| Résumé: | In an attempt to develop alternative process that meet the prescribed levelsand green-technology criteria in gas-oil refining, N,N-methylpyrrolidone(NMP), dimethylformamide (DMF) mixed solvents under microwave-radiations (MW) were tested for the gas-oil desulfurization (EDS), denitrifica-tion (EDN) and dearomatization (EDA). In optimal conditions the gas-oilEDS-efficiency via MW can reach as high as 99.1% within 5 min at 500W inthree stages, which is much higher than EDS without MW (88.5% within15 min) or than those of ionic liquids. The NMP/DMF/EG can be reused formulti-cycles before being regenerated by adsorption method. This study willprovide useful information for future industrial application |
