Torrefaction is a thermochemical pretreatment that enhances biomass properties, improving energy density, decomposition resistance, and hydrophobicity, making it viable alternative as biofuel. This study performed thermodynamic assessment of the torrefaction process for urban forest waste, integrating experimental data with two-step reaction kinetic modeling to evaluate product yields properties using Aspen Plus software. The was modeled yield reactor, employing Peng–Robinson equation describe vapor-phase behavior empirical correlations predict solid-phase properties. Simulations were validated against temperatures between 225 275 °C, achieving an absolute deviation less than 5%. Energy consumption ranged from 368 kJ·h–1 light 1853 severe torrefaction. Process irreversibility varied 326 (3% exergy destruction) in 3993 (16% research provides robust model scale-up adaptable diverse feedstocks conditions, highlighting its potential optimizing use sustainability utilization.

The coconut tree (Cocos nucifera) stands as a pivotal resource in tropical regions, playing crucial role both subsistence and economic activities across Asia, the Pacific Islands, South America. While harvesting of fruit is essential for producing globally utilized edible products, such oil, by small owners large producers around world food, cosmetics, pharmaceutical industries, concerns have arisen due to substantial amount agro-industrial residue generated this process, posing environmental risks if they are not properly managed. Recognizing challenges, paper emphasizes transformative potential inherent waste, characterized its lignocellulosic composition rich lignin multifunctional groups. By delving into historical context exploration chemical composition, review explores diverse applications focusing on utilization processing residues generate sustainable products byproducts. Ultimately, comprehensive underscores significance repurposing only mitigate impact but also valuable contributor circular economy, promoting use biomass research bolstering raw material energy sectors.

In this study, we evaluated the effect of modification biochar on adsorption Cr(VI) under weakly acidic conditions. Sesame straw (BC) was modified by treatment with ferric chloride to produce iron-modified (FBC) and chlorapatite iron-doped chlorapatite-modified (FBCP). Analysis scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) showed that mechanism FBC FBCP reduction, physical adsorption, ion exchange, functional group complexation. Experiments were performed evaluate kinetic, isothermal, thermodynamic characteristics demonstrating a spontaneous endothermic reaction, consistent pseudo-second-order kinetic model Langmuir model, process dominated monolayer chemical adsorption. The revealed maximum saturated capacities for 7.907 12.625 mg/g FBCP, respectively, equating 4.06 6.48 times capacity BC, respectively. Compared FBC, phosphate ions in also co-precipitated Cr(III), further improving removal efficiency pollutants.

Abstract This study focuses on the utilization of agro‐residual corn‐cob biomass, waste plastic and combination both for pyrolysis reaction using thermal analysis. Circular bioeconomy is assured by closing all resource materials loops through co‐pyrolysis process. The conversion profiles corn cob at various heating rates reveal a three‐stage decomposition process, exhibits single stage degradation. Due to interaction between blended materials, additional degradation peaks arise during (PET bottles) biomass (corn cobs). apparent activation energy fluctuates in range 120–260 kJ/mol with conversion, according Flynn‐Wall‐Ozawa (FWO) Kissinger‐Akahira‐Sunose (KAS) kinetic methods. Notably, lower (168 FWO) than individual (179 (175 FWO), suggesting positive synergistic effect charring. liquid crude char product analysis from pyorlysis FTIR XRD confirms application products chemical processes. results obtained this can be utilized reactor specifically bottles that are accumulating environment.
