    The internal heating fluidized carbonization process of fine coal, using air as fluidizing gas, has been described.The feature of this process is in obtaining semicoke not influenced by oxygen in spite of using air and in that the apparatus and its operation are very simple.Gas and tar have beer considered simply as fuel.The results of laboratory studies and of the operation of the fluidized carbonization furnace, the internal diameter of which is 200mm, have been explained.The uses of the semi-coke have also been discussed.As future development, it has heen stated that the production of town gas from fine coal by fluidized carbonization with the furnace both internally and externally heated is highly promising.

    Japan imports annually about 4 million tons of strong-caking coal for the purpose of manufacturing cokes for metallurgical use.To make cokes by the usual coke oven caking coal is naturally indispensable as its material, however, whether it is impossible to make cokes using non-caking coal as raw material, if any process other than that of coke oven were adopted, was the subject of our study since 1950.
    The Coal Research Institute did finally invent a new coke making process from noncaking coal, which is called “Two-stages carbonization”, after years of close application to solve this problem.This process is mainly divided in three stages, such as, the devolatilization at the first stage, making of raw briquette from grain of semi-cokes at the second and thirdly coking of the briquette by high temperature carbonization process.90% of non-caking coal in quantity, as 10% of caking coal was mixed at the briquette forming stage as a binder, was used as raw material for coke making and cokes as final product with a hardness of 90% drum index at tumbler test were obtained.In industrializing this process the Institute has adopted the fluidized carbonization oven for devolatilization, briquetting machine with feeding equipment for forming briquette and continuous carbonization oven of vertical type for high temperature carbonization and the process was found as established after the long serial and continuous operation. In this article the detailed description concerning the plan of the pilot plant with semi-industrial scale by which the actual test operation mentioned above was performed, conditions of operation and the results of the quality test of coes have been made.

  • Tar Base Coatings for Iron and Steel

    In order to protect iron and steel from corrosion and erosion in the atmosphere and underground which would be harder than might be imagined, various sorts of paints and coatings have been made and put to practical use. But as they require inorganic pigments as extender, they are very expensive and so not widely utilized in spite of their usefulness.
    Tar base coatings for iron and steel described in this paper being expected to pretreat to some degree before their practical use are very cheap and comparable in their efficiency with those of the past. The authors describe the new coatings made from BOJUNTAN as chief material. They are superior to the coatings of tar base paints and hot applying enamels now being widely used in U. S. A. It might be concluded that our success in making them in our laboratory and on a semi-industrial scale would be extended to a large scale.

    From oxidation and further treatment of lignite, the author obtained products of excellent properties as peptidizing, emulsifying disperser for continuous liquid-solid phase of colloidal solution.They were applied successfully to both circulation mud of oil well drilling and cement slurry.It was found that the products were alsoeffective as retarding agent for dispersion of clay particles for cement manufacturing, operation of cement slurry, potteries manufacturing, agent for lowering viscosity of dense media in the mineral dressing, agent for soil conditioner as fertilizer, and raw material for mixed fertilizer from its organic acid compound.The author succeeded in making this research develop to an industrial production.This research entirely owes to the results obtained in the Technical Research Institute, Teikoku Sekiyu Co. Ltd. and Resources Research Institute.

    JOban coal is non-caking brown coal and therefore suitable for general combustion fuel as heat source.On the other hand, it has industrially used in the briquette manufacture, the high pressure salt manufacture, production of synthetic gas by the Koppers-Totzek fine coal gasification furnace, etc. and a great success has heen obtained.
    The author has explained the details of the abovementioned industries and of the high pressure transportation to a great city, as a future chemical utilization of the Joban coal, of town gas or synthetic gas produced from low grade coals at the Jo an district by the Lurgi high pressure gasification furnace.
    The author has also described the outline of the high pressure gas transportation from Taira to Tokyo planned by thg Joban Low Grade Coal Utilization Committee and discussed the plan economically.
