    To meet the postwar increase if town gas consumption, new coke-ovens and producer gas ovens have been installed.However, meanwhile, the remarkable seasonal variations of the consumption made those installations uneconomical.The Tokyo Gas Co.has solved the situaton by the oil-gas process which produces gases with much higher calorific value frdm simpler installation.The new devices in the Senjyu Fact ry were described with a satisfactory result.

    Four coals were separated into portions of different density by the float-and-sink method.The magnetic susceptibility, density, ultimate analysis, proximate analysis and calorific value of each portion were determined and compared.For each coal sample the susceptibility showed approximately the linear relationship with the ash content.Therefore, the ash content may be estimated from the susceptibility measurements without direct determination.The Wiedemann's law on magnetic susceptibility appeared to be valid for coal and further the conditions of ash and molecules in coal were discussed.

    Driving pressure during carbonization of single coal and blended coal were measured by means of oven with movable walls, and relations between driving pressure and properties of coal or coke were studied.
    Maximum driving pressure of Japanese coal is lower than that of American coal imported, 0.19kg/cm2 of Shikamachi coal is highest in Japanese coal and generally below 0.13kg/cm2.Relation between driving pressure, coke button number, fuel ratio and shutter index of coke respectively were studied.When non-caking substance and coking coal is blended, maximum driving pressure decreases along straight line with in-crease of non-caking substance.When two kinds of coking coals are blended, relation between maximum driying pressure and blending proportion shows concave curve and there exist minimum point.

    For the rapid determination of ash in coal and coke, we designed an electric furnace of hot plate type and an oxygen gas feeder.The surface of the plate is heated above 650deg;C.within 10 minutes, and porcelein trays in which 0.5 to 1 gram of fuel is weighed are placed on it.After 2 to 3 minutes, two trays of same sample are covered with one feeder and the samples are burnt to ash feeding oxygen within 3 to 4 minutes.Successive procedure enables to reduce the mean time of finishing of one sample to about 3½minutes.Twenty six fuels were tested.In each test, diff-erence of result results between this rapid method and standard muffle method in ash determinatron did not exceed 0.5 per cent.

    The low-temp.tar-naphtha was fractionated into 30 fractions of 5°C inter-vals each.Some physical properties, of the each fraction, i.e, refractive index, specific gravity, Molecular weight, etc., were determined and the distribution of aromatic, olefinic and paraffinic hydrocarbons was measured.
    Detection of some aromatic constituents was performed and as the results of it, benzene and m-xylene were found.
    Some n-paraffines, whose carbon numbers are 7-11, were isolated by means of extractive crystallization method using urea adduct.

    The constituents of low temperature tar fraction (200-300deg;C) being obtained from so called middle oil from Lurgi oven in Wakamatsu, were studied.Contents of acid, base, and olefin were estimated by acid and alkali treatments.Constituents of neutral oil which were not absorbed by above treatment, the ring analysis (Waterman method) was applied.From these experiments, the distribution of each components at 200deg;C and 300deg;C, respectively, were shown as follows;Acid (43-38%), Base (12-4%), Olefin (19-9%), Aromatic ring (10-13%), Naphthen ring (7-3%), Paraffin chain (18-13%).

    Analysis of a neutral fr.ction (208-216.5eg;C) from middle oil was carried out by the chromatographic adsorption method.Silica gel was used as an adsorbent, and displacement development procedure w., s applied., It was experienced that the separation of constituents of middle oil fraction was not so easily as of light fraction.As a result, the constituents of this fractioni were considered to be aromatic and naphthenic hydrocarbons mainly and a small quantity of crystalline of naphthalene was isolated.
