The effect of feedstock origin and temperature on the structure and reactivity of char from pyrolysis at 1300 2800 °C
(Elsevier, 2018-07-31)
This study reports the effect of feedstock origin, residence time, and heat treatment temperature on CO2 and O2 reactivities, nanostructure and carbon chemistry of chars prepared at 1300, 1600, 2400, and 2800 °C in a slow ...
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 ...
Characterization of renewable reductants and charcoal-based pellets for the use in ferroalloy industries
(Elsevier, 2018-11-05)
This study investigates the effect of high-temperature pyrolysis and post-treatment processes on spruce and oak charcoal yields and CO2 reactivity in a slow pyrolysis reactor. Post-treatment processes such as co-pyrolysis ...
Characterization and reactivity of soot from fast pyrolysis of lignocellulosic compounds and monolignols
(Elsevier, 2018-02-06)
This study presents the effect of lignocellulosic compounds and monolignols on the yield, nanostructure and reactivity of soot generated at 1250 C in a drop tube furnace. The structure of soot was characterized by electron ...
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 ...
Removal of phenol and chlorine from wastewater using steam activated biomass soot and tire carbon black
(Elsevier, 2018-10-30)
This study aims to demonstrate a novel method for removing toxic chemicals using soot produced from wood and herbaceous biomass pyrolyzed in a drop tube reactor and tire pyrolytic carbon black. The influence of ash content, ...
Characterization and reactivity of charcoal from high temperature pyrolysis (800–1600 °C)
(Elsevier, 2018-09-22)
This study presents the effect of wood origin and heat treatment temperature on the CO2 reactivity, nanostructure and carbon chemistry of chars prepared at 800, 1200, and 1600 °C in slow pyrolysis reactors. The ...
