【摘要】 在直径为0.08m立式玻璃反应器中,研究了用CCl₄还原UF₆以制备UF₄的过程。试验中把预热到约350℃的UF₆和CCl₄加入反应器,并保持塔壁约500℃,此反应几乎完全在气相中进行。增加反应物给料速率能目视到高温火焰,而且火焰亮度随反应物给料速率变化。维持CCl₄过量,UF₆可基本完全转化。该法被认为是一种适合连续转化低浓缩度UF₆的可行的工艺过程。更多还原

【Abstract】 The reduction of UF6 to UF4 by CC14 in a 0.08 m diameter vertical glass reactor has been studied. In the tests, UF6 and CC14, preheated to about 350> were fed into the reactor and the tower walls were held at about 500?the reaction was taking place almost completely in the gaseous phase.A high temperature flames can be visually observed by increasing in the reactant feed rates, and the brightness of the flame changes with the reactant feed rates. The conversion of UF6 is essentially complete if a CC14 excess is maintained.The method is considered to be an effective process to meet continuous conversing of slightly enriched UF60更多还原
