Abstract:

Article Preview

Type-A zeolite was synthesized in hydrothermal condition with stellerite obtained from Guangxi. The influences of raw material modification, crystallization temperature, crystallization time and particles’size of stellerites were discussed on preparing zeolite molecular sieve. It is shown that A-type zeolite was synthesized in crystallization time of 6 hours, crystallization temperature of 90-100 °C according to certain proportion with stellerite modified by hydrochloric acid of 15%. The crystallinity of A-type zeolite is 98%, whiteness 95%, average particle size 3.72 µm and more than 90% particles’size are less than 10μm. These meet the zeolite standards of Q / Chalco A021-2004. Type-A zeolite is widely used in detergent industry, petrochemical industry, chemical industry, environmental protection and development of new functional materials fields as it has many excellent performance, such as good ion exchange, adsorption and catalysis, due to its unique crystal structure[1-4]. Because the synthesis of type-A zeolite based on chemical materials costs too much and is also restricted by chemical materials, which can not meet the needs of zeolite application. Therefore, researchers have become focus on preparing type-A zeolite with cheap mineral- materials[5-8]. In this research, we prepared type-A zeolite through Hydrothermal method with stellerites obtained from Guangxi.
