    After the war, heavy oil has become to put to practical use for coal in the cer-amic industry as regards the points raised in the elevation of quality and the reduction of pro-ductlon cost and our attention has greatly been called to the burner and its aPProDriate use.
    Under the ministry of Education, Research Subsidy-1963, No.103 Committee in Japan Society for the Promotion of the Science investigated the ceramic factories on the items such as burner, furnace, operation, etc. and completed the reports from 80 factories together with the theoretical considerations
    It presents the tables which are made by testing the properties of heave oil, faculty of burner, ceramic furnace and its operation on each of the cement rotary kiln, and furnaces for pottery, refractory materials and glass melting.
    In conclusion, heavy oil combustion in the ceramic industry has greatly cut the fuel cost and saved manpower, moreover, attained the high temperature firing which results the inprovement of quality. On the other hand it has also shortened the life of furnace, and brought about the questions of breakage of brick, super heating in the upper part, etc.
    These should be settled by improving not only the burner but also the structure of furnace and its operation.

    The author investigated the effectiveness of several typical heavy oil additives which have become to our interest in their industrial use on both of the labo-ratory and the practical use in the patrol boats. Especially from the practical viewpoint, he emphasized the additives on some phenomena and combustion in the heavy oil addition and on the effect of the engine rather than he does the additives themselves, i. e., the theoretical consideration. of which he describes in this paper some detailed merits and demerits.

    (I) Synthesis of Hydroquinone from p-Diisopropylbenze by the Liquid phase Oxidation.
    p-Diisopropylbenzene is produced as a by-product in the synthesis of cumene from benzene and propylene. This compouhd was oxidized at 85°C in the presence of sodium carbonate and sodium stearate, the former being used as a pH conrtoller and the latter as an emusifier. As the catalysts, benzoyl peroxide, cobalt naphthenate as well as mono-and di-hydroperoxide of p-diisopropylbenzene were used.
    The-OOH% was largest, reaching up to 57.5%, when the dihydroperoxide was used as an oxidation initiator. The main oxidation products were mono-and di-hydroperoxide and di-compound seems to be unknown, the melting point of which is 142-144°C 42-144°C.
    Mono-hydroperoxide was decomposed with 13% H2SO4 and converted to australol with 54% yield. Di-hydroperoxide was, converted to hydroquinone with 60.5% yield in the decomposition with 20% H2SO4. Na2SO3 reduced di-hydroperoxide to the corresponding dialcohol quantitatively.
    (II) Synthesis of'Hydroperoxide of p-Di-sec-Butylbenzene by the Low Tempoerature Oxidation.
    Mono-and di-hydroperoxide of p-di-sec-butylbenzene were obtained by the atmos-pheric oxidation at 95°C and in the presence of water, sodium carbonate, sodium stearate and catalysts. The catalysts used were benzoylperoxide, mono-and di-hydroperoxides of the said compound. The maximum yield of -OOH was obtained when the di-hydroperoxide was used as an oxidation initiator, reaching up to 39.5%.
    The di-hyroperoxide was plate white crystal, melting at 82-83°C and the structure of which was confirmed by the infrared spectrum and elementary analysis. The mono-hydroperoxide was light yellow color liquid.
    The di-hydroperoxide was reduced quantitatively to the corresponding dialcohol by the use of sodium bisulfite which melted at 79-80°C. The sulfuric acid catalysed decomposition of di-hydroperoxide produced hydroquinone, whereas mono-compound p-sec-butylphenol and methyl-ethyl-ke ton.

  • Studies on Producer Gas Reaction in Fluidized Bed of Coke Particles

    In order to study the effects of fluidizing conditions upon the overall rate coefficient of producer gas reaction in the fluidized bed, coke particles both of uniform size and of wide size distribution are gasified with the air, by which the particles are fluidized, and the overall rate coefficient of reduction are obtained.Inner diameters of reactors used are 5.2cm, 5.5cm, 8cm, 11cm, 15.5cm and 25cm respectively.Comparing the overall rate coefficient of reduction with the rate coefficient of chemical reaction, it becomes apparent that the effects of agglomeration or that of turbulent diffusion in fluidized bed are prominent when small particles are gasified at high temperature.
    When coke particles with wide size distribution are gasified in steady state, small particles are apt to be elutriated from the fluidized bed by the gas produced, becoming the cause of low carbon efficiency, so the theoretical and experimental studies are performed to analyse the above phenomena, grapsing the kinetics of coke particles in steady state gasification of fluidized bed.
