ジャーナル フリーThe North Sea gas field has recently become one of the most active explorational and developmental area in the world.
This paper, the first, outlines the geological and stratigraphical structure of the North Sea area. The second, miceraneous activities taken by countries adjoining the North Sea are mentioned.
The Situation of United Kingdom for exploration and development of the area is also mentioned.
The last, transportation and utilization program of gas in England are outlined.抄録全体を表示PDF形式でダウンロード (1177K) -

ジャーナル フリーThe utilization of zeolites as adsorbents and catalysts in petroleum processing is gaining in industrial importance. The processes using zeolites are presented in petroleum refining, petrochemical and natural gas industry.
Separating n-paraffin from kerosene fraction with zeolite (Molecular sieve 5A) is practiced extensively for production of soft synthetic detergent. The zeolite is also used for sweetening of natural gas and purification of waste hydrogen. The zeolitic cracking catalysts have higher activities and better selectivities than conventional catalysts, it is estimated that at least 50 percent of cracking units is now of zeolitic ones. In hydro-cracking of petroleum fractions and alkylation of benzene with ethylen, zeolitic catalysts are used commercially.抄録全体を表示PDF形式でダウンロード (1148K) -

ジャーナル フリー(1) In a rotary retort (200mm∅×180mm), “Miike coal (50%) and Tagawa senseki (50%) ” and “Yubari coal (80%) and Sunagawa low temperature coke (20%) ” were carbonized at a low temperature with and without passing air stream.
The result of proximate and ultimate analysis, density, blackness of these carbonized samples, absorption amount of basic dyestuff by these samples, and combustion in a rotary retort were discussed.
(2) Hydrogen content of samples were always low and blackness of samples were always high at same carbonization temperature when the samples were carbonized with passing air stream.
It was recognized that low content of hydrogen was caused by oxidation and high blackness of samples was by the difference of physical construction of coke.
(3) There was little difference at same carbonization temperature in the density of these samples and absorption amount of basic dyestuff by them when they were carbonized with and without passing air stream.
It was recognized that little difference in density was by reason of little effect of poly-condensation of coke with and without passing air steam, and little difference in absorption amount of the basic dyestuff was by reason of the thermal decomposition of few amount of the acidic radicals formed by oxidation.
(4) Combution in the rotary retort when carbonization was carried out with pass-ing air steam, was confirmed by discussion of analytical data of gas in the rotary retort and of production amount of tar and gas liquor.抄録全体を表示PDF形式でダウンロード (807K) -

ジャーナル フリーBatch type extraction apparatus in large scale was built to get 2, 9-dimethylpicene from Yubari coal. This apparatus can treat 100 kg of coal ground under 60 mesh. Coal was packed in eight cloth bags and put in the extraction chamber. They were extracted with benzene at about its boiling temperature for 4 days. Then the solution was condensed in the same vaporization chamber and taken out. The condensed solution (about 30l) was filtered and condensed again to 71. After leaving this overnight black precipitates were filtered and recrystalized with toluene to get grey raw 2, 9-dimethylpicene. Average yield of 2, 9-dimethylpicene was about 0.025% of raw coal.
The apparatus worked very well. The apparatus and operation were described in detail.抄録全体を表示PDF形式でダウンロード (486K) -

ジャーナル フリーBituminous coal mixed with ferric oxide was heated at 300, 350, 400 and 450°C and reaction of ferric oxide and the coal was studied from the change of reaction products.
For the coal mixed with ferric oxide, heating loss of coal or tar yield decreased, while evolving gas slightly increased, but functional groups of oxygen of heated residue were not influenced by ferric oxide. On the other hand some of ferric oxide was reduced distinctly to ferrous oxide and metallic iron at the plastic temperature of coal.
From these results, reduction of ferric oxide was deduced principally by de-hydrogenation of active methylene of coal which was supported by model reaction of ferric oxide with some pure organic substances such as tetraline, 9, 10-dihydrophenanthrene, 9, 10-dihydroanthracene and 1-methylnaphthalene, .抄録全体を表示PDF形式でダウンロード (1206K) -
