A Fischer-Tropsch catalyst preferably includes a catalytically active first metal containing cobalt, and a carrier material containing silica or a silica compound with a cobalt surface area greater than 13 m2/g catalyst. The catalyst active in the FT reaction has a minimum alpha value of 0.87 and a CO conversion of 24 wt % or more. In accordance with another preferred embodiment, a process for producing a Fischer-Tropsch catalyst includes saturating silica or silica compounds with a solution of cobalt amine carbonate, removing the excess solution by filtration, heating the resulting product in order to allow cobalt hydroxycarbonate to precipitate, and drying and calcining the resulting product. Optionally the calcined product is reduced.

摘要： A method for making a silica supported catalyst involves impregnating a silica component with a catalytic metal using an aqueous, alkaline bath before drying. More specifically, the method involves forming and washing a silica component, such as a silica gel or a co-gel, for example a silica-zirconia co-gel. Then, the washed silica component is contacted with the alkaline bath to effect the impregnation with the catalytic metal, such as cesium, to form an activated silica component. Subsequently, the activated silica component is dried to form the catalyst. The resulting catalysts demonstrate good mechanical strength.

摘要： The present invention has an object to obtain a ceramic body that can support a required amount of catalyst component, without lowering the characteristics such as strength, being manufactured without forming a coating layer and providing a high performance ceramic catalyst body that is excellent in practical utility and durability. Such a ceramic body that is made by substituting at least one kind among the constituent elements of cordierite that constitutes the substrate ceramic, for example Al, with W that is the element having an empty orbit in d or f orbit, has high bonding strength and is less susceptible to deterioration since the catalyst component Pt is supported by means of chemical bonding.

摘要： A process and catalyst for the direct oxidation of an olefin having three or more carbon atoms, such as propylene, by oxygen to the corresponding olefin oxide, such as propylene oxide. The process involves contacting the olefin with oxygen under reaction conditions in the presence of hydrogen and in the presence of a catalyst. The catalyst comprises gold on a titanosilicate, preferably a microporous or mesoporous titanosilicate, such as, TS-1, TS-2, Ti-beta, Ti-ZSM-48, or Ti-MCM-41. Selectivity to the olefin oxide is high at good conversions of the olefin. The catalyst is readily regenerated, and the time between catalyst regenerations is long.
