Pyrolysis bio-oil is a liquid product of the pyrolysis of biomass. After appropriate upgrading, it
can be used as biofuel or as a source of valuable chemicals. To optimize a pyrolysis
process, a detailed understanding of the chemical composition of bio-oils is necessary.
Nonvolatile and high-molecular-weight bio-oil components have usually been analyzed by
Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometers that provide the
greatest mass resolution and mass accuracy among all currently available high-resolution …
