“…21,25,26 The band near 895/cm in the FTIR spectrum of hemicellulose sample can be used as a specific absorption band of hemicellulose, corresponding to the C O C bending vibration in hemicellulose. 38,39 Comparison with untreated straw biomass, the specific absorption bands of lignin (near 1710/cm and 1515/cm) in the FTIR spectrum of the Fe-HP pretreated straw were evidently reduced (Fig. 2; Table S4 and Table S5 in Supporting information).…”

“…Unlike the FTIR absorption spectra of cellulose and hemicellulose, the lignin sample displayed two specific absorption bands around 1710/cm and 1515/cm, corresponding to the stretching vibration of C O bonds and stretching vibration of C C stretching in lignin, respectively. 21,[37][38][39] The absorption band near 1430/cm in the FTIR spectrum of cellulose sample can serve as the specific absorption band of cellulose, corresponding to the CH 2 symmetric bending vibration in D-glucose unit of cellulose. 21,25,26 The band near 895/cm in the FTIR spectrum of hemicellulose sample can be used as a specific absorption band of hemicellulose, corresponding to the C O C bending vibration in hemicellulose.…”

BACKGROUNDThe development of efficient and green pretreatment pathway is of great significance for promoting biofuel production from lignocellulosic waste. The purpose of this work was to evaluate that iron ion‐catalyzed hydrogen peroxide pretreatment can be used as an environmentally friendly pretreatment way for bio‐jet fuel production using straw.RESULTSThe effects of iron ion‐catalyzed hydrogen peroxide pretreatment (Fe‐HP) on the enzymatic hydrolysis, fermentation and bio‐jet fuel production using straw were investigated. It was found that the iron ion‐catalyzed hydrogen peroxide pretreatment significantly improved the enzymatic hydrolysis and fermentation efficiency of straw biomass. Subsequently, the directional catalytic transformation of straw‐derived fermentation broth to bio‐jet fuels was achieved using a dual functional catalyst (HSAPO34/NiHBET). High conversion (94.9%) and good jet‐fuel selectivity (77.3%) were obtained in the conversion process of straw. On account of the biomass characterization and the analysis of reactive oxygen species during the Fe‐HP pretreatment, the role and mechanism of the Fe‐HP pretreatment was addressed.CONCLUSIONThe Fe‐HP pretreatment can be used as an environmentally friendly pretreatment way for jet fuel production from straw biomass. Fe‐HP pretreatment increased sugar yield and sugar concentration during enzymatic hydrolysis, which was beneficial for subsequent fermentation and bio‐jet fuel production. The reactive oxygen species take a prominent role in the Fe‐HP pretreatment of lignocellulose. © 2024 Society of Chemical Industry (SCI).

“…This is indicative of the viability of the selected additives as promoters of the ANFO decomposition. Among the investigated additives, SPB appears to be the most promising, as it offers the lowest effective pseudoactivation energy for ANFO decomposition, is a chlorine-free agent, and is often considered to be a "green" oxidising agent [24,25].…”

Towards “Green” ANFO: Study of Perchlorates and Inorganic Peroxides as Potential Additives

Ammonium nitrate–fuel oil (ANFO) explosives are inexpensive and readily produced, but are highly prone to misfires, with the remaining explosive being a significant risk and environmental contaminant. In this work, studies on various additives, such as selected perchlorates and inorganic peroxides, which are intended to lower the susceptibility of ANFO to misfires by increasing its sensitivity to shock, have been conducted. These studies showed the viability of using these additives in ANFO, allowing for conducting shock wave sensitivity tests for bulk charges in the future. We investigated the effects of introducing these additives into ANFO (on its sensitivity), as well as thermal and energetic properties. We observed minor increases in friction and impact sensitivity, as well as a moderate reduction in the decomposition temperature of the additive-supplemented ANFO in comparison to unmodified ANFO.
