Thermogravimetric and Pyrolysis-Capillary Gas Chromatography-Mass Spectrometric Analysis of Pinus Halepensis Mill. Wood

Abstract EN

The analytical methods TG and Py-capillary-GC-MS were used to study the thermal degradation of Pinus halepensis Mill.

Wood.

The TG analysis in air and in nitrogen showed that the percentage content of char and ash were, 23.1 % and 7.7 % respectively.

TG and DTG analysis proved that the evolution of organic degradation products occurs mainly between 215 °C and 380°C and has its maximum evolution rate at 360°C in nitrogen and 347°C in air.

Py-capillary-GC-MS analysis of the pyrolysis at 400 °C identified the presence of valuable chemicals such as aliphatic and aromatic hydrocarbons, phenols, aldehydes, esters, and saturated and unsaturated long chain fatty acids.
