【摘要】 本文主要研究了如何从合成氨废催化剂中回收氢氧化铝,重新制成氧化铝载体。探讨了浸取时间对氢氧化铝、碳酸钠回收的影响,分析了二氧化碳流量、终点pH值等因素对制成拟薄水铝石的影响。拟薄水铝石经高温加热脱水后可生成所需的活性氧化铝。本实验方法生产活性氧化铝的成本低,简单易行。更多还原

【Abstract】 This paper mainly studied how to recycle Al（OH）₃ from waste catalysts of synthetic ammonia and how to form Al₂O₃ again. What′s more,it discussed the influence on the recycling Al（OH）₃ and Na₂CO₃,and analysed the influence on the pseudoboehm of the flux of CO₂ and ending PH value,etc. Active Al₂O₃ products were obtained by calcunating pseudoboehm items at elevated temperature. The preparation method in this experiment of producing active Al₂O₃ is simple and economical.更多还原
