METHOD OF REGENERATING COBALT-CONTAINING CATALYST FOR OBTAINING SYNTHETIC HYDROCARBONS IN ACCORDANCE WITH FISCHER-TROPSCH METHOD Russian patent published in 2015 - IPC B01J38/02 B01J38/16 B01J38/30 B01J23/75 C07C1/04 

FIELD: chemistry.

SUBSTANCE: regeneration includes oxidation of deactivated catalyst by supply of air into reactor zone at rate 500-2000 h^-1, heating to temperature 200-270°C at heating rate 1-3°C/min and exposure at said temperature in air flow for 1-5 h. Further reduction is carried out by supply of hydrogen-containing gas at oxidation temperature with volume rate 1000-5000 h^-1, heating to temperature 300-600°C at rate 1-5°C/min and exposure at heating temperature in flow of hydrogen-containing gas for 1-5 h. Method includes carrying out additional stage of deactivated catalyst reduction with hydrogen-containing gas before redox regeneration. Hydrogen-containing gas of the similar composition with hydrogen content from 20 to 100 vol % is used in reduction.

EFFECT: increased efficiency of regeneration and increase of catalyst service duration in comparison with other methods known in technology.
