    In order to cut down the transportation cost which had taken a great rate of coal price, a long distance pipeline transportation of coal slurry was accomplished in U.S.A.
    The coal slurry consists of ?8mesh fine coal and its density is Coal: Water=60: 40 by weight.This slurry is prepared at mine and pumped a distance of 174km by three pump stations through 10 inehes O.D.steel pipeline. Aunnal capacity of the pipeline is about 1, 500, 000 tons and the cost of the transportation reduced about 2/3 of freight charge.
    The slurry also proved to be pumped into barges, shipped about 1, 000 km and stored in the oil tanks.
    Slurry reached at power station is dewatered, dried and burned in the usual boiler.More effective methods of slurry utilization have been developped in U.S.A., for example, direct firing of slurry at cyclon furnace was experienced.
    The success of the coal pipelining has been attracted world attention, and some countries, including Japan, set forth long pipeline projects.

    Systematically blown asphalts were prepared, and their dielectric properties were measured at the frequency of 30c/sec-1Mc/sec.Difference of the properties due to the raw stock and degree of blowing, and relationship between the properties and other ones were studied.
    Moreover, a few informations were obtained from the measurement of the properties by dissolving the asphalts in carbon tetrachloride.

  • Studies on Formaldehyde Formation by the Catalytic Oxidation of Methane (V)
    The Formation of Formaldehyde by the Nitric Oxide Catalyst

    The experiments were carried on the homogeneous gas phase catalytic oxidation of methane by oxygen in the presence of nitric oxide and we aimed to make clear the effect of some dominant conditions on the reaction in which are there involved the concentration of catalyst and oxygen, contact time, the preheating temperature of feed gas and the kind of solid catalyst.As the optimum condition, a feed gas composition of 1-3% nitric oxide, 10% oxygen and 80-90% methane, a reaction temperature of 600-700°C, and a contact time of 0.2-0.6 sec.are shown to be preferable and under these conditions we obtained the following good result that the formaldehyde concentration in the reacted gas mixture reaches to 2.0%, the formaldehyde yield is as high as 30% refered to reacted methane and 50% of oxygen is consumed in the reaction. This reaction is consecutive reaction which consist of two steps, the former step forms formaldehyde and water from methane and oxygen and is the first-order reaction on the second-order concentration of oxygen, and the latter step forms carbon-monoxide and water and is the reaction which comprises the product of the first-order term of the formaldehyde concentration and the that of oxygen respectively.The active form of nitric oxide catalyst is nitric dioxide which is formed by the oxidation of nitric oxide and presumed to exist as an unstable intermediate during the reaction.

  • Recording Differential Thermobalance
    Yoshio Kawana, Ritsuo Takeuchi
    1964 Volume 43 Issue 2 Pages 125-133

    A recording differential thermobalance has been devised by the authors, which can readily follow the course of pyrolysis of various samples under vacuum or under the flow of gases up to about 1, 000°C by automatically recording both the differential and cumulative weight loss.In this report, the structure and Mechanism of this thermobalance have been mainly clarified.
    This balance takes samples of 0-1g and can record total weight changes up to 0.8g in the four weight loss ranges of 0-100mg, 0-200mg, 0-, 400mg and 0, 800mg The sensitivity of the differential weight loss can also be changed in the four steps. Constant heating rates of samples can be controlled in the range of 0-20°Cmin.
