摘要
通过对低稀土超稳分子筛制备过程交换降钠工艺的试验对比,在考察稀土利用率以及物料过滤性能的基础上,筛选出工业化高效的工艺操作。
An industrial and high-efficient process operation was selected through the test comparison of ion exchange and de-sodium technology in the preparation of low rare earth and ultra-stable zeolite based on the investigations of the utilization ratio of rare earth and filtration property of materials.
