Abstract:
Described is a novel amorphous silica-alumina composition having a high ratio of pore volume contained in large pores to pore volume contained in medium to small pores. The amorphous silica-alumina composition also may have the characteristic of a strong aluminum-NMR penta-coordinated peak representing greater than 30% of the total aluminum and a method of making such novel amorphous silica-alumina composition using a pH swing preparation method.
