Techniques for extracting organic sulfur and nitrogen compounds from coal without significantly altering the remainder of the coal matrix were tested in the laboratory. The concept for chemical removal of organic sulfur and nitrogen is feasible. Weak organic acids remove 45-80% of the organic sulfur from the coals investigated depending on process conditions and the specific coal leached. Nitrobenzene appears to be the most efficient solvent for the removal of organic sulfur. Aqueous caustic removes small amounts of organic sulfur from some coals, but none from others. Particle size (-200 mesh to 1/2-inch) has no discernable effect on the removal of organic sulfur by nitrobenzene. The leaching solvent, nitrobenzene, may be recycled at least three times to remove organic sulfur from coal. Weak organic acids and strong inorganic acids appear to remove nitrogen from the coals tested in this program according to the Dumas analytical method, but no nitrogen is removed according to the Kjeldahl method. Weak organic acids for removal of organic sulfur from coal may be readily adapted to engineering process schemes. The cost of the process for removal of organic sulfur from coal is highly dependent on the degree of solvent loss, and the ability to recycle solvent and allow high sulfur compound buildup. The process cost for removal or organic sulfur is approximately $1.00-$1.50/ton of coal. (Author)
