Özet:
The feasibility of Raman Spectroscopy in the study of hydrodeoxygenation (HDO) reaction of pyrolysis oil model compounds was investigated. Hydroxyacetone, 4-n-Propylphenol, glycolaldehyde diethyl acetal, 1,6 anhydro-beta-D-glucopyranose, and 1,6 anhydro-beta-D-cellobiose were chosen as the model compounds to represent pyrolysis oil. The HDO reaction was simulated by analyzing multiple samples of varying concentrations of the reactants, and their corresponding HDO products. Gaussian Deconvolution algorithm was used to analyze the obtained Raman spectra, in order to identify, and differentiate between different peaks. The height of their respective characteristic stretching modes were then measured to determine the conversion of the model compound. The carbonyl (&ngr;C=O) stretching mode in hydroxyacetone, for instance, was found at 1,721 cm-1, (&ngr;CCO) sym. stretching mode of the acetal group found in glycolaldehyde diethyl acetal was observed at 1,140 cm-1 and the phenol (&ngr;C-O) stretching mode of 4-n-propylphenol was obtained at 1,204 cm -1, respectively. A calibration curve was then obtained from the corresponding peak height versus concentration. Insofar, in situ Raman could be used to measure the conversion of the hydrodeoxygenation of pyrolysis oil compounds.
