ジャーナル フリーRecently radioisotopes have been widely applied for the quantitative and qualitive analyses of gaseous, liquid and solid fuels. Among many ways of analyses, the author explains X-, β-and γ-ray absorption, nuclear absorption, and fluorescent X-ray methods as well as the rapid analysis of coal ash by means of X, β and γ rays, radioactivation analysis and the analysis of fuel gas by high sensitive gaschromatograph in which RI is used as detectors.
Some applications are shown as determination and ultimate analysis of H and H/C in fuels, analysis of S, Cl and heavy elements in petroleum hydrocarbons, analysis of Ni and V in heavy oil, determination of tetraethyl-lead in gasoline, determination of H2 in heavy oil and calculation of its calorific value, determination of Cu, Fe and V in crudes and liquid fuels, and analysis of C and O2 is coal ash and coal. The results are obtainable within the accuracy of from 0.1 to 0.01%.抄録全体を表示PDF形式でダウンロード (1658K) -

ジャーナル フリーThis paper comprehensively reviews the applications of radioisotopes in the petroleum industry in Japan and briefly reviews the recent developments in this field in other countries.
In Japan, radioisotopes as tracers or sealed sources have been applied to the refinery plants to study refining processes such as fluid catalitic cracking, distillation and blending. Radioisotopes have also being employed in both fuel and lubricating oil research such as engine wear, lubricating oil consumption etc. However, radioisotopes have not been widely applied to the analysis except the determination of sulfur content in oils by means of sulfur meter. The applications in maintenance and process control in refineries are rare in Japan in contrast to many applications in other countries.
To our regret, the present use of radioisotopes in the petroleum industry in Japan is not so active as in other countries. The growing potentiality in supply of domestic radioisotopes and technology of atomic energy will greatly stimulate the wide application in the petroleum industry in Japan in the near future.抄録全体を表示PDF形式でダウンロード (1424K) -

ジャーナル フリーCoal assumes an important role as energy souces along with hydraulic power in our country. In order to supply energy at low cost each coal mining company has tried to carry out the rationalization of industry in many respects.
Hereafter it is necessary for us not only to promote the mechanized extraction of coal, but also to study positively the new method of extraction of coal namely, “the underground gasification process” and especially to establish the new method which is suitable for the conditions of our country.
Based on the tests which we have made in our coal field, we have made a plan of this enterprise and made preliminary calculation of the cost.
According to this plan the cost of underground gasificated gas, in generating electrical energy, will make great promise in enhancing coal's status.
We would like to promote this research with good hopes.抄録全体を表示PDF形式でダウンロード (1489K) -

ジャーナル フリーThe signal of electron spin resonance of Yubari coal under vacuum was found to consist of two components as a result of analysis for the shape variation of derivative curve caused by saturation effect. The method of separating broad and narrow components from the derivative curve was described.
For the narrow component, the peak-to-peak line width (ΔH″msl) and the spin center concentration (N″) show almost no change up to HTT about 400°Cand the narrow component disappears in the range of HTT about400-450°C.On the other hand, for the broad component, both the peak-to-peak line width (ΔH′msl) and the line width (ΔH′) decrease above HTT about400°C, and the spin center concentration (N′) increases up to HTT500°C.
All the narrow components, up to HTT400°C, shown under vacuum seem to disappear under air.抄録全体を表示PDF形式でダウンロード (991K) -
