    The coal industry in Japan will yield to the petroleum industry as energy sources in a few years. This is chiefly because of the high cost of coal, and from the viewpoint of merit, unless coal is supplied with at lower prices than 80% of petroleum price per kcal, it will lose the future market.Therefore, we are devoting ourselves to make progress in the technique of hydraulic mining, aud in addition to this it is necessary to make advance in the underground gasification of coal.
    Coal for gas use is placed upon the same post as that for energy sources, and thus the coal chemical industry must start from the new standpoint.
    Imported fuels, mainly petroleum, will bring a great liability upon the trade balance of Japan, and so in order to solve the economical problems, it should be necessary to make efforts for the development of the coal science and technology.

    Iron manufacturing industry is a matter of the combined chemistry and physics at high temperatures, and it cannot be considered without heat and temperature.
    After many changes of the iron industry, fuels to be used have gradually been changed, however, in general there was no liberty to select fuels for the iron industry in Japan. And conse quently, ittook a comparatively minor stride.
    After the war, various restraints being put upon the iron industry was canceled and the following epochal work system has been adopted, i. e., (1) quality control, (2) heat control, and (3) instruments control.
    Especially a wide-scope of freedom of liquid fuels selection has greatly changed the former heat control system, which has led up to the technical revolution.
    Finally various fuel problems were outlined facing at the individual divisions of the iron industry.

    Methods most widely used in determining the hardness of materials are static indentation methods.These involve the formation of a permanent indentation in the surface of the material to be examined, the hardness being determined by the load and the size of indentatation formed.
    Experiments have been made to find the conditions of these testing methods for coals .In testing for coals with diamond pyramid method, using either the ordinary Vickers or microhardness tester, the load used is generally above 2kg and above 200gr, respectively .In these tests, the duration of the load is an important factor.With the Vickers tester, the full load is usually applied for 1.4 seconds.With the microhardness tester, the time of application is 30 seconds.
    The micro-Vickers and Knoop hardness values are almost identical with the ordinary Vickers hardness numbers.In addition, the Knoop indenter often produces satisfactory indentations in the materials such as anthracite, semi coke and coke which are hardly indentable by the Vickers pyramid indenter or dy spherical indenter.

    Balance in the second and third reports, me understood that Zfi-Cr-Mo-K2CO3 Catalysre was most suitable, me investigated in this report the effects of reaction temperature, pressure, space velocity and composition of raw gas.
    As the results, we found the facts as follows's,
    1) Asuitable range of reaction temperature is 400-450°C and, with rise of reaction temperature, gas Consumption ratio (CO/H2) and formation CO2/CH4 and CnHm increase gradually.
    2) Reaction pressure don't give notable effects on contained balance of isobutanol in liquid of formation but latter increase with pressure.
    Under 200kg/cm2, a increasing tendency of formation of water is observed.
    3) Only for contained volume of isobutanol in liquie of formation, a suitable space velocity is 6, 000.But, from a point of view of formed isobutanol quantity (Space Time Yield), a sutable reaction temperature and space velocity are respectively 450°C and 15, 000.
    4) Contained volume of isobutanol in liquid of formation (A) is good at about CO/H2=1/1 in gas consumption ratio and in experiments of use of raw gas of various ratio (CO/H2), when composition of raw gas is about CO/H2=1/1, A is much but methanol and water are formed very little.Little water formation enlarge activities of this catalyser.But the richer CO Content in raw gas is, the more formation of CH4, CO2, and CnHm is.
