摘要：The porous alumina as a plate catalytic support was prepared by anodization. Effects of hydration condition on the property of alumina supports were studied. The samples were characterized by XRD, SEM, BET and etc. to illustrate the Al2O3/Al forming mechanism. The results show that the best hydration temperature is 80 degrees C, at which the amorphous alumina can be transformed into AlOOH, and become gamma-Al2O3 after 500 degrees C calcination. Meanwhile, the monoliths catalytic carriers have a superior stability for crystalline structures in the steam atmosphere at high temperature.
