PROCESS FOR THE PRODUCTION OF ACTIVATED CARBON

PROCESS FOR THE PRODUCTION OF ACTIVATED CARBON

Activated carbon is produced from a partially hydrolyzed vegetable waste material in a process including activation with at least one of the agents steam, carbon dioxide and flue gas, in which either one activating agent is dosed continuously or several activating agents are dosed alternately. A was...

description Activated carbon is produced from a partially hydrolyzed vegetable waste material in a process including activation with at least one of the agents steam, carbon dioxide and flue gas, in which either one activating agent is dosed continuously or several activating agents are dosed alternately. A waste material autocatalytically hydrolyzed by an organic acid is used as the partially hydrolyzed waste material, said waste material is heated indirectly or directly between 150 and 400 DEG C at a heating- up rate of 10 to 40 DEG C/min, between 400 and 600 DEG C at a heating-up rate of 15 to 30 DEG C/min, then heat-treated at a temperature of 500 to 600 DEG C for a period not exceeding 30 minutes and finally activating the product with a residence time not exceeding 30 minutes.
