FIELD: petrochemical process catalysts.
SUBSTANCE: cobalt-based catalyst precursor is prepared by impregnation of porous catalyst carrier particles with cobalt salt followed by partial drying and subsequent calcination of impregnated carrier, after which calcined product is partially reduced, impregnated with cobalt salt, partially dried and finally calcined. Preparation of Fischer-Tropsch catalyst comprises similar preparation of precursor thereof and reduction of the latter.
EFFECT: increased catalytic activity.
