Use of basic nitrogen to chemically clean coal: Quarterly report No. 6 for the period March 15, 1988-June 15, 1988
Studies of the effect of the concentration of basic nitrogen compounds in coal derived distillates as solvents on coal desulfurization were continued. Mild coal liquefaction runs were made using a solvent consisting of 25 wt % tetramethylammonium hydroxide pentahydrate (TMAP) in a coal derived distillate. A comparison has been made of the results obtained from these runs and from earlier runs in which coal derived distillate or 5 wt % TMAP in distillate was used as the solvent. Under comparable reaction conditions, TMAP showed little if any positive effect on the desulfurization of the coal studies. However TMAP appears to have a small but positive effect on the conversion of lignite and subbituminous coal to pyridine soluble product. 2 tabs.
