Abstract

Here, we report the ZSM-5 synthesis technique using the Solid State Crystallization (SSC) method using natural silica precursor from sugarcane bagasse ash (SCBA). Natural silica was obtained by the extraction process using an alkaline NaOH solution and the formation of silica gel was carried out using HNO3 solution. The synthesis of ZSM-5 begins with the preparation of the aluminosilicate gel by the molar ratio of Si / Al = 4,63, NAOH / Si = 0.229 and H2O / Si = 30 reactants through a low temperature sol-gel process and subsequently evaporated to remove the solvent at room temperature. The dried gel is transferred into the teflon-lined autoclave and crystallized without addition of water and other solvents. The performance of ZSM-5 crystalline growth was observed by changing the temperature and time of synthesis. The results show that ZSM-5 based natural silica was well crystallization after heating at 150 ° C for 48 hours confirmed by XRD data. Compared with conventional hydrothermal, SSC method is an ordinary, economical and environmentally friendly synthesis technique.
