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： A method for making a catalyst is provided that features loading a catalytic metal to a support using at least two different precursor compounds of that said metal; and loading the promoter to the support in an amount effective so as to achieve similar promotion as for a comparable catalyst comprising a greater amount of the promoter using only one precursor compound, where the catalytic metal is selected from among Group 8 metals, 9 metal, Group 10 metals, and combinations thereof. The promoter is preferably boron, silver, a noble metal, or combination thereof. Also provided are catalysts made by the method and Fischer-Tropsch processes that include contacting synthesis gas with a catalyst made by the method.

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： The present methods feature an overall decrease in transportation costs and catalyst preparation/protection measures. A catalyst comprising a catalytic metal in an oxide form is safely transported in an oxidizing environment to a synthesis site, without any special precautions being taken before and during transport. The catalyst is then reduced with a reducing gas at the synthesis plant. The reduced catalyst is mixed with a stripped hydrocarbon liquid to form a catalyst slurry, wherein the stripped hydrocarbon liquid is substantially free of dissolved oxygen after being contacted with a stripping gas. The mixing can take place in a pre-operational hydrocarbon synthesis reactor, or at least a portion of the slurry can be transferred to at least one synthesis reactor either during operation or at the reactor start-up. A lessening of costs is realized as a coating step to minimize oxidative degradation of the catalyst is not required.
