Any characterization of coal, physical or chemical, is likely to be influenced by the petrographic heterogeneity of the particular sample. The ultimate objective of this program is the establishment of interrelationships between coal properties and industrial behavior. These include maceral and reflectance analysis, density, various tests of the plastic behavior of coals, Vickers microhardness, and Hardgrove grindability.
This report reviews some of the physical methods which have been and are being used to characterize coals in the Penn State/DOE program.

References to all of these are contained in this report. As another mechanism of technology transfer, the results have been conveyed via more than 70 papers presented at a variety of scientific meetings. The products of this research can be found in 23 more » DOE Technical Research Reports and 49 published papers. Combustion of chars, low volatile fuels, coal-oil-water-air emulsions and other subjects of research are reported here. Another area research has concerned the catalytic effect of minerals and various cations on the gasification processes.
The reactivity of chars, produced from all ranks of American coals, has been studied with regard to reactivity to air, CO/sub 2/, H/sub 2/ and steam. A theoretical and experimental study of the pyrolysis of coal has been completed. During the contract period more than 5000 samples were prepared and distributed. These data include: proximate analysis, ultimate analysis, sulfur forms analysis, calorific value, maceral analysis, vitrinite reflectance analysis, ash fusion analysis, free-swelling index determination, Gray-King coke type determination, Hardgrove grindability determination, Vicker's microhardness determination, major and minor element analysis, trace element analysis, and mineral species analysis. To the extent feasible and appropriate basic compositional data were generated for each sample and validated and computerized. The Sample Bank includes full-seam channel samples as well as samples of lithotypes, seam benches, and sub-seam sections. To further characterize the Nation's coals, the Penn State Coal Sample Bank and Data Base were expanded to include a total of 1150 coal samples.
