TRANSITION METAL-BASED NANOCATALYST, PREPARATION METHOD THEREOF AND USE IN FISCHER-TROPSCH SYNTHESIS REACTIONS

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to Fishcher-Tropsch synthesis catalysts. Described is a transition metal-based nanocatalyst for Fischer-Tropsch synthesis, which contains nanoparticles of a transition metal and polymer stabilisers, wherein the transition metal is selected from a group comprising ruthenium, cobalt, nickel, iron and rhodium, or any combination thereof, in which nanoparticles of the transition metal are dispersed in a liquid and the size of the nanoparticles of the transition metal is equal to 1-10 nm. Described is a method of preparing the described nanocatalyst, said method comprising the following steps: mixing and dispersing transition metal salts and polymer stabilisers in liquids, and reducing the transition metal salts with hydrogen in order to obtain a transition metal-based nanocatalyst, where temperature is equal to 100-200°C and concentration of the transition metal salts dissolved in the liquids is equal to 0.0014-0.014 mol/l. Described is a Fischer-Tropsch synthesis process which is carried out using the described nanocatalyst for converting carbon oxide and hydrogen to hydrocarbons.;EFFECT: obtaining an active nanocatalyst for the Fischer-Tropsch synthesis process.;17 cl, 1 tbl, 1 dwg, 10 ex
