چکیده مقاله:

In this study, the effects of crystallization temperature, crystallization time, and pH value on the textural properties of synthetic ZSM-۵ were investigated by the orthogonal test method. Furthermore, the effects of ZSM-۵ catalysts synthesized under different preparation conditions on their reactivity during catalytic cracking were evaluated. Moreover, the results have shown that the three factors that affect the ZSM-۵ synthesis are in the following order: crystallization temperature > crystallization time > pH value. In addition, the optimal conditions for synthesizing ZSM-۵ catalysts were crystallization temperature of ۱۷۰ °C, crystallization time of ۴۸ h, and pH of ۱۱. Furthermore, under these conditions, the specific surface area, pore-volume, and acidity of the synthetic zeolite were moderate, and the hydrothermal stability was ideal. Finally, when the optimal conditions were applied to the catalytic cleavage of n-hexane, the synthesized zeolite exhibited good activity and stability.
