Abstract

ZSM-5 was crystallized at low temperature and atmospheric pressure using reflux unit. The overall molar composition used in this study was $7.83Na_2O-0.25Al_2O_3-100SiO_2-xTPABr-yH_2O$ where x is 1 and 3 mol, and y is 3000 mol, 3500 mol, and 4000 mol. $2^3$ factorial experiments were performed with the results of kinetics studies, showing $Na_2O$, TPABr, and $H_2O$ as main factors. The result suggested that the concentration of $H_2O$ is the most important. The morphology of final product was very uniform showing well-defined crystals with BET surface area of ca. $410m^2/g$.
