The present study deals with thermo-catalytic co-pyrolysis of peanut shells (PS) and non-recyclable polyethylene (NRPE) using ZSM-5 at varying ratios (5, 10 15 wt.%). A tubular fixed bed reactor is used to pyrolyse 500 oC, 50 oC min-1 heating rate 100 mL inert gas flow rates. feedstock was characterized via proximate analysis, elemental higher value (HHV), biochemical thermogravimetric analyser (TGA), Fourier transforms infrared spectroscopy (FTIR) viscosity, density, Gas chromatography-mass spectrometry (GC-MS), BET surface area, water holding capacity (WHC). Co-pyrolysis results confirmed maximum liquid yield (34.50%) wt.% NRPE; however, adding wt% again boosted the oil by 7.87 wt.%. Pyrolytic characterization that NRPE decreased acidity, density. However, carbon content, ash content increased. FTIR examinations PS hydrocarbons, acids, water, oxygenated compounds. GC-MS were wt%; hydrocarbon furfural increased 5.31 5.46%, whereas 6.01% acids compounds decreased, respectively. char characterisation further supported findings (10 wt.%) enhanced HHV 11.86% 4.35 MJ kg-1 oxygen bulk density 0.75%, 10.21%, 71.98 kg m-3,

Co-hydrothermal carbonization (co-HTC) is a promising strategy to improve hydrothermal (HTC) of low-quality wastes.HTC swine manure (SM), with high N (2.9 wt%), S (0.7 wt%) and ash (22.6 contents, as well low C (35.6 higher heating value (HHV; 14.3 MJ kg -1 ), resulted in hydrochar unsuitable characteristics solid fuel.Co-HTC SM garden park waste (GPW) improved properties (C content (43 -48 HHV (18 -20 decreased (~2 (<0.3 (<15 content.A GPW ratio (>50 during co-HTC similar that obtained from GPW.The increased nutrient migration the process water, which allowed precipitation salt P (7.8 negligible heavy metal content.Anaerobic digestion water organic matter removal (up 65%), methane production (315 -325 mL CH 4 g COD added ).Gross energy recovery by HTC anaerobic was 5 -6-fold than treatment feedstocks.Therefore, > 50% proved be suitable approach valorize manage obtain value-added products (hydrochar, mineral fertilizer methane).

This study aims to obtain a carbonaceous material with suitable properties be used as solid biofuel by recycling process water from hydrothermal carbonization (HTC) of garden and park waste (GPW). The research is focused on maximizing mass yield energy recovery well facilitating the treatment liquid fraction throughout reusing cycles fraction. Process moderately improved performance hydrochar, resulting in higher almost 20 percentage points compared that achieved (less than 79%) conventional HTC (GPW + freshwater feed). An improvement char fuel quality was observed, showing more morphological, physical, chemical characteristics, reactivity combustion temperature, lower probability ash sintering. Successive reuse allowed some increase but, at same time, degraded hydrochar biofuel. composition showed an oxygen demand total organic carbon, which doubled after three successive cycles. concentration volatile fatty acids increased around 5-fold (up g L–1), acetic acid accounting for 85% total. Subsequent anaerobic digestion removed up 75% COD yielded biogas high methane content (225–302 N mL CH4 g–1 CODadded). Recycling significantly (hydrochar methane) 90% single recycling, 84% subsequent water.

Abstract Limited information is available about potential physicochemical changes that can occur in hydrochar post-production, e.g. during drying and storage. Understanding these crucial not just for shaping future research plans, but also practical applications. Here we studied the effect of moisture (69.2% 2.4%) three storage temperatures (− 18, 4, 20 °C) over a year on selected organic inorganic compounds produced from Hydrothermal carbonization (HTC) digested cow manure. Comparison control wet hydrochars (WHs) dry (DHs) showed compound composition due to drying. Overall, total amount was notably greater WH (15.2 g kg −1 DM) compared DH (11.8 DM), with variations observed individual concentrations. Drying, however, had no significant influence identified compounds. Storage caused both DH, particularly after 12 weeks. Sugars (2–sevenfold), acids (36–371%), aromatics (58–120%) stored samples at week 52 were significantly higher than their values. Changes elements (e.g., Co, K, Mg, Mn, P, S, Sr, Zn) occurred faster WH, differences starting 1 values, while fewer changes. Based content, recommend optimal conditions HTC studies preserve properties. Finally, discussed applications hydrochars, showing stability, especially − 18 °C, making it suitable various Graphical
