Coal liquefaction short residence time process research. Second quarterly report, January 1-March 31, 1979
Technical Report
·
OSTI ID:5934640
Process research on short residence time studies includes kinetic studies on a bench scale reactor, residence time studies in the three phase liquefaction systems, and characterization of the initial chemical processes. Failures of electrical heaters and a new compressor prevented operation of the reactor in the last quarter. A detector system for measuring the residence time of solids has been built. Chemical studies show the solvent and coal react to form a preasphaltene adduct resulting in a solvent imbalance. The reaction occurs in the 200 to 300/sup 0/C range where neither the coal nor the solvent by themselves undergo reaction. The extent of adduction depends on the nature of the coal and of the solvent.
