METHOD OF OBTAINING CARRIER FOR CATALYST WITH HIGHER STABILITY (VERSIONS), CATALYST FOR SYNTHESIS OF HYDROCARBONS AND METHOD OF HYDROCARBONS SYNTHESIS FROM SYNTHESIS-GAS Russian patent published in 2008 - IPC B01J21/04 B01J21/08 B01J21/10 B01J21/12 B01J32/00 B01J37/04 B01J23/89 B01J37/02 C07C27/00 

FIELD: chemistry.

SUBSTANCE: catalyst includes stabilised carrier and catalytic metal. Stabilised carrier is obtained by processing boehmite in presence of structural stabiliser. Mixture is obtained, which contains boehmite and one structural stabiliszer compound, obtained mixture is dried, dry mixture including boehmite and, at least, one structural stabiliser, and dry mixture is tempered with obtaining stabilised carrier. It is described method of obtaining carrier (version), in which boehmite is dispersed in solvent and as a result sol is obtained, obtained sol is dried and dry boehmite is obtained, after that on obtained boehmite structural stabiliser compound is applied and as result carrier precursor is obtained, which includes boehmite and structural stabiliser and after that obtained carrier precursor is processed with obtaining stabilised carrier. It is described catalyst for obtaining hydrocarbons from synthesis-gas, which includes catalytically active metal, selected from group: cobalt, ruthenium, iron, nickel and their combinations, by choice, promoter, and stabilised carrier, obtained by method, which includes obtaining mixture, including boehmite and one structural stabiliser compound, drying of mixture and tempering of dry mixture, average size of stabilised carrier pores being more than 4 nm, and surface area - more than 30 m²/g of carrier, and its use in method of obtaining hydrocarbons from synthesis-gas.

EFFECT: higher hydrothermal stability of catalyst.
