    摘要: Oxidic composition consisting essentially of oxidic forms of a first metal, a second metal, and optionally a third metal, the first metal being either Fe or Zn and being present in the composition in an amount of from about 5 to about 80 wt %, the second metal being Al and being present in the composition in an amount of from about 5 to about 80 wt %, the third metal being selected from the group consisting of Mo, W, Ce, and V, and being present in an amount of from 0 to about 17 wt %—all weight percentages calculated as oxides and based on the weight of the oxidic composition, the oxidic composition being obtainable by (a) preparing a physical mixture comprising solid compounds of the first, the second, and the optional third metal, (b) optionally aging the physical mixture, without anionic clay being formed, and (c) calcining the mixture. This composition is suitable for use in FCC processes for the reduction of SOx emissions from the regenerator and for the production of sulphur-lean fuels and has only a minimised influence on the zeolite's hydrothermal stability.

    摘要: The invention relates to a catalyst composition comprising anionic clay, lanthanum (hydr)oxide carbonate, and cerium oxide. 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 forming a precipitate from a solution comprising a divalent metal salt, a trivalent metal salt, a lanthanum salt, and a cerium salt, calcining the precipitate at 200-800° C., and rehydrating the calcined precipitate in the presence of a carbonate source to form a composition comprising anionic clay, lanthanum (hydr)oxide carbonate, and cerium oxide.

    摘要: The present invention relates to a process for the preparation of doped pentasil-type zeolite, which process comprises the steps of: a) preparing an aqueous precursor mixture from a silicon source, an aluminium source, and doped non-zeolitic seeds; and b) thermally treating the precursor mixture to form a doped pentasil-type zeolite. The term “non-zeolitic seeds” includes seeds made from materials selected from the group consisting of (i) X-ray amorphous materials, (ii) milled crystalline materials, such as milled zeolites, that have a relative crystallinity of not more than 75%, and (iii) crystalline materials other than zeolites, such as clays (e,g, bentonite and kaolin) and (low) crystalline aluminas.
