| Résumé : | Electroreduotion of coal is studied in aqueous tetrabutylammonium hydroxide (TBAOH) solution and tetrabutylammonium tetrafluoroborate (TBABF4) -THF-H2O solution by using platinum as anode and Hg pool as cathode. The electrolysis in aqueous TBAOH solution seems to have little effect on the following HyPy although the pyridine extractable yield of reduced coal increases. In an undivided cell the re-oxidation of the reduced coal occurs. Cathodic reduction in TBABF4-THF-H2O solution gives a pronounced effect on HyPy. Higher conversion (60.9%) and total oil yield (50.6%) (THF soluble + oil formed in HyPy) are obtained in a divided cell as compared with 42.1% and 28.4% for untreated coal, respectively. The electroreduction pretreatment of coal enhances the rate of oil formation and the oil yield in HyPy of the reduced coal, indicating that the reduced coal can be depolymerized more easily due to the solvolysis and hydrogenation. |
