摘要: This chapter describes analytical chemical methods used to characterize high-mass materials found in liquids and tars from coal processing crude petroleum fractions such as asphaltenes the conversion of biomass into liquid fuels. Methods described include size exclusion chromatography with different solvents, mass spectrometric method including laser desorption, nuclear magnetic resonance, fractionation techniques, vapour pressure osmometry, UV-fluorescence Fourier Transform infrared spectroscopy. Significant developments these fields are described. Comparison ion cyclotron resonance spectrometry (FT-ICR-MS) reveals significant shortcomings that application residues. The components have previously been ignored.
