The objective of the described work is to provide a greater understanding of the role of heteroatoms in coal reactivity during low-severity liquefaction. The tasks performed in this report period focused mainly on reaction engineering. Products from the reactions will be extensively analyzed during the following report period. An autoclave liquefaction run was made to produce insoluble organic material (IOM) from Clovis Point coal for use in evaluating the stability of deuterium-labeled A04 solvent under liquefaction conditions. Based on the results of duplicate tubing bomb tests, the isotopic purity of the deuterium-labeled A04 appears to be stable under mild (350/sup 0/C) conditions. Three other reaction conditions were tested during the same tubing bomb run. Test 2 was a reaction with coal and deuterium-labeled A04 solvent, test 3 was a reaction using A04 spiked with a set of 17 deuterium-laveled compounds, and test 4 used A04 spiked with 3 deuterium-labeled hydrogen donor species. All tests were duplicated, none of the 8 tubing bombs leaked, and all gave good recoveries.
