- W122397568 abstract "Effort was concentrated on the study of coal rank dependence of H/sub 2/S-promoted liquefaction. Hydrogenation experiments were carried out on two lignites, two subbituminous, Absaloka, and two bituminous coals, at temperature 420/sup 0/C for 1 hr in the 12-mL tubing reactors constructed of 316 stainless steel. The reactors were charged by coal = 1.0 g; diphydrophenanthrene (DHP) = 1.0 g and by gases: H/sub 2/S, CO and H/sub 2/ (250:500:500 psi, respectively). The conversion to total volatile products was favored by the presence of H/sub 2/S for every coal. The average increase of yield of volatiles attributed to H/sub 2/S is 5.85%. The increase in yield appeared principally in the heavy oils. However, the technique used to trap the light oils in these experiments led to considerable loss into the gas fraction. The conversion as measured by tetrahydrofuran solubility did not reveal any significant change in yields for the two conditions used. These yields are uniformly high and imply there is a residue within coal which will not convert into a soluble form by either of these conditions. Dihydrophenanthrene is an excellent hydrogen donating molecule. Yet H/sub 2/S is still able to augment its ability to convert coal into volatilemore » products. Since it is unlikely H/sub 2/S can compete with dihydrophenanthrene as a hydrogen donor, H/sub 2/S must be promoting the conversion via another mechanism. when the dihydrophenanthrene to coal ratio is increased, the conversion also increases. 11 references, 2 tables.« less" @default.
