FIELD: chemistry.
SUBSTANCE: invention claims methods for obtaining calcinated zirconium dioxide extrudates (variants) for application as carrier or catalyst containing zirconium and one or more other elements selected out of IB, IIB, IIIB, IVB, VB, VIB, VIIB and VIII groups of periodic element system, or lanthanides and actinides, involving the following stages: a. Obtaining formed paste by mixing and plastifying of fine dispersed zirconium dioxides and source of one or more other elements selected out of IB, IIB, IIIB, IVB, VB, VIB, VIIB and VIII groups of periodic element system, or lanthanides and actinides, and solvent, to obtain mix containing 50 to 85 wt % of solid substances, b. extrusion of formed paste to obtain zirconium dioxide extrudate containing zirconium and one or more other elements selected out of IB, IIB, IIIB, IVB, VB, VIB, VIIB and VIII groups of periodic element system, or lanthanides and actinides, and c. Drying and calcination of zirconium dioxide extrudate formed on b. stage, with fine dispersed zirconium dioxide containing under 15 wt % of zirconium dioxide other than monocline zirconium dioxide. Also invention claims calcinated zirconium dioxide extrudates obtained by the described method, and cobalt-saturated extrudate and its application in method for obtaining higher olefins in Fischer-Tropsch reaction.
EFFECT: enhanced crush durability of zirconium dioxide extrudates.
