A process for the preparation of an F-T catalyst in which the presence of alkaline earth metals is minimized in the support itself and in the processing conditions, in order to provide a catalyst with an alkaline earth metal content of less than 2000 ppm.

Fischer-Tropsch synthesis

A method of preparing a Fischer-Tropsch catalyst for handling, storage, transport and deployment, including the steps of impregnating a porous support material with a source of cobalt, calcining the impregnated support material, activating the catalyst, and passivating the activated catalyst.

Catalyst treatment

A method of producing an aluminum oxide supported catalyst for use in a Fischer-Tropsch synthesis reaction, which comprises: spray-drying a slurry of &#x3b3;-alumina and a source of a spinel forming metal to form a solid precursor material; calcining the precursor material to form a modified support material including a metal aluminate spinel; impregnating the modified alumina support material with a source of cobalt; calcining the impregnated support material, and activating the catalyst.

Fischer-tropsch catalysts

The invention relates to a novel method of preparing attrition resistance spinel supports for Fischer Tropsch catalysts. The process comprises: (a) combining aluminum oxide, metal compound capable of forming spinel phase, and soluble compound of a trivalent aluminum; (b) mixing the combination resulting in (a) in a manner sufficient to form a slurry comprising the aforementioned combination; and (c) processing the mixture of (b) under conditions sufficient to form metal aluminate spinel composition. Metal aluminate spinel, for example, is formed in the last step by calcining the mixture from (b) at a temperature in the range of 700 to 1300&#xb0; C., but the process is also capable, of producing attrition resistant supports (e.g., having a DI of 5 or less) at a relatively lower temperature in the range of 700 to 1050&#xb0; C. The invention also produces the attrition resistance with lower metal loadings than that reported for prior attrition resistant spinel supports.

Attrition resistant supports for fischer-tropsch catalyst and process for making same

A method of producing an alumina-supported cobalt catalyst for use in a Fischer-Tropsch synthesis reaction, which comprises: calcining an initial &#x3b3;-alumina support material at a temperature to produce a modified alumina support material; impregnating the modified alumina support material with a source of cobalt; calcining the impregnated support material, activating the catalyst with a reducing gas, steam treating the activated catalyst, and activating the steam treated catalyst with a reducing gas.

Fischer-Tropsch catalysts

A process for the regeneration of deactivated catalyst from a Fischer-Tropsch synthesis reactor, the catalyst being a supported cobalt catalyst. The process comprises the following steps: a withdrawal step, in which a portion of deactivated catalyst together with liquid hydrocarbon is withdrawn from the reactor; a concentration step, in which the concentration of the catalyst in the liquid hydrocarbon is increased; a calcination step, in which the deactivated catalyst composition is subjected to an oxidizing gas to oxidize carbonaceous material contained in the deactivated catalyst in to gaseous oxides of the components of the carbonaceous material; and a reactivation step, in which the deactivated catalyst composition is reactivated to produced a regenerated catalyst.

Fischer-Tropsch catalyst regeneration

A catalyst for use in a Fischer-Tropsch synthesis reaction which comprises cobalt supported on alumina, in which: the catalyst average particle size is in the range 20 to 100 &#x3bc;m; the specific surface area of the impregnated and calcined catalyst particles is greater than 80 m/g; the average pore size of the impregnated and calcined catalyst is at least 90 &#x212b; (9 nm); and the pore volume of the impregnated and calcined catalyst is greater than 0.35 cm/g.

Embodiments include a catalyst for use in a Fischer-Tropsch synthesis reaction which comprises cobalt supported on alumina. In some embodiments, the alumina support may have specific surface area of less than 50 m/g and/or may be least 10% &#x3b1;-alumina.
