| 摘要 |
The invention relates to petroleum, gas, and coal chemistry, especially to catalysts for C5-C100 hydrocarbons synthesis in particular from CO and H2 and a method for producing such catalyst. The proposed catalyst comprises an aluminum-oxide-based support obtainable from a gibbsite structure of aluminum hydroxide and cobalt, which content ranges from 15 to 50 wt %. The method comprises preparation of an alumina based support by mixing cobalt compounds with aluminum hydroxide and calcination, wherein the aluminum hydroxide having a structure of gibbsite, the mixing provided in the dry form with a mole ratio of cobalt and aluminum in the range of from 1:1 to 1:30; impregnation of the support in two or more stages with a water solution of cobalt salt; and thermal treatment. Embodiments include providing the thermal treatment by drying and/or calcination, additional introduction of substances-promoters into the support through impregnation with salts solution of the promoters.
