The textural properties of MCM-48,Mg-MCM-48-x(x=0.01,0.02,0.03)and Zr-MCM-48-x(x=0.02,0.04,0.06)are listed in Table 1.In comparison with MCM-48,the specific surface area and pore volume of all samples decreased with an increasing content of incorporated metal(Mg or Zr).This could be probably attributed to the loss of the lattice ordering of MCM-48 framework resulted from the increase in the content of incorporated metal.The degree for loss of the lattice ordering of MCM-48 framework would become greater with an increasing incorporated metal content,and thus the specific surface area and pore volume of the samples could become smaller with the increase in the incorporated metal content.
