This paper investigates the production of biocrude via hydrothermal liquefaction (HTL) sewage sludge. Results on effect separation protocol oily/aqueous phases highlighted superior performance inertial over liquid–liquid extraction, with a yield 43% attained at HTL temperature 350 °C. Experimental results revealed that processing time exerts nonmonotonic maximum yields 35 and after 30 10 min times 300 °C, respectively. The best in terms energy recovery (about 59%) reduced content S 1%) are obtained A minimum water-soluble compounds (29%) is achieved whereas (49%) same temperature. From both NMR LC-MS analyses, proved to be complex mixture mainly constituted by aliphatic compounds, small amounts aromatic (including PAHs) olefins. Finally, inorganic elements present sludge report entirely solid phase.

Hydrothermal liquefaction (HTL) emerges as an efficient technology for converting food waste into biocrude. Among HTL parameters, the impact of heating rate is understudied. This study systematically explores its variation (5-115 K/min) on performance using actual and model compounds representing constituents. Results revealed that increase in rates significantly impacts performances (+63 % biocrude -34 solid with waste) short residence times, slower imply a longer overall time higher kinetic advancement reaction. Conversely, influence becomes negligible, kinetics during times are overshadowed by those at operating temperatures. A subtle effect extended was observed only carbohydrates. research emphasizes utility severity factor (KSF) valuable tool simultaneously considering rates,

Uncontrolled emission of carbon and nutrients due to mismanagement dairy waste leads global warming, eutrophication water bodies, aerosol pollution, acidification ecosystems. We studied hydrothermal liquefaction (HTL) sustainably recover resources by converting the wastes into carbon-dense biocrude oil a nutrient-rich aqueous-phase coproduct. evaluated acid whey as an alternative source catalyst, replacing acetic acid, for HTL anaerobically digested cattle manure (manure digestate). Using well-designed experiments, we investigated effects several factors on product formation fate elements well underlying chemistry. The included reaction temperature (280–360 °C), time (10–50 min), mixing ratio digestate (AW/MD 0–2), amount additional required, that is, specified based final feedstock pH between 3.5 5.5. experimental results suggested following optimal conditions enhanced maximal nutrient yield in coproduct: AW/MD 1.21, mixture 4.5, 354 °C 21 min, respectively. Under such conditions, was 40–50% (equivalent 60–80% energy recovery) via cyclic acetalization, hydroxymethylation, isomerization, Piancatelli rearrangement, oxidation, condensation with heteroatom removal deoxygenation denitrogenation mechanisms. Moreover, these provided adequate solubilize Mg-carbonate Ca-phosphate minerals catalyzed deamination N-heterocyclics other nitrogenous compounds, producing higher recoverable Mg, NH3-N, P, K coproduct, 60–70, 30–40, ∼40, >95%, This study demonstrated potential using coprocessing measurably valorize biomass key component achieving circular bioeconomy industry.

We studied the hydrothermal liquefaction (HTL) of digested sewage sludge (DSS) as model waste biomass in batch and continuous reactors. HCOOH KOH were used to improve slurry pumpability. HTL experiments conducted at same kinetic severity factor a reactor 25 mL volume continuously operated tubular with 350 volume. The observed outcomes suggested that it was not possible achieve pumpability native DSS when high concentrated stream suspended solid particles has been fed plant. Using acidic or basic homogeneous additives, potassium hydroxide formic acid, enhance plant achieving yields heavy oil (fraction biocrude) similar those obtained higher H/C ratios. Hence, we found are promising additives for practical implementation process.

Electrospray ionization fourier transform ion cyclotron resonance mass spectrometry was applied to evaluate the organic oxygen composites (OOCs) in methanol fraction derived from supercritical alcoholysis of original and pretreated straw (WS) utilizing Trichoderma sp. AH. In methanol-soluble (MSF) untreated preconditioned WSs, O n (n = 1–10), with double bond similar values 1–28 carbon atom numbers 4–35, most predominant OOCs negative mode. 5 4 were prominent MSF WS, respectively. These results assist comprehending impact AH pretreatment on specificity, transformation WS application manufacture fuel source.
