Characterization of free radicals by electron spin resonance spectroscopy in biochars from pyrolysis at high heating rates and at high temperatures
Trubetskaya, Anna; Jensen, Peter Arendt; Jensen, Anker Degn; Glarborg, Peter; Larsen, Flemming Hofmann; Andersen, Mogens Larsen (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 ... -
Comparison of high temperature chars of wheat straw and rice husk with respect to chemistry, morphology and reactivity
Trubetskaya, Anna; Jensen, Peter Arendt; Jensen, Anker Degn; Steibel, Markus; Spliethoff, Hartmut; Glarborg, Peter; Larsen, Flemming Hofmann (Elsevier, 2016-03-02)Fast pyrolysis of wheat straw and rice husk was carried out in an entrained flow reactor at high-temperatures (1000–1500) °C. The collected char was analyzed using X-ray diffractometry, N2-adsorption, scanning electron ... -
Potassium and soot interaction in fast biomass pyrolysis at high temperatures
Trubetskaya, Anna; Larsen, Flemming Hofmann; Shchukarev, Andrey; Ståhl, Kenny; Umeki, Kentaro (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 ...
