Abstract: | Characteristic diagrams, which are very useful in studies of the reaction pathways in coal liquefaction processes and to characterize coal-derived materials, are presented. Using model compounds, aromatic carbon fraction, fa, and aromatic proton fraction, faH, are plotted against atomic ratio. The experimental results of an anthracene oil and its hydrogenated oils are plotted on these diagrams, and the usage and the validity of the charts are verified. |
