Characterization and reactivity of soot from fast pyrolysis of lignocellulosic compounds and monolignols
Trubetskaya, Anna; Brown, Avery; Tompsett, Geoffrey A.; Timko, Michael T.; Kling, Jens; Broström, Markus; Andersen, Mogens Larsen; Umeki, Kentaro (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 ... -
The effect of feedstock origin and temperature on the structure and reactivity of char from pyrolysis at 1300 2800 °C
Surup, Gerrit Ralf; Foppe, Manuel; Schubert, Daniel; Deike, Rüdiger; Heidelmann, Markus; Timko, Michael T.; Trubetskaya, Anna (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 ... -
Prediction of fast pyrolysis products yields using lignocellulosic compounds and ash contents
Trubetskaya, Anna; Timko, Michael T.; Umeki, Kentaro (Elsevier, 2019-10-26)The effects of lignocellulosic biomass composition on product yields and distributions were studied under high-temperature pyrolysis conditions (800–1250 C) in a drop tube reactor. Several types of biomass were studied ...
