Mesostructured hydrated alumina - surfactant composite compositions and mesostructured transition alumina compositions derived therefrom

摘要

Mesostructured crystalline alumina compositions with both low angle and wide angle x-ray diffraction patterns and a process for the preparation thereof using a surfactant which is preferably an organic amine compound or a quaternary ammonium compound or a combination of both as a porogen are described. The compositions are useful as catalysts and as absorbents.
