| 摘 要： | 采用库仑法全自动碳氢元素分析仪,建立了一种催化裂化催化剂中微量碳含量的分析方法。样品经高温燃烧,碳生成二氧化碳,二氧化碳再与氢氧化锂反应生成相应的水,将水送入涂有五氧化二磷的电解池电解,测量电解所消耗的电量,依照法拉第电解定律计算出样品中的碳含量。实验证明,该分析方法重复性好,准确度高,检测限低,能够满足催化装置上的催化剂分析需要,对实际生产具有指导意义。

| Abstract: | An analytical method was developed for determination of micro content carbon in catalytic cracking catalyst by using automatic carbon and hydrogen element analyzer.The sample was conbusted in a high-temperature furnace,and the carbon element was changed into carbon dioxide,which was reacted with LiOH to produce water.The water produced was sent into an electrolytic cell.According to Faraday's law,the carbon content in the sample can be calculated with the quantity of electricity consumed in the electrolysis... |
