ジャーナル フリーNowadays the problem of air pollution has come to be very trouble gome problem in our daily life and many people are doing the hest to abate and control air pollution.
In this report, the auther described mainly the problem of atmospheirc diffusion in air pollution
That is, chapter 1 and 2 states the general situation of the atmospheric diffusion and the control of air pollution
Chapter 3 and 4 states the equation of atmospheric diffusion and the effect of stack.
Chapter 5 and 6 states the wind tunnel tests and the survey methods of air pollution.
Chapter 7 states the conclusion.抄録全体を表示PDF形式でダウンロード (1761K) -

ジャーナル フリーIn parallel with the increase in the national income and in the living standard, demand of town gas for the past decade has greatly been elevated. Nevertheless, by the advent of LPG, it was surpassed by LPG in demand houses. Town gas manufacturers are devoting toward the rationalization in supply such as by applying conversion of raw material, calorie-up, high pressure supply system. It will be thus expected that town gas and LPG will take the way of coexistence and coprosperity in towns and in farm villages, respectively.
Seeing the changing pattern of raw material supply system, solid fuel was converted to liquid one. Recently heavy and light oils and kerosene have been replaced by crude oil, naphtha and LPG in view of price. Consequently, the newly-established gasifiers are mainly of oil gasification type.抄録全体を表示PDF形式でダウンロード (961K) -
酸化炭のカルボキシル基の挙動西田 清二, 山根 守, 小川 毅一, 宮下 功1965 年 44 巻 9 号 p. 626-632

ジャーナル フリーThe properties of carboxyl groups in the oxidized coals obtained from Tenpoku-Fujita (C: 70.9%a.m.f.) and Sumiyoshi (C: 76.2%a.m.f.) coals by HNO3 treatment were studied by using the methods of ion exchange with Ca (CH3COO) 2 aq.sol.and infrared absorption spectra.
Carboxyl groups in oxidized Fujita coals were subjected to Ca (CH3COO) 2 aq.sol.exchange completely under N2 atmosphere 18°C, 20hrs. While oxidized Sumiyoshi coals had later exchange rate than Fujita's, and yet exchange reaction proceeded after 7 days. But the exchange rate of the humic acid extracted from oxidized Sumiyoshi coal did not vary significantly from Fujita humic acid.
These results were accessible by assuming a rate-determing diffusion of Ca++ ion into oxidized coals. In the case of treating the oxidized coals in much amount of Ca (CH3COO) 2 aq. sol., it could be seen that other acidic groups (probably phenolic) exchanged with Ca (CH3COO) 2. When the oxidized coals were heated in Ca (CH3COO) 2 aq. sol., a remarkable increase of exchange capacities was seen. These increase may be reduced to the action of CO2 given by decarboxylation and newly produced carboxyl groups.抄録全体を表示PDF形式でダウンロード (851K) -

ジャーナル フリーMineral composition of some Japanese and foreign coal samples and specific gravity fraction of these samples was studied by means of X-ray analysis. Minerals identified from X-ray diffraction patterns of these coal smples were quartz, calcite, dolomite, siderite, pyrite and clay minerals such as kaolin mineral, illite and montmorillonite. These clay minerals were identified from the behaviour of the diffraction profile after treatment with glycerol or hydrochloric acid. Calibration curves were made up from the pure standard minerals, using fluorite as internal standard, and quantitative estimation was done for quartz, calcite, dolomite, siderite, kaolin mineral and pyrite. Each mineral could be detected at least about 0.5% content in the sample. The mean deviation of the estimated value was about several percent for quartz and about 10-15 percent for carbonate mineral, kaolin mineral and pyrite. Quartz was generally found in all samples. Calcite and kaolin minerals were also dominant in most samples.抄録全体を表示PDF形式でダウンロード (876K) -
