    Fuel cells have recently attracted much attention.The present authors have discussed on the economical and practical prospects of fuel cells as well as their structures, electrode reactions and features and obtained following conclusions.
    Fuel cells are very promising not only as mobile or independent power sources, but also as large power stations if cheaper fuels will be utilized in future by the development of petrochemical and natural gas industries.It will be also possible that fuel cells will be used as substitutions for electric power generators, various electric cells and gasoline engines.

  • Studies on the Oxidative Degradation of Coal.(V)
    Oxidative Degradation of Artificial Coal

    Artificial coals prepared from cellulose, lignin, their mixture, lignite humic acid and brown coal were compared with natural coals by their behaviours against IN HNO3 oxidation.
    The results of oxidation of artificial coals are comparable to these of natural coals, which were reported previously, and it seems likely that the chemical constitution of the formers is similar to that of the latters, i.e., both of them consist of two distinctivestructural parts.The effects of progress of artificial coalification on the nature of artificial coals are similar to that of increasing in rank on the nature of natural coals.According to these evidences it seems favourable that artificial coals are suitable model of natural coal, but, there are some distinctive characteristics between cellulose coal and lignin coal.It seems difficult for lignin to be coalified upto higher rank coal.
    The process of artificial coalification was discussed by the above-mentioned evidences.and it was concluded that artificial coals are formed as the result of repeat of condensation and destruction reactions of the intermediates, which are formed from, original materials by the various decomposition processes.

  • Hardness of Macerals in Kayanuma Coal

    The Knoop hardness of vitrite, exinite-durite, mineral-durite and coaly shale of various coal seams in Kayanuma coal field (Hokkaido, Japan) has been measured.The hardness of macerals decreases in the following order: coaly shale, mineral-durite, exinite-durite and vitrite.The hardness of coaly shale and mineral-durite depends on their mineral contents.The relation between hardness and carbon content of various Kayanuma vitrites is similar to that between hardness and rank of ordinray Japanese coals, but the former shifts to lower hardness under 90 per cent carbon content and higher hardness over 90 per cent carbon content.It is supposed that Kayanuma vitrites are metamorphosed under the special geological condition, because the coal band of Kayanuma vitrites shifts to the richer hydrogen region than that of ordinary Japanese coals.

    SYNOThe analysis of five commercial fuel additives was carried out by spectrophotometer and X-ray diffractometer.It was found that their main components were copper and sodium.Coking of the coal mixed with five commercial fuel additives or twelve inorganic compounds was made at high temperature.Then, ignitibility, combustibility and reactivity of coke were determined.
    As the results, the followings were revealed:
    (1) The reactivity of coke rises about 20-50% in case of adding commercial fuel additives except one.
    (2) As for ignitability, combustibility and reactivity, six of tested inorganic compounds (CuCl2, PbCl2, SnCl2, V2O5, NaCl, KCl) are effective, bnt the other six (Fe2O3, Ca (OH) 2, MgO, BaCl2 SiO2, ZnO) are retroactive.
    (3) The ignitability, combustibility and reactivity of coke in adding of these inorganic compounds are in proprotion respectively.

    The author studied the effects which carbon residue obtained by Conradson method has on combustion in diesel eugine.As the process, various kinds of heavy oil of different districts and differeut refinery methods are blended to make the test oils of ad-Equate grade.They are used in the test engine, and the results are compared ith wthe percentage of carbon residue.In this case, a new method of evaluating combustion quality and engine test is used.The result in when the percentage of carbon residue is changed with certain base oil and blending ratio, the carbonicions material deposited in combustion chamber changes relatirely, but, in most cases, the esential difference of hydro-carbons has greater effects, as well as sulpher content.
