ABSTRACT:

Progress reports are presented for: task 1 - thermal behavior of slurry reactors used for indirect coal liquefaction; and task 2 - coal liquefaction under supercritical conditions. For task 1, the investigators are experimentally investigating the kinetics of the two step methanol synthesis process in which the reactions are carried out simultaneously in one reactor. Some experimental measurements made during the last quarter are described. For task 2, the revised experimental apparatus for supercritical fluid extraction was built and tested. The objective of this study is to measure mass transfer rates for naphthalene extraction by carbon dioxide to enable the investigators to determine how mass transfer coefficients vary with pressure, flow rate, and bed height. Mass transfer coefficients were obtained at 100 atm and 35 C by the cell model. 14 refs., 5 figs., 1 tab.
