A method of reducing catalyst wear losses for hydrocarbon synthesis processes performed in highly stirred reaction systems; Abrasion resistant catalyst production method; A catalyst prepared by this method; A process for producing a wear resistant catalyst support; And a catalyst prepared by this method. The present invention and catalyst have several embodiments. In one embodiment, the catalyst preferably comprises a γ-alumina support comprising an amount of titanium effective to increase the wear resistance of the catalyst. In another embodiment, the catalyst preferably comprises a γ-alumina support treated with an acidic aqueous solution after calcination. In another embodiment, the catalyst preferably comprises cobalt on a γ-alumina support, the cobalt being entirely aqueous Co-impregnation is applied to the γ-alumina support by initial wetting. In another embodiment, the catalyst preferably comprises cobalt on the γ-alumina support with an amount of lantana enhancer effective to increase the wear resistance of the catalyst. In another embodiment, the catalyst comprises a γ-alumina support prepared on the 021 side from boehmite, preferably having a microcrystalline size in the range of about 30 to about 55 angstroms. The use of such catalysts in highly stirred reaction systems results in reduced catalyst wear losses. |
