FIELD: petroleum processing. ^ SUBSTANCE: hydrocarbon stock processing that can be used in production of activated carbon comprises preliminary thermal treatment thereof using gaseous heat carrier followed by processing at 200-900°C in reactor under reductive gas atmosphere in presence of saturated steam supply, cooling, and discharging activated carbon. Reductive gas is generated by combusting hydrocarbon fuel with air consumption ratio below 1.0 and then mixed with thermochemical processing gases in proportion 1:(0.1-10). In order to control temperature conditions, reductive gas is fed to at least three reaction zones and, prior to be fed to each individual reaction zone, reductive gas is preliminarily mixed in proportion ensuring specified temperature conditions in different zones, whereas process is carried out according to known temperature regimes in production of products with specified parameters. ^ EFFECT: expanded process possibilities due to enabled temperature conditions control, increased accuracy in achieving specified parameters of product, and reduced power consumption. ^ 2 cl, 1 dwg, 2 ex |
