ジャーナル フリーAs SO2 nuisance has become a large social problem, it is urgently requested to develope the desulfurization technique applicable to the present conditions in Japan.
From this stand point, the several points are discussed in this review based on recent literature on resid hydro-desulfurization and researches carried out at Research & Development Association of Resid Hydro-Desulfurization, mainly on the fixed bed catalysts:
1. structures of catalysts quite effective to desulfurize materials containing metal-complexes, asphaltens etc.
2. poisoning materials of catalysts. 3. status of poisened catalysts.
Hydrogen consumption and material balance which are important factors to evaluate the performance of catalysts are also described.抄録全体を表示PDF形式でダウンロード (2308K) -

ジャーナル フリーIn Japan, water pollution problems become very important for the petroleum industry.
This report refers to the present statue of wastes water treatment methods which are applied at Japanese refineries, and also explains about many regulations which are put in force by Japanese local governments.
In last chapter, the authors opinions for future problems of waste water pollution are described.抄録全体を表示PDF形式でダウンロード (1342K) -

ジャーナル フリーOn the preceding report, the anthor introduced the experimental equation of evaporation velocity coefficient on the process of stationary evaporation about the motor gasoline and the light diesel oil, but on this paper elucidated that was able to gain the equation of the same relation about the heavy fuel oil.
(1) Introduced the rate of linear evaporation from the evaporation velocity equation about the former of stationary evaporation and gained the evaporation velocity coefficients k and k″. Experimental equations of k and k″ were introduced as the function of the furnace temperature θg and initial weight Wf0 of oil.
(2) The rate of evaporation was expressed to (We/Wf0) /A=k′logt for the same furnace temperature independent of the initial weights of oil about the latter of stationary evaporation for all fuel oils, and the evaporation velocity coefficient k′ was constant.
Where We: weight of evaporation (mg)
A: area of evaporation (cm2)
t: time (min)

ジャーナル フリーIn order to examine the effect of solvent-extraction and preheating-treatment upon the dilatation of coal, the following samples were prepared for four Japanese coals (Oyubari 85.9% C, Oshima 84.9% C, Hashima 86.4% C and Eri 86.2% C): (1) coals extracted with pyridine at 10, 30 and 50°C, (2) coals extracted with benzene at 150°C, (3) coals preheated at 300, 350 and 400°C, (4) preheating coals extracted with chloroform.
There is a statistical linear relation between the dilatation of parent coals and their pretreating coals and their volatile matter. And the better linear relation exists between the dilatation of them and the weight loss heating them up to 400°C under 3mmHg (except for Eri coal, because of their small dilatation).
There is nearly linear relation between the dilatation of sample (1) and the extraction yield, the more extracted, the smaller swelling becomes. But the relation between the benzene extraction yield and the dilatation of the residue does not agree with the relation in the case of the pyridine extraction.
When preheating temperature is higher, the dilatation of preheated coal becomes lower. For the same coal sample the relation between the swelling of the sample (3) and chloroform-extraction yield is linear (except for Eri coal). These results may be explained by the extract flowing out of the interior of coal particle to the surface by preheating.
It seems that the condensable gas (tar) produced at the softening temperature range is reponsible to the dilatation of coal, but the non-condensable gas has little affect on the dilatation.抄録全体を表示PDF形式でダウンロード (1348K) -

ジャーナル フリーWhen many kinds of petroleum products of various companies aresent serially through a pipe, the most serious problem is contamination.
In order to reduce the amount of contamination two methods are used; one is a turbulent flow, the other is to use a mechanical separator like a sphere.
Where the method of “a turbulent flow” is used contamination is caused by axial mixing which may be considered as a diffusion mechanism governed by Fick's Law. On the other hand, where the method of “using a sphere” is used, contamination is caused by the “flow back” across a sphere.
The amount of the “flow back” must be about 0.02-0.04 percent of the total volume displaced.
According to the above assumption, this report presents the amount of contamination which is expected to occur in real pipelines, comparison of the two methods, the relation between the final amount of contamination and the number of spheres, their spacing and initial contamination which has occurred at a starting station.抄録全体を表示PDF形式でダウンロード (1186K) -
