FIELD: chemistry.
SUBSTANCE: described is a catalyst used in a synthetic gas conversion process, where the said catalyst contains: a) a substrate formed from a composite spinel structure with formula MxM'(1-x)Al2O4/Al2O3●SiO2, where x varies from 0 to 1 exclusively, or with a simple spinel structure with formula MAl2O4/Al2O3●SiO2 in which M and M' are different metals selected from a group consisting of: magnesium, copper, cobalt, nickel, tin, zinc, lithium, calcium, caesium and sodium, and Al2O3●SiO2 is the chemical formula of aluminium silicate, where the said substrate is burnt in at least a partially oxidative atmosphere at temperature ranging from 850°C to 900°C, b) an active phase deposited on the said substrate containing one or more group VIII metals selected from cobalt, nickel, ruthenium or iron. The said catalyst is used in a fixed bed or in a suspension in a three-phase reactor for synthesis of hydrocarbons from a mixture containing carbon monoxide and hydrogen.
EFFECT: increased activity of the catalyst, its hydrothermal stability and resistance to mechanical wearing.
