Abstract

ZSM-5 zeolites with different Si/Al ratios were synthesized by hydrothermal

in situ

method. The effect of Si/Al ratio on the structure and hydrophobicity of ZSM-5 was studied. The adsorption performance of ZSM-5 zeolites for toluene was investigated on a dynamic adsorption experimental device

and the adsorption isotherm equation of toluene on hydrophobic ZSM-5 was studied. The results show that the high-silicon ZSM-5 has good hydrophobicity

and its static water adsorption capacity is 0.014 g·g

and the temperature of 35℃

the breakthrough adsorption capacity of the synthesized ZSM-5 for toluene

is 0.041 g·g
