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...
