Direct biomass usage as a renewable fuel source and substitute for fossil fuels is discouraging due to high moisture, low energy density bulk density. Herein, thermogravimetric analysis (TGA) was conducted at various heating rates determine peak decomposition temperatures the dried cassava peels (DCP). The influence of pyrolysis temperature (300, 400, 500 600 °C) (10, 20 30 °C/min) on nickel nanoparticles catalyzed DCP produce biochar, bio-oil biogas investigated characterized. results revealed higher biochar (CBC) yield 68.59 wt%, 62.55 wt% 56.92 lower 300 °C different 10, °C/min. carbon content 52.39, 53.30 55.44 obtained elevated °C/min, respectively. At optimum (24.35, 17.69 18.16 wt%) (31.35, 42.03 46.12 were attained. A value (HHV) 28.70 MJ/kg °C. Through TGA, FTIR HRSEM results, thermal stability, hydrophobicity structural changes CBC samples established. Similarly, stability increased with increasing temperature.

Biochar yield prediction using response surface methodology: effect of fixed carbon and pyrolysis operating conditions

Biomass Conversion and Biorefinery, Journal Year: 2023, Volume and Issue: 14(22), P. 28879 - 28892

Published: Feb. 10, 2023

Abstract Generating value from wastes via pyrolysis has been increasingly researched in recent times. Biochar is a versatile product with yields based on many process parameters, including feedstock type and particle size, operating conditions such as reactor, heating rate, residence time, reaction temperature. The heterogeneous nature of waste biomass creates challenges controlling the pyrolysis’ selectivity. Intensive time-consuming experimental studies are often required to determine distribution for each unique feedstock. Alternatively, prediction models that learn wide range existing data may provide insight into potential different sources. Several advanced exist literature which can predict yield biochar subsequent products However, these do not consider combined effect characteristics yield, considered decisive factor formation. As such, objective this study develop model biomass’ fixed carbon content (14–22%), temperature (350–750 °C), rate (5–10 °C/min) using response surface methodology. Biomasses, date stones, spent coffee grounds, cow manure have used design Box-Behnken experiment three factors response. An empirical equation developed statistically significant quadratic produce optimized high accuracy. discussed 3D diagnostic plots conducted validation experiments confirm applicability model. significantly affected by temperature, confirms accuracy quantification. be easily applied further flow modeling pyrolysis, only relying proximate feed analysis, rate.

Published: March 4, 2025

Assessing the binder performance of thermal characterization is critical for quality control. This pertinent recovered binders from mixtures, which may not be in adequate quantities to evaluate their performance, particularly mixtures containing reclaimed asphalt pavement (RAP). The present study deployed a thermogravimetric analyzer compositional changes RAP-containing focusing on thermograph and derivative (DTG) characteristics correlating results rheological features. Incorporating RAP influenced binders’ DTG shapes, reducing low-combusted components (%LCC) increasing residues (%R). zero-RAP-containing mixture showed 4.36% increase %LCC 1.97% decrease %R compared short-term aged original binder. Binders exhibited greater stiffness than binders. dropped 7.22% 25.52%, while increased 20.69% 33.06%. Uncertainty analyses that area had least uncertainty uncertainty. Analysis through regression revealed can predict G*/sinδ well, showing correlation between better stability stiffness. research puts number properties, helps improve control
