This study investigates the intricate thermal decomposition behavior and combustion characteristics of two distinct types wheat straw pellets (WSP) represented as T1 (100% straw) T5 (70% straw; 10% sawdust, biochar; bentonite clay). Through a thermogravimetric analyzer (TGA) undergo under varying heating rates (5, 10, 20°C/min) in an air atmosphere, ranging from 25 to 1200°C. Differential analyses reveal four stages biomass components. The results indicate that optimal rate is 20°C/min, resulting highest reaction (∼50%/min) most substantial mass loss (∼55%) for both pellets. Notably, pellet demonstrates lower ignition temperature (207°C, at higher burnout (457°C 10°C/min) compared pellet, indicating its superior suitability combustion. efficiency ranges 61.0 99% within range 300 700°C, similar coal Additionally, thermodynamic properties (Di, Db, C, S) suggest promising potential WSP bioenergy feedstock. Furthermore, demonstrate temperatures (Ti) than T5, indicative rapid energy potential. (Tb) revealed scenarios. These findings hold significance design gasification or reactors industrial utilization biomass. insights gathered this offer valuable guidance designing enhancing systems fostering sustainable practices utilizing agricultural residues production.

Thermo-catalytic pyrolysis of sewage sludge and techno-economic analysis: The effect of synthetic zeolites and natural sourced catalysts

Bioresource Technology, Год журнала: 2024, Номер 400, С. 130676 - 130676

Опубликована: Апрель 7, 2024

This work focuses to the value added utilization of animal sewage sludge into gases, bio-oil and char using synthetic zeolite (ZSM-5 Y-zeolite) natural sourced (diatomite, kaolin, perlite) materials as catalysts. Pyrolysis was performed in a one-stage bench-scale reactor at temperatures 400 600 °C. The catalyst mixed with raw material before pyrolysis. Catalysts had significant effect on yield products, because amount volatile products higher their presence, than without them. In case due structural transformation occurring between 500–600 °C, increase activity observed terms pyrolysis reactions resulting volatiles. hydrogen content gas increased significantly temperature °C thermo-catalysts presence catalysts, more favourable properties.

Bioenergy is anticipated to play a significant role in the United Kingdom's Net Zero 2050 scenario. This study aims explore possibility of producing hydrogen-rich syngas using sewage sludge from Howden wastewater treatment plant located Newcastle, Kingdom. The primary objective this experimentally produce through pre-treatment, drying, and pyrolysis. Furthermore, statistical methods have been employed optimise performance pyrolyser. individual desirability scores for lower heating value (LHV) cold gas efficiency (CGE) were estimated be 0.83902 0.85307, respectively. Combining these scores, overall model reached 0.8460, indicating favourable predictive performance. optimal operational conditions are reported feed rate 3.0488 revolutions per minute (rpm) an temperature 800°C. Under conditions, highest calculated CGE 66.31% peak LHV 18.36 MJ/ m^3 achieved.

Unveiling the microwave heating performance of biochar as microwave absorber for microwave-assisted pyrolysis technology

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Апрель 22, 2024

Abstract Microwave (MW) heating has gained significant attention in food industries and biomass-to-biofuels through pyrolysis over conventional heating. However, constraints for promoting MW related to the use of different absorbers are still a major concern that needs be investigated. The present study was conducted explore performance biochar as low-cost absorber performing pyrolysis. Experiments were performed on under dosing (25 g, 37.5 50 g), power (400 W, 700 1000 W), particle sizes (6 mm, 8 10 mm). Results showed significantly impacted average rate (AHR) from 17.5 65.4 °C/min at 400 W g. AHR first increased, then no changes obtained, examined by full factorial design, with 94.6% fitting actual data predicted data. model suggested size influenced less AHR. Furthermore, microwave absorption efficiency weight loss investigated, decreased which means 17.16% achieved rather than W. Biochar estimated employing mass-balance analysis, 2–10.4% change obtained owing higher rates powers dosing.
