Fast pyrolysis biofuel is considered as one of the promising alternative fuels for future transportation. The authors' research group has improved a pyrolysis biofuel production method for obtaining a biofuel from rice husk. Preliminary research published in Fuel reveals that it has the potential of being used as a gasoline blending component. Before this biofuel can be widely used in real combustors or engines at a large scale, its explosion characteristics should be investigated for the safety consideration during production, transport and storage. This paper quantitatively evaluates explosion pressure, deflagration index, maximum pressure rise rate and combustion duration of this biofuel in the constant volume combustion chamber (CVCC). At the same time, the effects of initial pressure, initial temperature and equivalence ratio on explosion characteristics of this biofuel was also qualitatively analyzed. Linear relationships between explosion pressure, deflagration index, maximum pressure rise rate and combustion duration versus initial pressure and explosion pressure versus initial temperature are given. Results show that explosion pressure is a linear relationship with the initial temperature. However, deflagration index, maximum pressure rise rate and combustion duration are insensitive to the temperature variation.

Massive injection of C depleted carbon to the ocean and atmosphere coincided with major environmental upheaval multiple times in the geological record. For several events, the source of carbon has been attributed to explosive venting of gas produced when magmatic sills intruded organic-rich sediment. The concept mostly derives from studies of a few ancient sedimentary basins with numerous hydrothermal vent complexes (HTVCs) where craters appear to have formed across large areas of the seafloor at the same time, but good examples remain rare in strata younger than the Early Eocene.

Xylooligosaccharides (XOS), short-chain polymers with prebiotic properties, have gained significant commercial attention over the past few decades due to their potential as nutraceutical components. Derived from lignocellulosic biomass (LCB), XOS serve as health promoting compounds with applications across multiple sectors, including food pharmaceutical and cosmetic. This comprehensive review provides an overview of XOS production, purification, characterization, and quantification, highlighting their derivation from various sources such as agricultural waste, agro-economical forest residues, and nutrient-dense energy crops.

The performance of energetic coordination compounds (ECCs) is influenced by their components and structure. Modifying the chemical structure of the ligands can balance the detonation performance and sensitivity. This study introduced Cu(3-PZCA)(ClO) () and Cu(2-IZCA)(ClO) (), using 3-PZCA and 2-IZCA as ligands.

The inhibition of methane-air explosions by air jet-driven NaHCO powders and porous barriers was investigated in this study. Flame images and overpressure data were recorded using high-speed cameras and pressure sensors. The inhibition mechanism of NaHCO powder was further investigated using the reaction mechanism of sodium-containing substances and methane combustion.
