FIELD: chemistry.
SUBSTANCE: invention relates to a method of regenerating one or more particle (particles) of the deactivated cobalt-containing Fischer-Tropsch catalyst in situ in the reactor tube, where the said catalyst particle(s) are deactivated by the application in the Fischer-Tropsch process, with the said regeneration method containing the following stages: (i) catalyst particle(s) is/are oxidised at a temperature from 20 to 400°C, preferably from 100 to 400°C, more preferably from 200 to 400°C; (ii) catalyst particle(s) is(are) processed with a solvent, containing ammonium carbonate and methylamine, ethylamine, propylamine and/or butylamine, for the time period longer than 5 minutes; (iii) catalyst particle(s) is/are dried and, optionally, heated; and (iv) catalyst particle(s) is/are reduced with hydrogen or a hydrogen-containing gas. The method of generating one or more particles of the cobalt-containing Fischer-Tropsch catalyst also contains s the following stages: (a) catalyst particle(s) is/are oxidised in the reactor pipe at a temperature from 20 to 400°C, preferably from 100 to 400°C, more preferably from 200 to 400°C; (b) catalyst particle(s) is/are discharged from the reactor pipe; (c) catalyst particle(s) is/are processed with a solvent, containing ammonium carbonate and methylamine, ethylamine, propylamine and/or butylamine, for the time period longer than 5 minutes; (iii) catalyst particle(s) is/are dried and, optionally, heated.
EFFECT: advantage of the method consists in the fact that during the processing stage only a small amount of cobalt is washed out, with the simultaneous reduction of the dissolved iron amount.
