MTT zeolites with different particle size and acidity were synthesized and their catalytic properties were investigated. In this research, TMPD (N, N, N', N'-Tetramethyl-1, 3-diaminopropane) was used as the structure directing agent. MTT zeolite was prepared by hydrothermal synthesis method of gel composition with 1.0 SiO2 : 2.0 NaOH : x(=0.5 ~ 1.5) NaAlO2 : 624 H2O: 30 TMPD at 160 °C for 4 days and the particle size and acidity were controlled by NaAlO2 concentration. Physicochemical properties of the catalyst were investigated by XRD, SEM, N2 adsorption and NH3-TPD. |
