ABSTRACT:
A catalyst applicable to the synthesis gas conversions especially E-T slurry processes, said catalyst comprising: a) a support containing at least a first aluminate element of mixed spinel structure of formula MxM′(1−x)Al2O4/Al2O3.SiO2, x ranging between and excluding 0 and 1, or of simple spinel structure of formula MAl2O4/Al2O3.SiO2, said support being calcined in an at least partly oxidizing atmosphere, at a temperature ranging between 850° C. and 900° C., and b) an active phase deposited on said support, which contains one or more group VIII metals, selected from among cobalt, nickel, ruthenium or iron. Said catalyst is used in a fixed bed or suspended in a three-phase reactor for hydrocarbon synthesis from a CO, H2mixture.
