Removal of Nitrogen & Sulfur from Coal-Derived Liquids & Identification of Nitrogen & Sulfur Compounds in Coal-Derived Liquids
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 natur...
