摘要： A catalyst and method for producing hydrocarbons using a catalyst support having an improved hydrothermal stability, such as under Fischer-Tropsch synthesis conditions. The stabilized support is made by a method comprising treating a boehmite material in contact with at least one structural stabilizer. Contacting the boehmite with at least one structural stabilizer can include forming a mixture comprising the boehmite material and at the least one structural stabilizer. The mixture can be a sol or a slurry. The treating preferably includes drying or spray drying the mixture, and calcining in an oxidizing atmosphere to obtain the stabilized support. Preferred structural stabilizers can include an element, such as cobalt, magnesium, zirconium, boron, aluminum, barium, silicon, lanthanum, oxides thereof, or combinations thereof; or can include precipitated oxides, such as a co-precipitated silica-alumina.

摘要： 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.
摘要翻译：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。

摘要： 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.

摘要： A process is disclosed for the hydrogenation of carbon monoxide. The process involves contacting a feed stream comprising hydrogen and carbon monoxide with a catalyst system in a reaction zone maintained at conversion-promoting conditions effective to produce an effluent stream, preferably comprising hydrocarbons. In accordance with this invention the catalyst system used in the process includes at least one catalytic material for Fischer-Tropsch reactions (e.g., iron, cobalt, nickel and/or ruthenium), preferably comprising cobalt, and a support comprising aluminum borate. The catalyst system can be prepared by impregnating alumina with a boron-containing composition to form an aluminum borate support and applying a Fischer-Tropsch catalytically active material to the aluminum borate to form a supported catalyst system.
