Abstract

Alumina and aluminophosphate (AP) with Al/P ratio of 6 were subjected to hydrothermal treatment at 750 ° C for up to 48 h. The results indicate that AP had a higher hydrothermal stability than the γ-alumina. The pore size distribution and surface area of AP did not change much under hydrothermal conditions. The pore size distribution of alumina, on the other hand, shifted toward larger pore diameter accompaning with decreasing surface area upon deactivation.
