    摘要： Process for the preparation of a metal-containing composition, which process comprises the steps of (a) calcining a physical mixture of an anionic clay and a metal additive at a temperature between 200 and 800° C., and (b) rehydrating the calcined product of step a). This process allows the use of insoluble metal additives. It does not require the use of soluble metal additives, which has economic and environmental advantages.

    摘要： The present invention is directed to a process for the preparation of crystalline anionic clay-containing bodies from sources comprising a trivalent metal source and a divalent metal source comprising the steps of: a) preparing a precursor mixture containing a liquid, a divalent metal source and/or a trivalent metal source, at least one of them being insoluble in the liquid; b) shaping the precursor mixture to obtain shaped bodies; c) optionally thermally treating the shaped bodies; and d) aging the shaped bodies to obtain crystalline anionic clay-containing bodies; with the proviso that if no divalent or trivalent metal source is present in the precursor mixture of step a), such source is added to the shaped bodies after shaping step b) and before aging step d); and with the further proviso that the combined use of an aluminium source as the trivalent metal source and a magnesium source as the divalent metal source is excluded. The quintessence of the present invention is that the major part of the final amount of anionic clay is formed after shaping, i.e., in situ in the shaped body. This results in attrition resistant bodies, without the need to add a binder material.

    摘要： The present invention pertains to cheaper process for the preparation of quasi-crystalline boehmite containing additive in a homogeneously dispersed state. In this cheaper process an inexpensive quasi-crystalline boehmite precursor is and additive are combined and aged to form a quasi-crystalline boehmite containing additive in a homogeneously dispersed state. Suitable inexpensive quasi-crystalline boehmite precursors are aluminum trihydrate and thermally treated forms thereof and inorganic aluminum salts. Suitable additives are compounds containing elements selected from the group of rare earth metals alkaline earth metals, transition metals, actinides, silicon, gallium, boron, and phosphorus.
