(Basic properties of coals and other solids)
Research on coal properties continued. During the past quarter we have studies another Argonne premium coal, Wyodak Subbituminous, through its heats of immersion measurements in the same series of acids as that reported previously. The experimental conditions and coal pretreatment temperature (110{degrees}C for 14 hours under vacuum) were exactly the same as described in our previous report (QR {number sign}5). The second part of this report describes our attempt to compare the basic properties of coals and coal-liquids through their heats of interaction with a variety of Broensted acids of varied strengths. We have compared a coal-liquid (YP35) with Exxon Rawhide coal (both obtained from Exxon) and a Wilsonville coal-liquid (V182) with IL{number sign}6, obtained from Southern Clean Fuels, Wilsonville, Alabama. The excess coal-liquids (5 ml in 25 ml acetonitrile) and coals, as slurries, (5 g in 25 ml acetonitrile) were titrated against strong acid solutions in acetonitrile, using the Tronac 450 titration calorimeter. 9 figs., 1 tab.
