ジャーナル フリーDecantation and solvent extraction are applied to remove the solid particles from coal tar. In the production of coal tar pitch for carbon fiber, further treatment such as filtration is necessary in order to remove fine solid particles from coal tar. In this report, change in the filtration resistance was studied by changing filtration temperatures, pressures and pore size of filter. And also, that of the resistance was analyzed with Darcy's equation. These results are summarized as follows.(1) The experimentally obtained filtration curve shows a good agreement with Darcy's equation.(2) No change in the filtration resistance of the cake is found in the different filtration temperatures. This result means that the filtration rate increases at higher temperatures, since the viscosity of tar becomes much lower with the increase of temperature.(3) The filtration resistance of the cake is dependent on the filtration pressure. The cake shows the compressive property.(4) There is no difference in the filtration resistance according to the pore size of the filter.抄録全体を表示PDF形式でダウンロード (890K) -

ジャーナル フリーSorption behavior of ethylene with stage-2 binary GICs (AMC24: AM=K, Rb, Cs), and the structure and thecharacteristics of resulting ternary compounds (AMC24 (C2H4) n) were investigated. The differences of these propertieswere discussed in terms of alkali metal effect. It was confirmed that the easinessof ethylene sorption and the stabilityof resulting ternary compound are in parallel relation, in the order of Cs>Rb>K. In the case of KC24, co-intercalation of ethylene seemed to be doubtful in regards to XRD observations. The ethylene-sorption behavior by AMC24 isconsidered to be mainly controlled on the size of alkali metal ions. The difficulty in preparation of KC24 (C2H4) n maybe due to narrow interlayer space of KC24 and weak K+-C2H4 interaction. In conclusion, CsC24 (C2H4) n was found tobe most stable in air both in its structure and in its high electrical conductivity.抄録全体を表示PDF形式でダウンロード (762K) -

ジャーナル フリーSonication was carried out through the curing process of furan resin by using an ultrasonic homogenizer at thefrequency of 20 kHz and the intensity of 50 W/cm2. Carbonaceous fine particles were added to furan resin to investigate the sedimentation behavior in cured resin. Curing rate of furan resin was accelerated by sonication, which was effectiveto remove out the included larger pores and also to avoid the sedimentation of the particles. The additives weredispersed uniformly in the cured furan resin by sonication. Therefore, it was clarified that the additives were able tobe distributed homogeneously in the furan resin by the ultrasonic treatment.抄録全体を表示PDF形式でダウンロード (2057K) -

ジャーナル フリーFor preparation of metal chloride- and alkali metal-graphite intercalation compounds (GICs), the two-zone method is usually employed. When the experiments are carried out, however, some difficulties should be considered: e. g. corrosive chlorine gas is essential to the two-zone reactor for the greater part of metal chloride-GICs and alkalimetals are reactive with atmospheric moisture. In this report we present some useful techniques for the effective andless dangerous preparation of metal chloride- and alkali metal-GICs.抄録全体を表示PDF形式でダウンロード (721K) -

ジャーナル フリーcountry have been taking policy for all discharge gas except for diesel engine.
Base on the interest of enviromental protections, more energy saving purification technology and to regenerateclean environment and the high level polluting matter elimination technology are needed. On the other hand, theeconomic competition of developing countries by producing goods without concidering to the environment had madeserious environmental pollution . Therefore, Basic theory of energy saving and low cost technology for the plesentenvironment and the prevention of air pollution are requested over the world.
There are a lot of principles for fixation of pollutant emission and its inharmfulity. Large surface area, designedpore distribution and activated carbon with surface functional group are thought to be a main material. It is possibleto construct the basic principle for high level cleaning using low energy by the advanced of material and process design (fixation, contact conversion, and recovery).
In this paper, the feature of carbon fiber with 10-20μm diameter (activated carbon fiber, ACF), the abstractof the manufacturing method, the technical basicity for air cleaning and the future of ACF are introduced.抄録全体を表示PDF形式でダウンロード (1255K) -

ジャーナル フリーSurface charge of activated carbon in aqueous system and its influence on adsorption property was reviewed fromthe viewpoints of electrokinetic potential (ζ potential). Surface charge varies extensively depending on the precursorfor carbon, activation condition and post-treatment. The adsorption of various adsorbates, e. g., dyes and natural organic materials was affected by ζ potential in addition to pysical properties such as pore size and specific surface area of activatedcarbon. These suggest that surface charge plays an important role in activated carbon as an adsorbent in water.抄録全体を表示PDF形式でダウンロード (1178K) -

ジャーナル フリーIt is suspected that nonylphenol and bisphenol A have endocrine-disrupting effects, and a method of their removal is urgently sought. In this study, in order to obtain fundamental data on their removal by activated carbon adsorption, adsorption isotherms were measured. Adsorption data from four commercial activated carbons used for water treatment indicated that the chemicals were very adsorbable even in extremely low concentration.抄録全体を表示PDF形式でダウンロード (259K) -
