  • Study on Spontaneous Combustion of Coal Underground

    The spontaneous combustion of coal has been studied from several points of view but especially on the chemical side. There were many important factors which made the origin of spontaneous, combustion so that its causes were scarcely found. Therefore, it is difficult to foresee the spontaneous combustion of coal.
    Up to the present, change of humidity, rise of temperature, and odour of mine air have been considered to be the means of foreseeing thespontaneous combustion of coal with which it was rather unreliable or often too much delayed.
    In this paper, it is reported that it is possible to detect the spontaneous combustion of coal by measuring the temperature of mine air, coal surface and coal seam.
    Also the prevention of spontaneous combustion by using asphalt emulsion is described herewith.

  • Safety Measures Taken at Petroleum Refineries

    Arguments have repeatly made from general point of view by various circles on the subject of how to maintain safety at oil refineries. Therefore, here today I should like to speak about the fire of crude oil, especially.
    Crude oil usually contains water, sometimes, we pour water intentionally into the bo-ttom of crude oil tank. Crude oil is viscous, and has wide boiling point ranges and foam forming powers. It is the mixture of various hydro-carbons.
    Therefore, when it once catches fire, water contained in it inflates and over flows the tank (the phenomenon konwn as slop over), or the water at the bottom of the tank boils up (boil over). The so-called “slop over”, and “boil over” are special features in the burning of oils, which cause “Heat wave front layer” to exist on the surface front in of liquid. It is certainly effective in controlling the fire to study why the heat wave case of crude oil or fuel oil fire, cooling, agitation, drawing off of oil etc. are effective. However, these means are not practicable at the scene of a fire where oil and water are violently boiling up with burning flames.
    We have to resort, to some extent, to the auxiliary means such as fire walls, drainage, etc by which we can prevent the spreading of fire.
    I wish to talk on how to control fire by practicable methods by conducting experime-nts and quoting examples.

    Secondary butanol manufacturing plant in the Shimotsu refinery of Ma-ruzen Oil Co. was recently put in stream as the first petro-chemical plant in Japan. This plant consists of following six sections, absorption, polymerization, hydration, alcohol fractionation, H2SO4 concentration and alcohol dehydrogenation. Secondary buta-nol and butene polymer are manufactured respectively from n-butene and iso-butene by H2SO4 method, and a part of butanol is oxidized to methyl-ethyl-ketone. The author described about the process definitely.

  • Effect of Size on the Regeneracy of Coal
    Tsunetaro Kato, Takahiro Tsutsui

    In some elements which have effect on the oxidizing reaction of coal, temperature and coal size consist of the sample are greater one.
    As coal was pulverized and specific area is increased, regeneracy of oxidizing heat in it is increased as well as absorptive velocity of oxygen.
    Therefore rising grade of temperature in coal is increased, and properties of ignition and combustion of coal become greater.
    We obtained the relationship between size and regeneracy of coal by this study, and described the size of coal which have effect on the properties of ignition and combustion, and the relationship between properties of spontaneons combustion and coal size slightly.

  • Effects of Various Bricks on the Pyrolysis of, Petroleum Oil

    When oil is cracked on the fire brick to produce lower olfins, the com-position of cracked gas varies with the kinds of bricks.
    Cracking stock (paraffinic petroleum heavy hydrocarbons) was pyrolyzed with super-heated steam in stainless steel reactor (50mm∅) packed with brick (4-7mesh, 500cc) and heated externally.
    At 700°C, high ethylene contents were obtained using chamotte brick with Ni, chrorn brick, silica brick and magnesia brick. Yield of ethylene was 27-25% by weight and that of total olefins was 67-62%. These values are higher than the yield obtained by cracking on chamotte brick.
    When Ni-chamotte brick is used, lower reaction temperature can be used than other. bricks are used.
    However, life of this brick and method of addition of Ni on chamotte brick must be-investigated furthermore.
