Pore structurecharacterizebyN2isothermal adsorption-desorption is showed in Table 1.As shown in Table 1，specific surface area，pore volume and average pore diameter of the HZSM-5 zeolite catalyst are larger than that of Zn-HZSM-5 zeolite catalyst.With the increase of Zn content，specific surface area，pore volume and average pore diameter of Zn-HZSM-5zeolite catalysts decrease，probably because the atomic radius of Zn is larger than Si and Al.When Zn enters into the framework of zeolite through in-situ hydrothermal synthesis，the pore volume and pore size of zeolite decrease[24].
