عنوان انگلیسی Effects of ZSM-5 Preparation Conditions on Textural Properties and Catalytic Cracking of n-Hexane
چکیده انگلیسی مقاله In this study, the effects of crystallization temperature, crystallization time, and pH value on the textural properties of synthetic ZSM-5 were investigated by the orthogonal test method. Furthermore, the effects of ZSM-5 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-5 synthesis are in the following order: crystallization temperature > crystallization time > pH value. In addition, the optimal conditions for synthesizing ZSM-5 catalysts were crystallization temperature of 170 °C, crystallization time of 48 h, and pH of 11. 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.
