EDS Coal-Liquefaction Process Development, Phase V: EDS Product Quality. Final Report

摘要

The laboratory product quality studies were conducted at various Exxon Research and Engineering (ER and E) facilities. This Final Product Quality Report summarizes research efforts directed at end-use applications of raw and upgraded EDS products. The end-use applications, including any upgrading by hydrotreatment required to ensure adequate performance, are identified for products derived from Illinois (Monterey mine) and Wyoming (Wyodak mine) coals. The results presented are intended to update and supplement information reported previously for these products in EDS Product Quality Interim Report, FE-2893-68, March 1981. The broad objectives of EDS product quality studies are to identify potential end-uses for coal-derived liquids and to evaluate properties of these liquids relative to requirements of these potential applications. Areas pertaining to product quality requiring further development are highlighted. Consideration of future market needs combined with generic properties of EDS-derived products may suggest a clean product slate (naphtha/distillate) as the most desirable, long-range EDS product objective. Properties of lighter EDS product streams (naphtha, distillates) are essentially independent of liquefaction operating conditions for a given coal. This applies to both coal-only and bottoms recycle operations. With the exception of heterocyclic content, primarily sulfur, properties of lighter EDS product streams (naphtha, distillates) are very nearly coal-independent. (ERA citation 08:001516)
