THE EFFECT OF SOME VARIABLES AND PARAMETERS USED IN THE SYNTHESIS OF FAUJASITE Na-X

Abstract

Synthetic zeolites have found several industrial applications as components in heterogeneous catalysts due to its highly regular structure and micropores which have regular dimensions and high specific surface area. However, in many of the petrochemical applications, microporous structure imposes limitations on the diffusion of molecules of reactants and products and becomes a problem. Much research effort has been done in the synthesis of other zeolitic structures with wider micropores diameters or structures having mixed micro and mesoporous. In this study, an experimental design based on the Placket & Burman statistical method was done with the purpose of select variables that has the larger effects on the synthesis of zeolite of type faujasita (FAU-X) with low molar SiO2/Al2O3. After establish the best conditions the effect of the introduction of funcionalized nano-sized carbon particles in the generation of mesoporous structures was verified.
