摘要：
This invention relates to a process for the preparation of anionic clay and boehmite-containing compositions. These compositions may also contain unreacted trivalent metal source and/or divalent metal source. The process involves subjecting a precursor mixture comprising a divalent metal source and a trivalent metal source to at least two aging steps, wherein at least once between two aging steps an aluminum source is added. An advantage of the invention is that the crystallinity of the boehmite in the composition can be tuned.
