| 摘要 |
A process for hydrotreating carbonaceous materials is disclosed in which the carbonaceous material is contacted with steam and with empirical hydrates of alkali metal hydrosulfides, monosulfides, or polysulfides to hydrocrack, hydrogenate, denitrogenate, demetallize and/or desulfurize the carbonaceous material, hydrogen sulfide optionally being co-fed to the reaction zone. |
