By means of a linear sweep voltammetry, cyclic voltammetry and chronopotentiometry, the electrolytic reduction uranium oxide has been studied to establish mechanisms, which are based on simultaneous Li2O electrowinning, formation electrolysis lithium uranate. From voltammograms, potentials were obtained. chronopotentiometries results was reduced metal through mechanisms showing more than 99% conversion. For verification feasibility, basic data obtained from experiments characteristics closed...
The Advanced Spent Fuel Conditioning Process (ACP) has been proposed and developed by the Korea Atomic Energy Research Institute (KAERI) to treat oxide spent fuels (SFs) from light water reactors reduce volume, heat load, radiotoxicity of processed SFs. In ACP, an electrochemical reduction process developed, electroreducer with a maximum 20 kg/batch scale installed in KAERI ACP facility. this study, runs were carried out 10 SIMFUEL at 923 K under current controlled conditions.The processes...
A metallothermic reduction technique was adopted to reduce rare earth oxides in a molten LiCl. reducing agent of Li supplied the system by dissolving excess amount metal on separated section reactor. The extents were measured analyzing Li2O which is product chemical reactions. Nine kinds form RE2O3 partially reduced corresponding metals until concentrations reached certain critical values for each reaction. activity coefficients evaluated based concentrations. These experimental results gave...
이온성 액체는 일반적으로 거대 헤테로 고리 양이온과 무기 음이온으로 이루어진 염으로, 상온에서 액체로 존재한다. 따라서 액체의 물성은 음이온의 종류, 알킬기의 수에 영향을 받으므로 그 조합에 의해 액체 각각의 물성이 달라진다. 또한 비휘발성, 열적 안정성, 넓은 전기 화학적 범위를 가지므로 기존의 유기용매를 대체할 주목할 만한 청정 용매(Green solvent)이다. 본 연구에서는 1-Butyl-3-methylimidazolium bromide ([BMIM][Br]), 1-butyl-3-methylimidazolium Chloride ([BMIM][Cl]), iodide ([BMIM][I]) 그리고 tetrafluoroborate ([BMIM][<TEX>$BF_4$</TEX>])을 합성하였으며, 중 [BMIM][Br], [BMIM][I], [BMIM][<TEX>$BF_4$</TEX>]의 밀도, 점도, 굴절률, 열용량과 이온전도도를 293.2~323.2 K의 온도범위에서...
Choline chloride (ChCl) is a well-known material forming deep eutectic solvents (DESs) when mixed with hydrogen bonding donor (HBD). The potential applicability of DES systems wide for replacing ionic liquids at relatively low cost. Therefore, the application to chemical processes necessitates reliable data properties. In this work, thermal behaviors two ChCl-based (ChCl+urea and ChCl+1,3-dimethylurea) were investigated by using differential scanning calorimeter. Crystalline as well...
