Assignee:

Akzo Nobel N.V. - Arnhem

International Classification:

C01B 330

US Classification:

4234202

Abstract:

The present invention provides new compositions of matter, referred to as quasi-crystalline carboxylates (QCCs), their preparation and use. The materials comprise a quasi-crystalline hydrated magnesium-aluminium hydroxy carboxylate and are characterised by the presence of at least a strong reflection in the powder X-ray diffraction pattern at a basal spacing in the range of 5 to 15. The invention further relates to a process for preparing the QCCs, MgâAl solid solutions and anionic clays under acidic conditions. The QCC is prepared by aging an acidic mixture of a magnesium carboxylate and an aluminium source. Calcination of the QCC results in a MgâAl solid solution; rehydration of this solid solution gives an anionic clay.

Abstract:

Process for the preparation of an additive-containing anionic clay comprising the steps of (a) preparing a physical mixture of a divalent and a trivalent metal compound, (b) calcining the physical mixture at a temperature in the range 200-800 C. without performing a prior aging or shaping step, thereby forming a product containing at least 5 wt % of a rehydratable compound, and (c) rehydrating the calcined mixture in aqueous suspension containing an additive to form the additive-containing anionic clay. This process provides a simple and cost-effective way of preparing additive-containing anionic clays. The process does neither require aging or reaction steps before calcination, nor does it require precipitation of metal salts or the handling of inhomogeneous slurries.

US Classification:

502 68, 502 73, 502 80, 502 84

Abstract:

The invention relates to a composition comprising anionic clay and rare earth metal hydroxy carbonate. This composition can suitably be used in FCC for the reduction of NOx and/or SOx emissions, the reduction of the S and/or N-content in fuels, and as a metal trap. The composition can be prepared by precipitating a divalent metal salt, a trivalent metal salt, and a rare earth metal salt to form a precipitate, calcining the precipitate at 200-800 C. , and rehydrating the precipitate in the presence of a carbonate source to form a composition comprising anionic clay and a rare earth metal hydroxy carbonate.
