Coal humic substances for the treatment of wastewater from stack gas scrubbers, coal conversion plants, and other coal utilization facilities. Completion report

Technical Report ·
OSTI ID:5821726
Most processes for the conversion of coal to liquid or gaseous fuels, retorting of oil shale, or extraction of oil from tar sands produce relatively large quantities of by-product wastewater. Coal humic substance is a complex organic material prepared by the partial oxidation of coal. This report deals with the uses of coal humic substances for wastewater treatment. The first section is a review of humic substances and their applications to wastewater treatment. The second portion deals with laboratory studies of coal humic substances used for wastewater treatment. The removal of radiolabelled organic compounds from wastewater is described. The interaction of coal humic substances and fly ash is also discussed. Certain types of fly ash are possible sources of base for the preparation of coal humates from coal humic acid. The interaction of coal humic acid with fly ash is compared to that between fly ash and salicylic acid, a low molecular weight analog of one of the major structural entities in coal humic substances.
