FIELD: technological processes. ^ SUBSTANCE: present invention relates to a catalyst for hydrocarbon production from synthesis gas, to method of its production, method of such catalyst regeneration and method of hydrocarbon production with application of such catalyst. A catalyst is described to produce hydrocarbon from synthesis gas, in which metal cobalt or metal cobalt and cobalt oxides; and zirconium oxides are applied onto a catalyst substrate, which mainly consists of a silicon dioxide. This catalyst is characterised by the fact that content of admixtures in the catalyst makes less or is equal to 15 wt %. Versions of the method are described to produce such catalyst, where the catalyst is produced by simultaneous or separate application of cobalt and zirconium compounds onto a catalyst substrate by impregnation method, impregnation method by moisture capacity, by method of deposition or method of ion exchange and performance of restoration treatment or baking and restoration treatment. Versions are described to regenerate such catalyst, where the catalyst with reduced activity is treated with a regenerating gas, containing hydrogen, or regenerating gas is supplied into a reactor, or regenerating gas is supplied into any part of the outer circulation system, and the catalyst and the regenerating gas contact with each other. Versions of the method to produce hydrocarbon from synthesis gas with application of such catalyst are described, where the method is carried out with performance of reaction in a liquid phase using a reactor with a layer of suspended residue or a layer of suspended residue with an external circulation system. ^ EFFECT: production of catalyst having high activity, durable service life and high resistance to water without loss of strength and wear resistance. ^ 31 cl, 3 tbl, 2 dwg, 21 ex |
