    (Chiyoda Chemical Engineering & Construction. Co., Ltd.) SYNOPSIS: -In recent years, feed stocks used in synthesis gas production have been gradually turning from coal to petroleum sources. Hence, we may actually consider this period as the turning period for resources of gas production. In view of the development of natural gas resources and expansion trends of refineries in Japan, an abundant supply of petroleum derived feed stocks may be expected. Thereby this will hasten this transition from coal to petroleum resources.
    In synthesis gas production methods, there are (1) the catalytic reforming process, and (2) the non-catalytic partial bombustion process. Although there is another method which may be considered as a combination of the above two processes, actually synthesis gas production may be confined to the above two processes. The advantages of operation under pressure, which is applicable to both processes have gradually become apparent. The Texaco process is one of the typical pressurized gasification process by partial combustion. This report covers the description of the Texaco process with a flow-sheet and operation data and also explains the essential points of the main equipments. Furthermore, a thorough explanation of the reaction mechanism for the partial combustio process, and, as reference, data of the changes in equilibrium composition of the generated gas at various temperatures obtained from equilibrium calculation of reaction are given .Moreover, the advantages of the Texaco process were pointed out with a comparison with those of other gasification processes. Finally, due to lack of space it was not possible to explain the synthesis gas purification process in detail but readers may reer to aprevious report written by the author, for further information on this subject.

    author tried to use the Leitz's heating microscope, designed for determining the melting behaviour of inorganic substances at high temperatures, in order to observe the process of coke formation directly and continuously, and reported the interesting.results onthese matters.
    In this paper, the author has studied the process of softening and melting in Miike coals and its ashes. At the same time, the petrological study has been done, and have compared these phenomena with the former results.
    The results, of experiments were summarized as follows:
    (1) From the experimental studies on the petrological constituents, it was recognized that the accumulation of exinite-Durite, one of the important petrological constituents in Miike coal, was rich in the part of low specific gravities (&1.25) and Vitrite high ones.
    (2) The softening and melting curves of coal ash had showed generally the change points of minimum and maximum, but it has been recognized that these temperatures in Miike coal are particularly low, moreover, the beginning point of softening in the parts of low specific gravities is nearly agreed with the beginning point of melting.
    (3) As the characteristic changes of coal specimens, the small cracks grew up with the increase of temperature, the reflectivity of coal surface increased. Then, the surface changed into dark, soon began to swell.
    Thus, it has been shown that all of the swelling phenomena in Miike coals is always peculiar, besides its temperature is lower than that of the other coals.

    1953, the author has been study ing the palynology on Paleogene coal' field. The samples analysed have been taken from the Ishikari, Rumoi, Kushiro and Kabato coal fields in Hokkaido and Kuzi, Joban, and Ube coal fields in Honshu.
    The sample has been macerated by Schultze's solution which is the mixed solution of nitric acid and potassium chlorate.
    Many pollens of the broad-leaf trees are picked up from Paleogene coal of Hokkaido but pollensof conifer trees are few in number.
    In Neogene coal, conifer pollen is abundant.
    By pollen analysis of coal, it is supposed that Paleogene coal seams has deposited warm condition.
