• Development of the latent heat storage materials with the high fluidity, HARANO Azuchi, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Challenging Exploratory Research, Grant-in-Aid for Challenging Exploratory Research, Gunma University, 01 Apr. 2012, 31 Mar. 2014, In order to use the exhaust heat and the solar heat for the heating and the hot water supply inside house, it is necessary to develop the latent heat storage material which has the good flow characteristics into pipe from outside to inside. In this study we investigated the possibilities of latent heat storage materials through carrying out the three following experiments. (1) Development of highly-concentrated slurry of latent heat storage materials, (2) Examination of heat storage materials using the liquid-solid-liquid phase change of nitrate, (3) Examination of sodium chloride as an absorber of absorption heat pumps. In the experiments of (2) and (3), there was a problem about the sudden fluidity drops of accompanying crystallization of heat storage material. But the solution of sodium sulfate 10 hydrates which added the surfactant (1), had the high fluidity for even under the condition of highly-concentrated slurry., 24651070

• Synthesis of hydrogen peroxide using atomization of fine droplet into plasma, HARANO Azuchi; OTA Tomohisa; WATANABE Tomohide; SATO Masayuki, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (B), Grant-in-Aid for Scientific Research (B), Gunma University, 2000, 2003, A fundamental study of SO_2 removal using the fine droplets containing hydrogen peroxide is presented. The aqueous fine droplets ranging from 100μm to 300μm were produced into Pyrex glass reactor by electrostatic spray consists of the grounded capillary with 100μm in inner diameter and the circular stainless net which is applied high voltage. Improvement of SO_2 removal efficiencies were observed via atomization of aqueous droplets of 200μm or less in diameter. Remarkable enhancements of SO_2 removal were observed by the addition of hydrogen peroxide which was promoted the SO_2 absorption into fine droplets following the oxidative reaction of sulfite ions in liquid phase. The high removal efficiencies about 80% were obtained at equivalent point of SO_2 and H_2O_2 within 0.03sec contact time of droplets with SO_2 gas through the amount of water consumed in this experiment is about one tenth of that of the conventional wet desulfurization processes. This process is expected to reduce the amount of water very much and as a consequence, the total working cost could be decrease comparing with that of the existing similar wet SO_2 removal processes. Simple numerical calculation of SO_2 absorption into droplet following oxidative reaction with H_2O_2 was performed for analysis of experimental results. Even though there are some minor differences between experimental results and calculation, a good agreement is approximately obtained., 12558066

• Degradation and removal of environmental contaminants in water using high energy electrons and radicals, SATO Masayuki; MIURA Masahiko; HARANO Azuchi; OHSHIMA Takayuki, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (B), Grant-in-Aid for Scientific Research (B), Gunma University, 1999, 2001, The following results were obtained as the research from 1999 to 2001 fiscal years. (1) In low conductive water, two-step breakdown in the development of the total electrical breakdown in water were observed. The existence of this regime was limited by the water conductivity, applied voltage, and capacitance of the storage capacitor. The distortion of the electric field at the head and an increase of the leader channel resistance due to accumulation of the electrostatic charge on inside wall of the gaseous channel were most likely two mechanisms effective in the transient regime. (2) With changing electrode gap distance, three discharge modes were observed, i.e. streamer, spark with streamer, and spark discharges. The formation of active species and ultraviolet radiation, which are important chemical species and physical effects for degradation of organic pollutants were strongly dependent on the discharge mode. (3) It was found that the discharge modes, gas bubbling and chemical additives affected the degradation of phenol and dyes. In the case of streamer discharge, hydroxyl radicals were considered to be the dominant process. In the case of spark and spark with streamer discharge mode, the other physical effects such as shockwave and ultraviolet radiation may take place on the degradation process besides the hydroxyl radicals. (4) A large volume streamer corona discharge was generated around the ring electrode, and the discharge formation was greatly dependent on the electrode geometry, polarity and the water conductivity. It was found that the insulation technique of the ring electrode was the most important factor for decrease streamer initiation voltage., 11555205

• Investigate of O-emission mechanism from YSZ/metal surface into gas phase, SADAKATA Masayoshi; HARANO Azuchi; OKUBO Tatsuya, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (B), Grant-in-Aid for Scientific Research (B), THE UNIVERSITY OF TOKYO, 1996, 1997, Radical reactions play important roles in combustion process and catalytic process. However, there are few methods, which produce radicals effectively as well as selectively. We approach this problem in the view of developing new radicals generator. Yttria Stabilized Zirconia (YSZ) is often used as an oxygen sensor and/or a solid electrolyte because of its oxygen anion (0^2) conducting characteristics. Desorption of oxygen anion radicals from the YSZ can be expected in a low electric field of 100- 200V/cm at around 400-5000ﾟC. The main purpose of our research is to determine the amount of oxygen species and estimate the rate-determining step by use of QMS (Quadrupole mass spectroscopy) . Only 0 was detected as oxygen anion species. Experimental results showed that the desorption process of oxygen anion species from the anode electrode of the YSZ was most dominant factor in our process. The activation energy of oxygen anion desorption was estimated to be 80-lOOkJ/mol in the case that 100-200V/cm was applied. This research also focus on metal catalysts(Ag, Pt) which favor oxygen adsorption, because the low electric field of lOOV/cm may release the adsorbed oxygen as oxygen anion radicals. A mass spectrum of anion species contained both MN=(O) and MN=32 (0_2) . Our results indicate that the metal catalysts have the possibility of generating oxygen anion radicals, 08455352

• DEVELOPMENT OF A NOVEL TECHNOLOGY FOR AIR POLLUTION CONTROL BY USING ELECTROSPRAY METHOD, HARANO Azuchi; HASHIMOTO Mitsuo; SATO Masayuki, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (A), Grant-in-Aid for Scientific Research (A), GUNMA UNIVERSITY, 1996, 1997, In this study, we proposed the novel De-NOx technologies by using the fine water droplets which produced by electrospray method. First one is the enhancement of thermal De-NOx reaction at low temperature by atomization of phenol and/or ammonia solution. We obtained the following results. (1) By coexisting ammonia with phenol aqueous solution, reduction of NO was proceeded at the range of lower temperature, 650-750ﾟC,but was restrained at the range of higher temperature, 750-850ﾟC. (2) By injecting phenol/ammonia aqueous solution as droplet by electrospray method, the markedly improvement of NO reduction was confirmed. About 30% of nitrogen monoxide was reduced at 650ﾟC (twice as much as the case of pre-vaporized solution), and about 50% at 700ﾟC in the following condition, NO 388ppm, O2 4%, NH_3400ppm, phenol 102ppm, H_2O6.4%, N_2 balance, residence time 1.5-1.8sec. (3) As a result of the measurement of CO,CO_2 in outlet gas, we could see more CO concentration at low temperature, 600-650ﾟC.So phenol seems to be decomposed by adding sprayd solutions. Second, the effects of the atomization of droplets into corona discharge reactor on the NOx reduction were examined and have obtained the following results. (1) The efficiency of NOx removal was improved via atomization of fine water droplets into the discharge plasma. (2) Decreasing the mean diameter of droplets, which were injected in the corona discharge, the De-NOx efficiency improved. Especially, we obtained the maximum De-NOx efficiency by using nebulizer. (3) The effect of pH on the De-NOx efficiency was investigated. The efficiency of De-NOx was improved both side of pH5.0. (4) NOx reduction was improved by the addition of H_2O_2. The amount of NO reduction was in the case of H_2O_2 was 1.5 times that of water droplets. (5) The necessary amount of water of this technology are less than that of conventional wet De-NOx process by a factor of about 1/100., 08555182

The ultra fine particles generating from copper rod by laser abrasion was used as samples. The sample particles were observed by scanning electron microscopy and there were distributed from 2nm to 20 nm. The developed analyzer could be measured more than 5 nm particles and it was found that 50 % (weight) of sample particles were aggregated 4 pieces of 5 nm primary particle. The shapes of particles generating from laser abrasion were affected by laser pulse mode., 07555233

• Molecular Sieve Sensor for Pollutants Detection at Elevated Temperat, OKUBO Tatsuya; HARANO Azuchi, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (A), Grant-in-Aid for Scientific Research (A), The University of Tokyo, 1995, 1996, The aim of this project is to develop NOx and SO2 sensors selective at elevated temperature by molecular sieving zeolite film formed on quartz substrates. These sensors are useful to detect the exhaust gas from boiler, furnace engine...ets., and the information can be feeded back to the combustion system. Such a control contributes the human being in view of energy saving and environmental protection. ZSM-5 film was formed on quartz substrate. The substrate was placed in an autoclave where hydrothermal reaction proceeded. We examined the influence of TEOS (Si source) and water concentrations, and the type of structure directing agents. The products were characterized by XRD and SEM which were purchased by this budget. The synthesis condition to obtain oriented film and tailored crystal size was found. A sensor system was fabricated on Au-Cr electrode on quartz. Sensor testing system controled by microcomputer was constructed. After removing the organic structure directing agent by burning, ion-exchange of Na with Cu was performed. This sensor was sensitive to NOx at 100ﾟC. In addiion, we studied the synthesis condition for Zeolite Y,and fould the condition to synthesize Y as sigle phase. SO2 was was detected at 150ﾟC., 07555543

• Basic study of High Efficiency Formation of O^- Anion Radical, SADAKATA Masayoshi; HARANO Azuchi; OKUBO Tatsuya, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for General Scientific Research (B), Grant-in-Aid for General Scientific Research (B), University of Tokyo, 1994, 1995, The chemistry of an atomic oxygen radical anion (O^-) is interesting both from a basic and an application points of view. On the basic side, reactions of O^- are important in the field of an ionospheric chemistry. O^- also cannot be neglected in the field of a combustion and plasma chemistry. On the application side, O^- is a key reagent ion for the chemical ionization mass spectroscopy. O^- is as also useful for the synthesis of negative ion of organic intermediate speies which is appropriate for the study of the structure and characteristics of an organic intermediate. In future, O^- will be used in the CVD (Chemical Vapor Deposition) technology and also in the control technology of air pollution like NO,SO_2 and CO since O^- is a strong oxidizing agent even at the room temperature. In spite of these pieces of importance of O^-, the chemistry of O^- has not been developed significantly so far. One of the reason is that an easy and convenient production method of O^- in the gas phase has not been found in the past. In our study, we discovered that O^- was that ejected into the gas from the electrods surface of a solid electrolyte by applying a low level DC voltage between a solid electrolyte and a space electrode. An experimental apparatus was simply designed to have a space electrode and a solid electrolyte that serves as an oxygen ion conductor. By applying DC voltage of about 50V/cm between the electrodes, ion current was observed. Contents of ion current of 100-200nA was identified by Q-MASS (mass analyzer with a quadrupole) modified for anions. Electrons and O^- were clearly recognized from the mass spectrum., 06453094
