Laser-Powered Homogeneous Pyrolysis (LPHP) of Lignin Dispersed into Gas Phase [PDF]

open access: yesMolecules
The gas-phase delivery of lignin into the hot zone of cw-CO2 laser-powered homogeneous pyrolysis (LPHP) reactor under “wall-less” conditions led to the breakdown of lignin macromolecules into neutral oligomers and paramagnetic fragments deposited onto ...

Enhanced soot particle ice nucleation ability induced by aggregate compaction and densification [PDF]

open access: yesAtmospheric Chemistry and Physics, 2022
Soot particles, acting as ice nucleating particles (INPs), can contribute to cirrus cloud formation, which has an important influence on climate. Aviation activities emitting soot particles into the upper troposphere can potentially impact ice nucleation

Quantifying evolution of soot mixing state from transboundary transport of biomass burning emissions

open access: yesiScience, 2023
Summary: Incomplete combustion of fossil fuels and biomass burning emit large amounts of soot particles into the troposphere. The condensation process is considered to influence the size (Dp) and mixing state of soot particles, which affects their solar ...

Numerical Simulation of Particle-Laden Flow and Soot Layer Formation in Porous Filter

open access: yesSolids, 2022
So far, diesel particulate filters (DPFs) have been widely used to collect diesel particulates including soot in the exhaust after-treatment. However, as the soot is continuously collected in the porous filter, the exhaust pressure (pressure drop ...

Identification of Plant Soot as Novel Safe Feed Additive: Evaluation of 90-Day Oral Toxicity and Prenatal Developmental Toxicity in Rats

open access: yesFrontiers in Veterinary Science, 2020
Plant soot, as a novel feed additive, could not only improve digestive function but also adsorb mycotoxins and inhibit bacterial infections. The subchronic toxicity and prenatal developmental effects of plant soot were studied for the first time.

Conditional moment closure modelling of soot formation in turbulent, non-premixed methane and propane flames [PDF]

open access: yes, 2009
Presented are results obtained from the incorporation of a semi-empirical soot model into a first-order conditional moment closure (CMC) approach to modelling turbulent, non-premixed methane–air and propane–air flames.

Effects of dimethyl ether on soot formation in premixed laminar flame by laser induced incandescence method

open access: yesJournal of Traffic and Transportation Engineering (English ed. Online), 2020
The control of PM emission is a rather complicated problem to be solved both for diesel engine and GDI engines. There are vast factors affecting PM emission, the fuel, A/F, combustion temperature and so on.

On the Response of Nascent Soot Nanostructure and Oxidative Reactivity to Photoflash Exposure

open access: yesEnergies, 2017
Soot particles are a kind of major pollutant from fuel combustion. To enrich the understanding of soot, this work focuses on investigating detailed influences of instantaneous external irradiation (conventional photoflash exposure) on nanostructure as ...

Soot formation characteristics in hybrid pyrolysis of zero-carbon fuel ammonia and ethylene mixtures

open access: yesFrontiers in Energy Research, 2022
As soot particles from incomplete combustion of fossil fuels pose a great threat to human health, the development of low-carbon or zero-carbon alternative fuels is essential to mitigate climate change. An experimental and numerical study on the pyrolysis
