    摘要： 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.

    摘要： The present invention pertains to an improved process for the preparation of quasi-crystalline boehmite. In this improved process a quasi-crystalline boehmite precursor is aged at a pH below 7, prefereably under hydrothermal conditions. It was found that when conducting the preparation processes for quasi-crystalline aluminas described in the prior art at a pH below 7 and under hydrothermal conditions instead of the high pH and thermal aging used in the prior art, QCBs with higher crystallinity are obtained. In the process according to the invention additives may be added to the quasi-crystalline boehmite precursor. This results in a high quality QCB with additives in a homogeneously dispersed state. 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.
