Development of quantitative ¹³C NMR characterization and simulation of C, H, and O content for pyrolysis oils based on ¹³C NMR analysis.

ABSTRACT: Bio-oil is a valuable liquid product obtained from pyrolysis of biomass and it contains tens of hundreds of compounds, which brings about difficulties for characterization with various analytical methods. ¹³C NMR has advantages over other detection methods as it can characterize the entire composition of bio-oil and distinguish different types of carbon. But various shortcomings limit the application of ¹³C NMR. This study was carried out to develop a quantitative ¹³C NMR method to determine different functional groups in pyrolysis bio-oils with short NMR time and good accuracy, and propose a simulation of C, H, and O content for pyrolysis oils based on ¹³C NMR analysis. In order to solve long-term NMR problems, relax reagent has been added and t
