Abstract: An amorphous support, methods for making the same and methods of using, particularly in hydrocracking. A method of making may comprise mixing a first amorphous material and a second amorphous material of different acidities to form a mixture, and treating by either separately treating the first and second amorphous materials before mixing or treating the mixture, so as to form an amorphous catalyst support. Treating preferably includes calcining. The acidity of the amorphous support may be modified by the different acidities of the precursor amorphous materials, their proportions in the mixture, and/or the order of the mixing and treating steps. A method of use may comprise reacting a hydrocarbon fraction with hydrogen over a hydrocracking catalyst comprising the amorphous catalyst support to form a hydrocracked product. Further embodiments include the first and second amorphous materials comprising silica-alumina, and/or differing in Brönsted acidity, Lewis acidity, or acidity index.

Abstract: This invention relates to catalysts comprising a catalytic metal deposited on a composite support with well-dispersed chemical “anchor” species acting as nucleation centers for catalytic metal crystallites growth. The catalysts have the advantage that the average catalytic metal crystallite size can be controlled by the molar ratio of catalytic metal to chemical “anchor,” and is not limited by the porous structure of the support. A preferred embodiment comprises a cobalt-based catalyst on a silica-alumina support made by a co-gel method, wherein its average pore size can be controlled by the pH. The alumina species in the support most likely serve as chemical “anchors” to control the dispersion of cobalt species, such that the average cobalt crystallite size can be greater than the average pore size.

Abstract translation: 本发明涉及包含沉积在复合载体上的催化金属的催化剂，其具有充分分散的作为催化金属微晶生长的成核中心的化学“锚”物质。 催化剂的优点在于，催化金属的平均催化金属粒度可以通过催化金属与化学“锚”的摩尔比来控制，并不受支持体的多孔结构的限制。 优选的实施方案包括在通过共凝胶法制备的二氧化硅 - 氧化铝载体上的钴基催化剂，其中其平均孔径可以由pH控制。 载体中的氧化铝物质最有可能用作化学“锚”以控制钴物质的分散体，使得平均钴微晶尺寸可以大于平均孔径。

Abstract: An effective catalyst includes an amorphous silica-alumina support having a bimodal pore size-distribution. The support may be prepared by a method that includes the physical mixing of two silica-alumina gels prepared so as to have two different average pore sizes. The catalyst has the advantage that both metal dispersion on the support and product diffusion in the pores are optimized. Further, the catalyst has improved performance in the production of hydrocarbons from synthesis gas.

Abstract: A process has been developed for preparing a Fischer-Tropsch catalyst precursor and a Fischer-Tropsch catalyst made from the precursor. The process includes contacting a gamma alumina catalyst support material with a first solution containing a compound containing an element selected from the group consisting of yttrium (Y), niobium (Nb), molybdenum (Mo), tin (Sn), antimony (Sb) and mixtures thereof to obtain a modified catalyst support material. The modified catalyst support material is calcined at a temperature of at least 700° C. The calcined modified catalyst support has a pore volume of at least 0.4 cc/g. The modified catalyst support is less soluble in acid solutions than an equivalent unmodified catalyst support. The modified catalyst support is contacted with a second solution which includes a precursor compound of an active cobalt catalyst component to obtain a catalyst precursor. The catalyst precursor is reduced to activate the catalyst precursor to obtain the Fischer-Tropsch catalyst. The catalyst has enhanced hydrothermal stability as measured by losing no more than 25% of its pore volume when exposed to water vapor.
