Simulation and Thermodynamic Evaluation of Woody Biomass Waste Torrefaction

ACS Omega, Journal Year: 2025, Volume and Issue: 10(4), P. 3585 - 3597

Published: Jan. 21, 2025

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.

Thermochemical treatment of spent coffee grounds via torrefaction: A statistical evidence of biochar properties similarity between inert and oxidative conditions

Results in Engineering, Journal Year: 2024, Volume and Issue: 21, P. 102012 - 102012

Published: March 1, 2024

This study used several statistical analyses to explore the impact of both inert and oxidative conditions on characteristics biochar derived from torrefaction spent coffee grounds (SCG). The also considered variations in temperature residence time. Various fuel were conducted, including high heating value (HHV), index, proximate characteristics, thermogravimetric analysis (TGA), hygroscopicity, Fourier-transform infrared spectroscopy (FTIR). variance (ANOVA) revealed that influence HHV mass yield was insignificant (p ≥ 0.05). Moreover, considering same time, principal component (PCA) hierarchical cluster (HCA) identified belonging group or cluster. finding indicated neither atmospheric condition significantly affected measured this research. Therefore, offers significant advantages as it can produce comparable quality under conditions.

The significance of structural components of lignocellulosic biomass on volatile organic compounds presence on biochar - a review

Wood Science and Technology, Journal Year: 2024, Volume and Issue: 58(3), P. 859 - 886

Published: May 1, 2024

Abstract The product of thermochemical processing lignocellulosic biomass is biochar. It has a range properties that make it suitable for variety economic applications. However, during pyrolysis and torrefaction, volatile organic compounds (VOCs) are released may redeposit on the surface Some these be harmful to environment humans. Bibliometric study shows that, date, studies release VOCs from biochar have been an inventory nature concerned with specific case types biomass. To there no comprehensive systematic analysis influence pyrolysis/torrefaction process parameters VOC formation redeposition In this paper, presented potential harmfulness components, based cellulose, hemicellulose, lignin chemistry data. 10 were identified as potentially due following properties: carcinogenicity, toxicity, flammability, skin corrosion/irritation, eye irritation, mutagenicity, different degrees harmfulness. Additionally, samples show hazard. Among 140 compounds, 33 them had properties. Therefore, ketones, aldehydes, cyclic aromatic hydrocarbons including polyaromatic hydrocarbons, their derivatives, esters, furans lead environmental contamination A new niche research development knowledge regarding biochars produced source pollutant emission identified.
