Abstract

Abstract:

A series of ZSM-5 zeolite were hydrothermally synthesized by using the double template system of n-butylamine and ZSM-5 crystal seed.The influence of content of seed and n-butylamine,and crystallication process on the physicochemical properties,pore structure and morphology of obtained zeolites were investigated.The obtained zeolites were subjected to X-ray diffraction（XRD）,N₂ adsorption-desorption and scanning electron microscopy（SEM） characterization analysis.The analysis results showed that the obtained material was aggregated nano-sized ZSM-5 zeolite with ternary pore structure,and n-butylamine and seed crystals had a synergistic effect in the synthesis process.Under the synthesis conditions of n（n-butyla-mine）/n（SiO₂）=0.26,seed addition amount of 3%（mass fraction） and crystallization at 120 ℃ for 24 h and then at 170 ℃ for 48 h,the specific surface area and external surface area were 364 m²/g and 59 m²/g,respectively.

Key words: aggregated nano-sized ZSM-5 zeolites, n-butylamine, seed, synergistic effect
