    Soil conditioner, if it be understood in a broad sense, is a substance to improve physical and chemical properties of soil, and it has a history of long period.A compost and lime have so far been utilized.In recent years, however, based on the knowledge in modern soil physics and chemistry, the soil conditioners which are getting popular have been yielded by introducing to the agriculture the results obtained in the fields of polymer and coal chemistry.
    These new soil conditioners may be classified into three groups: synthetic polymers, humus substances, and inorganic rock substances.
    This paper describes chiefly the humus substances as to its kind and effect on soil improvements.
    In order to develop the soil conditioners, it is necessary to advance their researches without underestimating their effect.

    This process is a kind of wet oxidation completed by Dr.Gammarco during 1954-1955.Hydrogen sulfide in the raw gas can easily be removed to less than 1ppm by only one stage of absorption under ordinary pressure.This process is applicable under the conditions of temperatures from room to 150-200°C and also of pressures from ordinary to high pressures.Alkaline arsenates and arsenites are used as new absorbents.
    This process is widely applied for the removal of hydrogen sulfide from coke oven gas, natural gas, oil-cracked gas and viscose waste gas, etc.
    This paper describes the principal reactions of absorption and reclamation, flow diagram of the actual industrial apparatus, and its application limit.
    It may well be applicable for the H2S removal from gases containing a large amount of CO2 or for the desulfurization at comparatively high temperatures (60-150°C) to Lower H2S content down to ppm.

  • Studies on Purification of Acetylene from the Burner Gas Formed by Partial Oxidation of Methane(II)
    Studies on the Solubility of Diacetylene into Methanol and Methanol-Water Solvent and the Separation of Acetylene from Diacetylene in the Methanol Solvent.

    In order to obtain acetylene of high purity from the burner gas formed by partial oxidation of methane there may be encountered such a practical problem as the removal of various higher derivatives of acetylene containing in small amounts.Our determinations of the solubilities of diacetylene, its representative, in methanol and methanol-water solvents indicated that acetylene could be separated from diacetylene in such a simple manner as an addition of water to methanol.

  • Burning Velocities of Preheated Town Gas(II)
    Methane, Propane and Butane-Air Mixtures

    The auther have investigated the influence of the initial mixture tempe-rature on the burning velocities of Town Gas, Methane, Propane and Butane-Air Mixtures.The result showed that the maximum burning velocities of these fuel gas, (Sb) max.(cm./sec.) are proportional to the 1.5-1.7 th power of the absolute initial mixture tempearture Ti°K.i.e.(Sb) max=aTi1.5-1.5.
    Therfore, where high-speed combustion is requrired, an apreciable gain in rate of heat production J (kcal/mm2.sec.) can be had by increasing the initial mixture temper-ature.For instance, In the case of Town Gas, if the lenght of the inner cone of the flame are constant, Jmax for the initial mixture temperature of 373°K, 473°K and 573°K are respectively 1.4, 2.1 and 3.1 times larger than that for the room temperature.
