Superhydrophobic and superlipophilic biochar produced from microalga torrefaction and modification for upgrading fuel properties

Biochar, Journal Year: 2023, Volume and Issue: 5(1)

Published: March 27, 2023

Abstract Torrefaction operation is an essential pathway for solid biofuel upgrading, and good hydrophobicity of torrefied biochar conducive to its storage. Herein, a two-stage treatment torrefaction followed by modification hexadecyltrimethoxysilane was adopted improve the moisture resistance performance biochar. This process led longer microalgal preservation time (60–200% improved) great superhydrophobicity superlipophilicity. Therefore, modified could significantly adsorb leaking oil environmental remediation further calorific value The obtained results indicated that adsorption capacity correlated temperature species. Specifically, enhanced up 70–80% from when comparing raw microalga. Increasing quantity By adsorbing oil, oilchar, namely, with adsorbed be higher than 40 MJ kg − 1 . Furthermore, pyrolysis combustion characteristics suggested stability gradually rose as increased. comprehensively analyzing fuel previous literature, possessed better properties sustainability.

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.
