| Abstract: | This paper describes the synthesis of 4A zeolite with high calcium ion exchange capability, from the raw material of coal-series kaolin through several steps such as calcination activation, glue formation, crystallzation and filtering. Some useful exploration both from theoretical and practical aspects were given, the relationship between each process parameter and the properly of the product was also revealed; thereby a conclusion that the process route for the synthesis of 4A zeolite from coal-series kaolin is proven reasonable and hopeful. |
