Recycling of used railroad ties via two-staged pyrolysis for fractionation of wood preservatives and bio-oil: pyrolytic characterization by TGA and Py-GC/MS
2015 - IRG/WP 15-50311
Creosote and copper naphthenate (CuNap) (in an oil carrier) treated railroad tie materials (crossties or sleepers) were initially heat-treated at 200 – 300 oC and subsequently pyrolyzed via thermogravimetric analysis (TGA) and pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) to recover wood preservatives and produce a higher quality bio-oil. Preservative-desorptive temperatures at 200 a...

Evaluation of decay and energy properties from thermally modified biomasses during fungal deterioration by NIR-spectrometry
2021 - IRG/WP 21-40922
This study is focused on the prediction of fungal weight loss (WL) and high heating value (HHV) from raw and torrefied waste lignocellulosic feedstocks, according to their exposure duration to wood-destroying fungi, using near infrared spectroscopy (NIR) and chemometrics models.
Sugarcane bagasse, coffee husk, eucalyptus and pine shavings were torrefied at 290 °C in a screw reactor, during 5, 7...
