Under Facet I, 49 coal samples have been added to the Penn State/ERDA Sample Bank. Sixty-six characterized coal samples and 734 sets of analytical data were provided upon request to other agencies. Facet IV-A research on reactor development and operation has led to the construction of a cold model for the flow of gases through the combustion pot. Flow analyses indicate that even with relatively slow flows the mainstream flow is turbulent. Methanol and water densities of a series of char samples, studied under Facet IV-B, were found to be quite similar. Deposition of carbon on chars from the cracking of methane results in a reduction of char surface area and open pore volume. Siderite and calcite catalyze the cracking of methane at 900/sup 0/C. No catalytic activity is evidenced for dolomite, pyrite, illite, quartz, rutile, or kaolinite in this reaction. From a comparison of refractory and water-cooled bottom blocks, under Facet V-A, it was found that even significant changes in the furnace bottom temperature can only cause moderate changes in plane-flame furnace combustion performance.
