- Advances in the organic desulfurization of coals and resids depend upon the discovery of methods for the secure definition of the sulfur forms in fossil fuel materials as well as upon the discovery of innovative chemical desulfurization strategies. This report deals with the coupling of selective chemical methods with XANES in an investigation of the desulfurization of Illinois No. 6 bituminous coal and Rasa subbituminous coal. The Argonne National Laboratory Premium sample of Illinois No. 6 bituminous coal and a sample of Rasa subbituminous coal that was provided by Ljiljana Ruscic were used in these experiments. TheIllinois No. 6 coal contains 81%C (maf) with 2.0%S in organic compounds and 2.8%S in pyrite. The Rasa coal contains 73%C (maf) with 11.7%S in organic compounds. The procedures that we used for selective desulfurization with lithium aluminum hydride (1-3), potassium naphthalene ([minus]l), (3), and n-butyllithiumpotassium 1-butoxide (4) have been described previously. Conventional isolation procedures were used in most experiments, however, the facility with which some of the residual sulfur-containing compounds underwent air oxidation prompted us to protect the reaction products from oxygen in certain experiments.
