Reactivity of heteroatom-containing organics during liquefaction of subbituminous coal: Quarterly technical progress report, March 15, 1988-June 15, 1988

Technical Report ·
OSTI ID:6918413
Deuteration of AO4 liquefaction solvent to an isotopic purity of approximately 99% was accomplished using a teflon-lined Parr bomb reactor. Tubing bomb liquefaction tests were performed using two sets of reaction conditions including coal and AO4, and coal and deuterated AO4. The THF insolubles to be used in testing the stability of the deuterated AO4 under liquefaction conditions were extracted using a Soxhlet apparatus and methylene chloride solvent. A system enabling product slurry distillation directly from the tubing bomb following completion of the liquefaction reaction was designed, constructed, and utilized to recover and quantitate volatile fractions of product slurries. The AO4 solvent was also distilled using the same equipment and procedure. Weighed amounts of eight deuterium-labeled species were added to weighed amounts of both labeled and non-labeled AO4 in preparation for the four remaining tubing bomb tests. 3 figs.
