Abstract:
A method of treating fly ash and fly ash treated thereby, the method involving contacting ammonia-laden fly ash with an organic base-containing treatment composition, where the organic base causes the ammonia within the fly ash to evolve from the fly ash. The treatment composition preferably includes an effective amount of one or more amines. The treatment compound may be applied to the fly ash in any manner effective to disperse the treatment compound among the fly ash.
