Trend of Research on Coal Science

Abstract

The petrographical constituents, the physical and the chemical properties of Japanese coal are different from those of foreign coals. Therefore, it is necessary to establish the all round knowledge as to the characteristics of Japanese coal.At present, the research on coal science in this country tends toward the fundamental research by using the all kinds of analytical method, such as N. M. R.-, E. S. R.-, Infrared- and Mass-spectrometer etc., and the applied fundamental research manufacturing the humic acids, tar enamels, briquette coke for blast furnace use, smokeless fuel, activated carbon and artificial graphite etc. from Japanese coal only.Particularly, it is expected to clarify the characteristics of Japanese coal as follows:1) physical and chemical structures of coal2) construction of critical points recognized at carbon content 85-90% (d . a. f.)3) properties of heat treated coal in the early stage of carbonization4) relation between aromatic H content and aliphatic H content in connection with coal rank5) difference between Japanese coal and foreign coal5) difference between Japanese coal and foreign coalIt is moreover requested to cultivate the new utilization technique fitted in the Japanese coal.For instance, the research on physical and chemical properties of heat treated coal in the early stage of carbonization is now progressing in the cooperation of Resources Research Institute, Waseda University and Coal Mining Research Centre by using the same sample prepared carefully for this object.On the other hand, the Division of Coal Scieace installed in the Fuel Society of Japan is now promoting the development of research on coal science, and held the 3rd conference of coal science for one of this purpose in Tokyo on Nov . 11-12, 1966.The 4th conference of coal science will be held at Fukuoka and Kita-Kyushu city in this year.
