The supports with secondary building units (SBUs) for zeolite membrane was prepared by MOR zeolite powder using the cold isostatic pressing-solid state sintering method. The propertities of the porous suppport were examined by N2 permeance, open porosity, cross-bending strength, mean pore size and distribution of pore size, the coefficient of thermal expansion, X-ray diffraction (XRD), Raman spectroscopy and scanning electron microscopy (SEM). The results were that with the rising of sintered temperature and the extending of calcination holding time, N2 permeance and open porosity decreased, but the cross-bending strength increased. The mean pore size became big with the sintered temperature increasing and the distribution of pore size was narrow with a narrow distribution of starting material particle size. The SBUs of 4, 5 and 8 membrane ring of MOR were kept in the supports. The MOR membrane prepared on the support had good thermostability because of the SBUs and low coefficient of thermal expansion (at the level of 10-6 ℃-1).
