Study on the thermal stability of the bio-oil components by Py-GC/MS

Energy Reports, 2023
Pyrolysis-gas chromatograph/mass spectrometry (Py-GC/MS) was used to study the thermal stability of the bio-oil components as the pyrolysis temperature increased from 100 °C to 550 °C. The peak area changes of 66 typical compounds identified by GC/MS are
