One way of representing the size and shape of biomass particles in combustion modeling
(Elsevier, 2017-06-29)
This study aims to provide a geometrical description of biomass particles that can be used in combustion models. The particle size of wood and herbaceous biomass was compared using light microscope, 2D dynamic imaging, ...
Characterization of free radicals by electron spin resonance spectroscopy in biochars from pyrolysis at high heating rates and at high temperatures
(Elsevier, 2016-09-06)
The concentration and type of free radicals from the decay (termination stage) of pyrolysis at slow and fast heating rates and at high temperatures (above 1000°C) in biomass char have been studied. A room-temperature ...
The nature of stable char radicals: An ESR and DFT study of structural and hydrogen bonding requirements
(Wiley, 2018-06-28)
Pyrolysis is a promising way to convert biomass into fuels and chemicals. This reaction is complex and inevitably involves a cascade of radical reactions that lead to char formation, in which some radicals become trapped ...
Potassium and soot interaction in fast biomass pyrolysis at high temperatures
(Elsevier, 2018-04-02)
This study aims to investigate the interaction between potassium and carbonaceous matrix of soot produced from wood and herbaceous biomass pyrolysis at high heating rates at 1250°C in a drop tube reactor. The influence of ...
