Abstract The present investigation explores the efficacy of green algae Ulva lactuca biochar-sulfur (GABS) modified with H 2 SO 4 and NaHCO 3 in adsorbing methylene blue (MB) dye from aqueous solutions. impact solution pH, contact duration, GABS dosage, initial MB concentration on adsorption process are all methodically investigated this work. To obtain a thorough understanding dynamics, study makes use several kinetic models, including pseudo-first order pseudo-second addition to isotherm models like Langmuir, Freundlich, Tempkin, Dubinin–Radushkevich. findings reveal that capacity at equilibrium ( q e ) reaches 303.78 mg/g for dose 0.5 g/L an 200 mg/L. Notably, Langmuir model consistently fits experimental data across different doses, suggesting homogeneous onto monolayer surface. potential as efficient adsorbent extraction solutions is highlighted by discovery. study’s provides robust framework intricacies GABS. By elucidating various variables process, research contributes valuable insights can inform design wastewater treatment comprehensive analysis presented serves solid foundation further development field adsorption-based water technologies.

Computational Fluid Dynamics Simulation and Reaction Network Modelling for the Hydrothermal Liquefaction of Shorea Wood Sawdust

Energies, Год журнала: 2025, Номер 18(5), С. 1145 - 1145

This study investigates the hydrothermal liquefaction (HTL) aqueous phase (AP) of Shorea sawdust in a semi-flow batch reactor, focusing on reaction network and computational fluid dynamics (CFD) simulation. High-performance liquid chromatography (HPLC) was used to detect lignocellulosic decomposition compounds, revealing presence glucose, galactose, xylose, furfural, ethanol, other undefined compounds due decomposition. Reaction ordinate (R0) indicates that progresses steadily as time increases, higher temperature leads greater ordinate, agreeing with Arrhenius’ assumption gained energy enables molecules overcome activation barrier. However, saccharide C6 C5 yield at 220 °C fluctuates suggesting secondary reactions. A kinetic model built based network, which developed HPLC results. Arrhenius parameters revealed is influenced by time, whereas ethanol production are dependent. In contrast, glucose formation both temperature. The prediction yields confirmed optimal for production, balancing slow reactions rapid degradation. CFD simulations show uniform pressure distribution inside chamber high localised input (1570 Pa). addition, feedstock particles tend distribute along wall because laminar flow, consistent observation experiment. findings highlight intricate relationship between conditions composition HTL product, contributing more comprehensive understanding process.

Technical Approach for Transformation of Food Industry Waste to Optimising Hydrochar Via a Green Process: Productive, Structural and Environmental Perspective

Опубликована: Янв. 1, 2024

The present work aimed at optimizing the hydrothermal carbonization (HTC) of a global food industry waste to get an optimal hydrochar (PBHC) with superior fuel/energy and physicochemical characteristics by sustainable, eco-friendly low-cost process. HTC conditions, namely reaction temperature (RT) time (Rt), were optimized as function elementel carbon content (%C), higher heating value (HHV), energy densification (ED). Under operating conditions (RT:220 °C, Rt: 12 h feedstock/water mass ratio 1:10), PBHC %C 57.90, HHV 23.23 MJ/kg ED 1.22 GJ/m3 was obtained selected for further studies. Additionally, evaluate environmental performance, batch isotherm experiment conducted assess feasibility using toxic MB MO dye removal maximum uptake capacity 27.47 13.76 mg/g. In conclusion, can be used direct solid biofuel potential sorbent.

Cadmium pollution is a serious environmental issue that has an impact on both the ecosystem and human health. As result, its removal from water essential. Agro-industrial wastes are suggested as sustainable adsorbent option, they among most readily available renewable sources worldwide. Biochar carbonized biomass been shown to be viable novel adsorbent. This article compares results of cadmium adsorption biochars derived wood industry craft beer production wastes. Biochars were characterized before after adsorption. Batch 0.18 mmol/L Cd(II) concentration solutions indicated percentages (A%) 99.7% 92.2% for sawdust biochar barley biochar, respectively. For this concentration, presented capacity (qm) 0.0172 mmol/L, while value 0.0159 mmol/L. The influence initial single multimetal was studied, decrease in observed presence Ni(II) Zn(II). Freundlich isotherm model found best fit data isotherms biochars. According article, performance can safely disposed building bricks at end useful life.
