Pyrolytic conversion of construction, renovation, and demolition (CRD) wood wastes in Québec to biochar: Production, characterization, and identifying relevant stability indices for carbon sequestration

The Science of The Total Environment, Год журнала: 2025, Номер 965, С. 178650 - 178650

Management of heterogeneous construction, renovation, and demolition (CRD) wood residues in Québec brings into light, a widespread topic under discussion related to their current disposal methods landfills, that may lead environmental concerns. With rising forfeitures from legal standpoint, alternative treatment for CRD wastes are being explored. Thermochemical biomass conversion techniques can be employed depolymerize low-quality end-of-life valorize it bio-based products. Biochar, carbonaceous material obtained through heat the absence oxygen via slow pyrolysis, tailored specific end-use applications hard-to-abate industrial sectors pertinent energy, composite materials, amendments. However, there is scarcity comprehensively understanding pyrolysis projecting biochar product's stability due lack relevant studies frequent inconsistencies amidst currently available methods. Nevertheless, present study, pyrolyzed horizontal tube furnace two scales laboratory conditions. Temperatures ranging 300 800 °C, residence time (BRT) 30-120 min, heating rates 20-55 °C/min, mass feedstock between 100 500 g were operational conditions chosen experimentation. Evaluation was carried out by proximate ultimate analysis, Van-Krevelen plots, TGA/DTG profile, R50 recalcitrance, SEM-EDX, Raman ID/IG Data analysis indicated carbon content (89-90 %), FC (70-74 TSF (73-75 (0.64-0.65), (0.972) increased with an increase BRT (120 min) temperature (800 °C) rendering its utilization metallurgical as reductant. A surface area 220-270 m2/g also detected these at °C recommending implementation adsorption applications. Biochar's cation exchange capacity (CEC), pH, hydrophobicity high temperatures nurturing ability used soil pH adjustment part remediation activities. SEM-EDX proved ash predominantly harboring alkaline earth metals (AAEM) like Ca K but certain point where devolatilization implicit, thereby concentrating stable carbon. As functionalities biochar, they decreased verifying rejection oxychemicals groups. Noticeable striations associated C-H/C-O/C=O vibration, stretching, bending FTIR spectral bands linked terminal dehydrogenation, condensation, aromatization reactions highlighting development CC linkages commonly assigned aromatics. Evident low H/C (0.51-0.09) O/C (0.08-0.02) indices, extrapolated high-temperature biochars PR:1 PR:2 possess permeance could bolster sequestration/draw-down other CDR

The Influence of Pyrolysis Temperature and Feedstocks on the Characteristics of Biochar-Derived Dissolved Organic Matter: A Systematic Assessment

Clean Technologies, Год журнала: 2024, Номер 6(3), С. 1314 - 1325

Опубликована: Сен. 19, 2024

Biochar is a carbon-rich product obtained by pyrolyzing biomass under oxygen-limited conditions and has wide range of potential for environmental applications. In particular, dissolved organic matter (DOM) released from biochar an important impact on the fate pollutants. The study aimed to systematically assess how varying pyrolysis temperatures feedstocks influence characteristics biochar-derived DOM. DOM samples were comprehensively characterized utilizing UV-vis spectroscopy excitation–emission matrix (EEM) fluorescence spectroscopy, coupled with parallel factor (PARAFAC) analysis. discovered that temperature significantly affects more than feedstock type. An increase in correlated notable decrease carbon content, aromaticity, intensity, alongside marked pH hydrophilicity. PARAFAC analysis identified three distinct components: two humic-like substances (C1 C2) one protein-like substance (C3). proportion increased higher temperatures, while substances’ declined. compositional shifts may its behavior functionality. Further research necessary explore long-term applications
