Judul	:	Effect of H2O/SiO2 Molar Ratio on Direct Synthesis of ZSM-5 from Bangka’s Kaolin Without Pretreatment
Abstrak	:	The influence of the molar ratio H2O/SiO2 in the synthesis directly from Bangka Belitung’s Kaolin has been studied by performing synthesis of ZSM-5 with a variation of the molar ratio H2O/SiO2 is different at 15, 25, 30, and 35. Weighing 3.980 g Bangka’s kaolin are added other material so obtained molar composition 10Na2O: 120SiO2: 2Al2O3: 1800-4200H2O, and 1% of silicalite seed, subsequent hydrothermal proccess of 175°C for 24 hours. The result of solids were analyzed by X- ray diffraction (XRD) and Fourier Transform Infrared (FTIR) and SEM EDX to analyzed morphology of ZSM-5 crystal. The synthesis of ZSM-5 was directly optimum with molar ratio H2O/SiO2 of 30 having the highest cristalinity and largest crystal size of 59.44% and 3.795 μm, respectively. Keywords: Kaolin, direct synthesis, ZSM-5, hydrothermal, zeolite
