Title: Advanced coal liquefaction research. Technical progress report, January 1-April 30, 1984

Abstract

The significant improvement in product quality reported last year for bituminous and subbituminous coals has been demonstrated with lignite. As discussed previously, use of a vapor-phase hydrotreater and recycle of all heavy distillate advances the SRC II process far beyond that envisioned for the original demonstration plant. As with the other coal ranks, all net distillate product from the lignite boils below 345/sup 0/C (653/sup 0/F) and has a nitrogen concentration on the order of 1 ppM. It was also confirmed that the Texas Big Brown lignite can be processed successfully in this mode without added catalyst. Both subbituminous Belle Ayr and bituminous Illinois No. 6 coals were processed in an integrated two-stage mode, without depressurization or solids separation between stages. Operation was relatively smooth with a fixed-bed second stage employing a high-void-volume (star-shaped) catalyst support, which was operated upflow. There was no evidence that H/sub 2/S addition improved yields with Belle Ayr coal and added pyrite or that H/sub 2/S could be used in place of pyrite to catalyze the reaction. 84 figures, 6 tables.
