Since all the nitrogen compounds that have been identified in coal-derived liquids in the past have been basic in character, the effect of an acid-wash on the nitrogen content of coal-derived liquids was examined. Because sulfuric acid is the cheapest of the commerical strong acids, it was the natural choice, and its use was examined in detail. The greater the concentration of the sulfuric acid used, the greater the amount of nitrogen removed. :he sulfur compounds in coal-derived liquids were not removed noticeably by extraction with sulfuric acid. Column chromatography is a possible technique for removal of nitrogen compounds. The sulfur content was not changed by the column chromatography method. Although the sources of coal were different, they were found to respond to both acid extraction and column chromatography.
