    Akabira Colliery installed a coal preparation plant in 1941 and started itsoperation in 1943.At the beginning, its capacity was only 210t/h, and after amalgamating withKami-Utashinai Colliery, it was raised up to 280t/h.With the increase of coal output, we studiedan advanced technology on coal preparation, and completed the installment of conspicuous coalpreparation plant.
    At the present intensified rationalization, many parts of the plant have been improved and wellequippedsuch as coal preparation system using Takabu-jig, applications of the automatic refuserejector, the resonance screen for clean coal dewatering, Humboldt-centrifuge and Konturbex.The profit obtained after rationalization is expected to have attained to the sum total of about 600million yen.

    -The production of petroleum aromatics in Japan amounted to 98, 168tons in 1960, corresponding to about 40% of total aromatics including those from coalcarbonization.Benzene fron petroleum occupied about 11% in the total benzene production, toluene about 57% and xylene about 82% respectively.The increasing amounts of petroleumaromatics are being consumed as raw materials for various synthetic high polymers, such assynthetic rubber, fibre and plastics.Studies on utilization of toluene, xylene isomers andhigher alkyl benzenes are necessary for further development of petroleum aromatics.

    It is well known that the burner is characterized by its inspiration ability of primary or secondary air. Experimental studies about air inspirations are reported from A.G.A.etc., but the practical analyses of the data are reserved. The content of this report is that the mechanism of inspiration is macroscopically denoted by the burner equation (t) which makes it possible to establish the theory of interchangeability of fuel gases on domestic bunsen burners.

    Mid-east crude oil generally contains 2-4%sulfur.When this oil is usedfor Texaco gasifier as raw material, and the generated gas is introduced to hot carbonate or MEA CO2 removal unit after CO is converted to H2 and CO2 without foregoing desulfurization, most of the sulfur contained in the charge oil will enter into the regenerated CO2, and H2S content in CO2 will be as much as about 1-2%.
    In order to desulfurize CO2 with absorption method, there would be no other better processthan Alkazid-Dik process and dry box process is expensive in the cost of equipment and operation.To convert H2S to S by Claus process, H2S content is too low.
    Author established a new process for the desulfurization of CO2.In this process, H2S in CO2 is catalytically converted to SO2 adding 02 before converter.Then, after purifyingthe converted gas, SO2 is scrubbed and recovered by NH4HS03-(NH4) 2S03 solution, which is used for (NH4) 2SO4 manufacture after H2SO4 addition and SO2 recovery.
    Author designed and constructed a plant by this process.In this report, the reaction conditions and catalysts for the catalytic oxidation of H2S are investigated.At the temperature lower than 500°C, ZnO catalyst and Fe2O3 catalyst have shown H2S conversion greater than 99.8% at the residual 02 of 0.1-0.2%.Generation of SO3 mist was not observed and increase of organic sulfur was very small.

    The carbonization process of briquets is operated to utilize the vast reservesof non-metallurgical grade coal, and to produce the cokes suitable for blast furnace use andhaving uniform size and quality.
    In this report the heat transfer curve at surface and center of the spherical briquet wasdetermined, and the overall specific heat Op was calculated by using the equaiton of unsteadystateheat-transfer that one of us, S.Sugiyama, derived.The calculated value of Op, 0.33-1.48 [kcal/kg°C] was obtained.
    On the other hand, the reaction rate coefficient h for thermal decomposition of briquet wasdiscussed.

    The calcium phthalate was investigated with calcium naphthenate to solubilizein lubricating oil.The purpose was to make high alkaline lubricating oil additive whichwould prevent cylinder liner corrosion by formation of calcium sulfate and by fixing sulfuricacid produced in a large two-cycle diesel engine as the result of using boiler fuel whichcontains high sulfur.
    1) In the experimental result, both the calcium soaps, which are consisted of ratio in onemole of phthalic anhydride, two mole naphthenic acid and some of emulsion lubricating oilwhich contains colloidal calcium hydroxide, were dissolved quantitatively into the lubricatingoil.The above mixture is dehydrated after completion of the formation of soaps in theemulsion lubricating oil, which is consisted of 22% water and strong base number KOH mg/g66, and then by heating at elevated high temperature around 320°C, and stirring strongly atabout twenty minutes and under every atomospheric or high pressure conditions, thus gotthe above calcium soaps of phthalic acid and naphthenic acid dissolved in the lubricating oil.And the oil-dissolved calcium element was more quantity than calcium equated to the both.acid values of phthalic acid and naphthenic acid.
    2) The mixed soaps of one mole calcium phthalate and one mole calcium naphthenateare added into the lubricating oil, together with more than 1.5% calcium hydroxide and byheating and stirring same as above, we got both calcium soaps dissoved in the lubricatingoil.
    3) The oil-solubilized calcium soaps of both carboxylic acids were considered to form anew compound and to be able to use as high alkaline oil additive.
    4) The oil-insoluble matter issued by over-loaded reactive conditions may be able to useas a grease having high dropping point.
