ABSTRACT:
High pore volume alumina materials which are particularly effective catalyst supports are prepared by treating a calcined alumina with an organic acid such as ethanedioic acid. The acid treatment changes the pore structure of the alumina and particularly increases the macroporosity of the alumina.
