LIQUEFICATION OF SOLID CARBONACEOUS MATERIAL |
摘要 |
<p>A method is described to improve a coal liquefaction process by the use of a recycle solvent comprised of two fractions: the first, a lower boiling fraction, is obtained by an atmospheric distillation and is subsequently hydrotreated to enrich its hydrogen donor capacity; the second is a higher boiling fraction that is enriched in desirable hydrogen transfer agents by a solvent extraction process. The combined recycle solvent thus obtained is more efficient in transferring gas phase H2 to the coal and enables other significant process improvements.</p> |
