    摘要: 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.

    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 Ca or Ba 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 La, Ti, and Zr, 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 passivation of metals with only minimal influence on the zeolite's hydrothermal stability.

    摘要: A continuous process for the hydrothermal conversion of a solid starting iron compound selected from the group of iron oxides, iron hydroxides, iron oxyhydroxides, and mixtures thereof into a solid product iron compound with different physical, chemical, and/or structural properties. The process comprises the steps of a) dispersing the solid starting iron compound in a liquid thus forming a suspension, and b) feeding the suspension continuously though one or more agitated conversion vessel(s), in which vessel(s) the solid starting iron compound is converted into the solid product iron compound under hydrothermal conditions.

    摘要: A catalyst composition comprising about 5–55 wt % metal-doped anionic clay, about 10–50 wt % zeolite, about 5–40 wt % matrix alumina, about 0–10 wt % silica, about 0–10 wt % of other ingredients, and balance kaolin. In metal-doped anionic clays, the additive, i.e. the metal dopant, is distributed more homogeneously within the anionic clay than in impregnated anionic clays, without separate phases of additive being present. Hence, abrasion of this catalyst composition will result in microfines poorer in additive than the prior art composition. Furthermore, the catalyst composition according to the invention results in a higher reduction of sulfur in fuels such as gasoline and diesel than is the case in compositions comprising impregnated anionic clay.
