    摘要: Disclosed is a method for extending the life of dehydrogenation catalysts used to prepare vinyl aromatic hydrocarbons. The catalysts, which typically include both iron oxide and potassium containing catalysis promoter, are exposed to additional potassium delivered using a potassium carboxylate. The potassium carboxylates are desirably free of halogens and other catalysts poisons or groups that could result in the undesirable properties in vinyl aromatic hydrocarbons produced therewith. The present invention is particularly useful with the production of styrene and methyl styrene.

    摘要: A method for producing small spherical particles that are especially useful as catalysts and catalyst supports employed in chemical processes is disclosed. According to some embodiments, the method includes impregnating a porous support with a metal or metal oxide and dissolving the support to release spherical particles. In certain embodiments the support that is employed in the method comprises a number of spherical voids which determine the size of the spherical particles, and preferably have micrometer range diameters. One embodiment of an attrition resistant Fischer-Tropsch catalyst comprises a plurality of micrometer size spherical metal and/or metal oxide particles that are prepared according to the above-described method.

    摘要: The present invention provides a process for producing spherical catalyst carrier of silica, silica-alumina composition, zirconia-alumina composition, titania-alumina composition, boria-alumina composition, or boria-silica-alumina composition which has almost the same pore characteristics as alumina hydrate gel, silica-alumina hydrate gel, zirconia-alumina hydrate gel, or titania-alumina hydrate gel (or alumina hydrate paste, boria-alumina hydrate paste, or boria-silica-alumina hydrate paste) as the major raw material, has uniform sphericity and smooth surface and homogeneity, and has a macropore volume that can be controlled. The process comprises adding a polysaccharide solution to any of alumina, silica-alumina, zirconia-alumina, or titania-alumina in the form of hydrate gel, or alumina, boria-alumina, or boria-silica-alumina in the form of hydrate paste, mixing them to form a slurry with a controlled concentration, dropping the slurry into a solution containing multivalent metal ions, thereby forming spherical hydrogel, and performing the additional steps of aging, washing, drying, and calcining.
