FIELD: chemistry.
SUBSTANCE: present invention pertains to obtaining catalysts, particularly catalysts for dehydrogenation of paraffin hydrocarbons into olefins. Description is given of a catalyst for dehydrogenation of C3-C5-paraffin hydrocarbons into olefins, containing, in wt %: chromium (III) oxide - 8.0-23.0; alkali metal oxide - 0.5-3.5; zirconium oxide or a mixture of oxides of zirconium, hafnium and titanium with mass ratio of 1:(0.01-0.3):(0.001-0.05)-0.05-5.0; carrier - rehydrated oxygen-containing aluminium compound with general formula: Al2O3-x(OH)2x·nH2O, where x=0.1-0.5, n=0.7-1.5, with an x-ray amorphous structure, containing 10-50% pseudo boehmite.
EFFECT: increased catalytic activity and stability due to reduced loss during attrition.
