    Recently air pollution has been taken up as a puplic nuisance.The source of air pollution arises, chiefly from smokes and gases emitted from chimneys, which are so great in quantity and influence.On the other band, in keeping with a remarkable increase of vehicles in large cities, in Tokyo for instance, exhaust gas has produced injurous effects to such an exteut as not to be ignored any lorger.
    Last year the author made a trip to the United States of America, to inspect the general state of affairs on air pollution.In this paper he describes in details the present phase, mainly in those cities as Los Angeles, New york and Richmond, of air pollution causedby motorcar exhaust gas, the problem of normalization and the cleaning apparatus.

    Recentlyproblems on air pollution have become much discussed among various types of societies. The author described the effect of air pollution on the public health: kinds of air pollution, its relation with meteorological conditions, mechanism of the occurrence of bodily injury, trends in the medical study of the effect of air pollution, and one example method for surveying air pollution in towns which he had learned in the United States.

  • Utilization of Acid Sludge

    We have investigated carbonization of the acid sludge on the utilization of carbonization products and detergency of sulfonate separated from the acid, sludge.When the acid sludge is heated slowly, SO2 evolves at about 90°C, almost terminates up to about 350°C, and the lower saturated hydrocarbon evolves extremely above 500°C.The higher the carboni-zation temperature is, the more the sulfur content of carbonaceous material decreases.
    The activities of carbon prepared from the acid sludge are satisfactory, when it is activated with steam for an hour, after heating at 850°C in the presence of sulfur.
    From the comparison between surface tention, interfacial tention, penetrating, and foaming of Na-acid sludge sulfonate isolated from the acid sluuge and those of the commercial deter-gent, it will be considered the sulfonate is applicable as detergent, though its surface activities is lower than that of the commercial detergent.

    The volatile matter content shows very characteristic change during the carbonization process, that is to say, it decreases suddenly in the temperature range of 300-450°C. From the various experimental facts the authors assume this decrease to be the distillation of the primary tar and, employing the extrapolating curve of the variation line of volatile matter in the range of above 400-450°C to the low carbon percent (ideal carbonization line;V.M.=-0.0192 (C%) 2+1.54 (C%) +29.2), the volatile matter content and the C% of coals, the primary tar content can be calculated.It exists the good accordance between this calculated values and the experimental ones.

  • Studies on Properties and Combustibility of Locomotive Briquette.

    For the purpose of decreasing the burning loss largely due to high burning rate in locomotive boilers, burning collapsibility of pitch briquette was investigated.Colla-psing phenomena, which change in general with coal grades, or under various manufacturing and burning conditions, were indicated to be classified into four types;that is, coagulation, flower-leaf, granule, and swelling.The collapsing phenomena of these types are coused by different combinations of several factors, that is, crack due to rapid heating, action of swelling control, melting due to caking property and separating due to shrinking property at the adhe-sive surface between coal and pitch, and other factors.Further, field tests were carried out to find the relation between these types and burning loss, and the results are: larger ash loss with the coagulation type, larger cinder loass with the granule type, firing difficulty with the swelling type;but these kinds of loss are proved smaller with the flower-leaf type which is considered the most suitable locomotive briquettes.The conclusions are as follows;1) The collapsibility of flower-leaf type, as well as calorific value and tambler test value, is regarded as necessary for locomotiue briquette.2) Even if the material itself belong to the granule type or the coagulation type, the flower-leaf type briguette will be possibly prepared by-proper combination according to the formation theory of flower-leaf type.

  • Briquetting of Non-caking Coal
    Yuzo Sanada, Hidemasa Honda

    It is well known that the briquettability of coal is closely connected with the mechanical behaviours of coal such as hardness and plasticity.We have found that the coal containing absorbed solvent increases the plasticity and leads to increase the briquettability.
    Binderless briquettes of non-caking coals absorbed various solvents have been made under the pressure of 1000-2000kg/cm2 at room temperature.The briquettes made of coals containing absorbed pyridine increase their hardness.The hardness values of briquettes made of coals containing absorbed benzene are almost the same as those made of air-dried alone.The apparent density and the hardness value of briquettes increase with the increase of absorbate content and reach a maximum at an optimum content.
    The higher the apparent density and the hardness valne of raw briquettes are, the higher those of briquettes carbonized at 1000°C become.
    From these results, it is shown that the plasticity of coals plays an important role in the briquetting.
