...

Molecular footprint of co-solvents in hydrothermal liquefaction (HTL) of Fallopia Japonica [PDF]

The Journal of Supercritical Fluids, 2019
The influence of co-solvents on hydrothermal liquefaction (HTL) of Fallopia Japonica was studied as a function of temperature. Combination of low and high-resolution mass spectrometry with multi-layered data mining strategy resulted in a comprehensive characterization of the reaction products, mostly water-soluble organics (WSO) with a broad spectrum ...

Protocol to develop component additivity models that predict oil yield from hydrothermal liquefaction

STAR Protocols, 2022
Summary: Here, we describe steps for performing hydrothermal liquefaction (HTL) experiments and developing component additivity models that predict oil yields from HTL of mixtures with biomass and plastics.

Component additivity model for plastics—biomass mixtures during hydrothermal liquefaction in sub-, near-, and supercritical water

iScience, 2021
Summary: We produced oils via hydrothermal liquefaction (HTL) of binary mixtures of biomass components (e.g., lignin, cellulose, starch) with different plastics and binary mixtures of plastics themselves.

Modification of a pilot-scale continuous flow reactor for hydrothermal liquefaction of wet biomass

MethodsX, 2019
A pilot-scale continuous flow reactor (CFR) was modified for hydrothermal liquefaction (HTL) of algae slurry under subcritical conditions to investigate the feasibility of scaling up from batch to continuous processing.

Catalytic hydrothermal liquefaction of microalgae over metal incorporated mesoporous SBA-15 with high hydrothermal stability

Carbon Resources Conversion, 2018
Hydrothermal liquefaction (HTL) is one of the most promising technologies for conversion of microalgae, and catalysts with high hydrothermal stability are required for controllable HTL. In this article, SBA-15 incorporated with transition metals (Ni, Pd,
