Abstract
The coal has been picked up as a pinch hitter on a energy policy at present and future. Generally, the coal inustry must be erected at a big coal field by means of the cheep cost. Accordingly, it seems very difficult in Japan, but very easy in a foreign country.
In future, the coal industry will take three common ways. Those are the Car-bonization, the Gasification and the Liquefaction. The carbonization will be trend to a formed coke process. And it is supposed that a generation of the electric power is the best utiization of the C. O. G. The gas by a coal gasification will be used to the synthesis of Methanol, Synthol, NH3 or S. N. G. But the methanol synthesis will be the most hopeful at a oversea coal field. The liquefaction will be affected by costs of petroleum, but in the 1980's it will be success including of the technical security.
Using coal prices by a foreign country base, trial calculations of these manufacturing costs were done comparing with costs of products from a natulal gas and a petroleum.
As a consequence, there will be some effects of the coal price, but coal industries will have a bright future.
