| Research Abstract |
This project, entitled as "Japan-USA Joint Research Program - Studies of Coal Macrostructure and Surface Characteristics, was started in April 1989 in an extension of research collaboration between laboratories of Prof. J. W. Larsen, Lehigh University, and of Prof. Y. Sanada, Hokkaido University, since the latter gave an invited lecture on current activities of coal science in Hokkaido University at 1988 Gordon Research Conference on Fuels Science.
The purposes of the project were i) to perform fundamental researches on macrostructure of coal, on interaction between the macromolecule and solvent, and on chemical reaction characteristics of these molecules, ii) to exchange the latest progress in the research and its relating fields obtained in both countries, and iii) to expand the collaboration to have further progress in this particular research fields which is expected to meet a growing need for future coal utilization. During the past two years of the project from April 1989 to March 1991, static and dynamic swelling measurements together with NMR and ESR measurements were carried out using different dilatometers for the same coal samples and solvent at both sides. On the basis of these measurements the coal macrostructures were estimated and determined and contributions of intermolecular forces were evaluated for hydrogen, - a nd ionic bonds. In addition, a simulation model for swelling of coal particles were developed to explain unusual change of the coal slurry viscosity with increasing temperatures.
These results were presented at international conferences such as 1990 Gordon Conference on Fuels Science and published in current research journals such as "Energy and Fuels" and "Fuel".
