Extract

Zeolites-based fluid cracking catalysts are used in petroleum refining. Zeolites are crystalline alumina silicates with a framework based on extensive three-dimensional network of oxygen, and cations which occupy nonframework positions. The distribution of silicon and aluminum atoms within the framework determines many important properties of zeolites, most notably catalytic, absorptive capacity, acidity, stability, etc. For the zeolite scientist, information obtained from the determination of silca:alumina ratio (SAR) and soda:alumina ratio (NAR) during crystallization, dealumination and cationic exchange is important for the optimization of preparative techniques and development of new products.
