Research during the past quarter centered on three studies related to liquefaction reactivity measurement procedures, and on continuation of reactivity screening runs for the Penn State Premium sample suite. The reactivity measurements on 4 Argonne Premium coal samples in four solvents were completed. The data from this study verified our previous conclusions concerning the impendence of relative reactivity ranking to liquefaction vehicle (solvent). While the absolute liquefaction conversion is a strong function of solvent type, the relative reactivity rankings in terms of toluene-solubles is identical regardless of the vehicle employed in the microautoclave reactor. A second study on the catalytic effect of the reactor wall proved that no such effect was present. A final study on the effect of mixed solvent systems containing 1-methylnaphthalene and anthracene or phenanthrene failed to indicate any enhancement of the liquefaction reaction by 1-MN as has been recently reported by Kwon and McMillen et al. 2 refs., 9 figs.
