Hydrogenation of Ethanol-Solubilized Coals over a Ru/Al2O3 Catalyst and Their Pyrolysis Reactivities |
| 초록 |
Coals were subjected to mild oxidation in an aqueous solution of H2O2 in the presence of n-propanol. The ethanol-soluble fractions were hydrogenated over a Ru/Al2O3 catalyst, yellowish white solids (hereafter, referred to as hydrogenated white coals [1]) were obtained after solvent removal. Aromatic rings and side chains were hydrogenated, and some of the sp2 carbon bondings were changed into the sp3 structure. Pyrolysis reactivity was improved by oxidation and hydrogenation and correlated well with the H/C and O/C atomic ratios in the raw, oxidized and hydrogenated coals.
