    In this paper, elucidation is given on the applications of radioisotopes to the petroleum industry, citing some applications chiefly in the United States.They are divided into two groups, applications as tracers and radiation sources.As the former, the author explains the application to the chemical analysis, researches on the reaction mechanisms and transmission of materials (distillation, mixing, stirring, wear, etc.) And the latter is the fixed radiation sources (radiograph, thickness gauge, level gauge, hydrometer), movable radiation sources (flow of fluid in pipe, leak test of pipe, etc.) and radiation energy sources.

  • Separation of Aromatics with Silica Gel
    Tozo Amemiya, Kozo Kurokawa

    Silica gel having good selective adsorptive power to aromatic hydrocarbons was prepared from sodium silicate and hydrochloric acid.Its selective adsorptive capacity to toluol was larger than those of the ever-known silica gels.Separation of aromatics from platformate and other petroleum fractions was successfully carried out with the gel according to the procedures used in the Arosorb Process and desulfurization of petroleum fraction was also possible with the gel.

  • Mixed Stability of Diesel Fuel Oil

    It is heard that in every case that good quality fuel oils are mixed as diesel fuel, the amount of sludge becomes enormously abundant, which'causes many unexpected troubles in engine use.This is entirely due to the lowering of mixing stability of diesel fuel oil and still more to the influence of components and properties of mixed oil, moisture content and temperature of oil, oxygen and humidity of the air, and other impurities.It should not be too great a consideration to pay in such a recent tendency that the quality of fuel oil is deteriorating.
    The auther mixed a few general light oil and straight run or catalytic cracked fuel oil at various proportions, the results of which have been reported especially on the stability of mixed oils and the simultaneous phenomena.

  • Moisture Determination of Fine Coal by Dielectric Method
    Wataru Funasaka, Teiichi Ando, Yasumi Kamino

    The standard method for determining the moisture content in fine coat is the drying one, which, however, takes us more than one hour, and thus it is inadequate to control the moisture content in the repeated or continuous determination.For satisfying the difficulty, it is of conveniece to use the dielectric method. The dielectric constant of water is remarkably different from that of coal, and so in accordance with change of moisture in fine coal, its impedance is also changed.This method is applicable as being able to indicate electrically that change.
    Rapid determination is made within the narrow error of 0.2% moisure in fine coal and more over the short required time of two minutes, if only the relation between the.moisture content of each coal and its impedance is previously prepared.It might be concluded that the dielectric method is proper for the repeated or continuous determi nation of moisture in fine coal.

  • Considerations on the Softening and Melting Bellaviour of Coal Ash

    By the Leitz's heating microscope, the author examined the softening and melting behaviours of coal ash (size of sample is 27mm3).The characteristic melting curves of coal ash were obtained from the results of these researches.
    These curves had showed the change points of minimum and maximum, so severally named it the beginning point of softening and melting, moreover suggested the one way to express the melting behavoir of coal ash by means of this characteristic points.
    According to the comparison between this way and JIS, method also recognized that the former was better than the latter in the measurement of melting point.
