Work performed under Task A is reported in two parts: Part 1 describes the promotion, by the addition of real coals, of the cleavage of strong bonds in model coal structures, as predicted by our previously proposed hydrogen-transfer/bond-cleavage mechanism; and Part 2 is an analysis that reconciles the reported slow isotopic exchange (C) between tetralin and naphthalene with accepted or proposed mechanisms of radical generation and hydrogen transfer in such systems. Efforts in Task B, Conversion in CO/H/sub 2/O Systems involved a study of the conversion characteristics of Eastern Province bituminous coals in CO/H/sub 2/O. All coals were subjected to identical reaction conditions of 400/sup 0/C/20 min in CO/H/sub 2/O at pH 13. The amount of CO that reacted was nearly identical in all runs, indicating that the extent of water-gas-shift reaction is independent of the coal used in the reaction. The amount of toluene-soluble material varied widely from 85% (dmmf) for an Ohio No. 9 coal to only 3% for a Pocahontas No. 3 coal.
