ZEOLITE CONTAINING CATION EXCHANGERS, METHODS FOR PREPARATION, AND USE |
摘要 |
The present invention concerns zeolitic cation exchangers consisting of expanded ceramic, zeolitic pellets with macro- and microporosity, in the form of sintered, light, expanded clay aggregates which are partly transformed to zeolite by means of hydrothermal treatment with an alkaline solution for a period of at least 2 hours at a temperature of between 50 and 300 degrees C. The invention also concerns a procedure for producing said cation exchangers, and applications of the same as ion exchangers and adsorbents.
