METHOD OF PRODUCING SUPPORTED COBALT-BASED FISCHER-TROPSCH SYNTHESIS CATALYST Russian patent published in 2012 - IPC C10G2/00 B01J23/75 B01J37/18 C07C1/04 

FIELD: chemistry.

SUBSTANCE: method involves: a first step for activation treatment of particles of a supported cobalt-based Fischer-Tropsch synthesis catalyst precursor, having a catalyst support saturated with cobalt, a hydrogen-containing reducing gas or a nitrogen-containing gas at a first heating rate HR1 until temperature of the precursor reaches a value T₁, where 80°C≤T₁≤180°C, to form a partially treated catalyst precursor; a second step for activation treatment of the partially treated catalyst precursor with a hydrogen-containing reducing gas at a second heating rate HR2 with step x, where x is an integer greater than 1 and 0≤HR2<HR1, wherein the precursor is heated from temperature T1 to temperature TH, where TH>T1 and TH<200°C for a time t₁, where t₁ is equal to 0.1-20 hours, to form a partially reduced catalyst precursor; and then a third step for activation treatment of the partially reduced catalyst precursor with a hydrogen-containing reducing gas at a third heating rate HR3, where HR3>HR2, until temperature of the partially reduced catalyst precursor reaches a value T₂, where 300°C≤T2≤600°C and holding the partially reduced catalyst precursor at T₂ for a time t₂, where t₂ is such that 0<t₂≤20 hours, to form an activated supported cobalt-based Fischer-Tropsch synthesis catalyst.

EFFECT: obtaining a high-activity catalyst.
