    author delivered a memorial speech on“Studies and surveys onutilization of coal resources in Hokkaido”for a 1961 Prize for the coal section, awardedby the Fuel Society of Japan.
    Of the four main islands of Japan, Hokkaido is rich in natural resources, especiallyin coal deposits ranging up to 10, 000 million tons, which amounts to half of Japan'stotal coal resources.
    However, Hokkaido is still sparsely populated;industrially speaking it is one of theleast advanced areas in Japan today.
    In post-war Japan, re-evaluation of Hokkaido resulted in the enactment of“TheHokkaido Development Law”in 1950, and succeeding to the First 5 Year Plan startedin 1952, the Second 5 Year Plan was brought underway in 1958 which willbe foll -owed up with another new long-term plan storting 1963 .Promotion of industries and utilization of the abundant natural resources are expected to be the center point ofthe new Hokkaido Project.Since 1948 several surveys were made under the abovecircumstances with reference to the Hokkaido development plans, and also studies onutilization of coal, by the author, Mr.W.Hirota and their co-workers during thepast 12 years.
    In this paper the author emphasized the utilization not only of organic substances incoal but also of ash of low grade coal resources as raw material as well as of coalmine gas by draining abundant Ishikari coal field firedamp, and that those materialscan be best utilized in large quantities at coal field sites.
    The content of said paper:
    1) Objectives of the surveys and their relation to the research on coal utilization.
    2) Survey on the fuel consumption per family per year in Hokkaido.
    3) Survey on the quality of coal covering all workable coal fields in Hokkaido.
    4) Studies on utilization of coal ash-manufacturing of gypsum slag cement using slag-tapping boiler slag as raw material.
    5) Studies on the caking pniperty of Hokkaido coals and their characteristics at theplastic stage in carbonization.
    6) Studies on the high pressure coal hydrogenation process with special emphasis onproducing aromatic chemical compounds.
    Lastly the author has expressed his view on future industrial development in Hokkaido.

    Toko Gas Co., with the co-opevation of Tokyo University and Kyushu Refractory, Brich Co., has completed the installation of TG type catalytic crackingoil-gas generator of superior capaity, spending about eight years, At present 8, setsof oil catalytic cracking plants of 1110 kl/day are in operation which are producing2x106m3/day of gas.
    This plant is characterized by gasifying a wide range of oils as raw materials usinga small amount of catalyst. Moreover. the cost of its installaton is very cheap, thegas composition and gasification efficiency are excellent.and the steady operation canbe maintained.
    In the course of developing this plant.efforts and devices were concentrated on thedevelopment of catalyst as well as the generator itself, the details of which are describedin this paper.

    is a summarized report on study aimed at the manufacture ofmetallurgical coke for blast furnace from Japanese coal. Inducing authors'results ofmany researches, a fundamental idea on theory of coal blend for making metallurgicalcoke is at first described. A few methods that are able to produce metallurgical cokehave been found by developing the above mentioned theory and in this paper the outlinesof these methods are stated. That is, the contents of fundamental study and experimentsin pilot plant on briquettecoke method which uses lowcaking and noncaking coals asmain raw materials are described and the raw briraette blending coke.method which isthe application of briquette coke method and possible to save highcaking coal is alsointroduced.

    Coal Hydrogenation under high pressure has been studied for the purpose of producing aromatic chemicals from coal, by using autoclaves of batch-type and a small-scale continuous apparatus in the, Fuel Research Laboratory, Engineering Faculty of Hokkaido University since 1956.
    In this paper, essentials of the experimental results have been reported according to the following research items,
    1) Studies on the relation between hydrogenated oils from various kinds of Japanese coal, such as brown coal, non-caking sub-bituminous coal and caking bituminous coal, aud structural characteristics of sample coals as revealed by Krevelen's structural analysis, , together with chemical and infra-red spectral analyses of oxygencontaining groups of sample coals.
    2) Studies on the applied reaction kinetics of liquid phase coal hydrogenation.This item includes (a) the measurement of numerical values of the reaction rate in coal hydrogenation, expressed as the rate of decrease of benzene-insoluble unreacted coal, covering a wide range of the reachion conditions, (b) analysis of the feature of “mixing” which could occur in a model reactor of liquid-column type, agitated by gas bubbles, and (c) the heat of reaction in coal hydrogenation, by using an apparatus designed for a differential thermal analysis of coal hydrogenation under pressure.
    An example of analysis of the reactor of coal hydrogenation is shown for a rational decision of reaction time and reaction volume.
    3) Studies on continuous liquid phase coal hydrogenation by using an apparatus, capableof treating 8l of coal paste per hour.An example of analyses of hydrogenated oils (acidic, basic and hydrocarbon oils) is shown.Preparation of coal paste and stable operation of the continuous reactor have been also studied.
    4) Analysis of composition of hydrogenated oils boiling above 300°C, produced by a batch-type autoclave.
