METHOD OF PRODUCING ACTIVATED COAL AND SYSTEM OF EQUIPMENT FOR PRODUCTION OF SAID ACTIVATED COAL Russian patent published in 2009 - IPC C01B31/08 

FIELD: chemistry.

SUBSTANCE: method involves pyrolysis and activation. Pyrolysis is carried out in a furnace, in the top part of which material is dried by flue gases. Coal is unloaded at the bottom of the furnace and cleaned from ash and impurities on a slide with a perforated bottom. Also there is a coil inside the furnace for obtaining vapour which is used for activation in the container. Before activation, the coal is burnt and carbonised in a chamber, which is made in form of a heat-insulated pipe. The system of equipment consists of a device for producing an activating agent, made in form of a coil which is placed in the pyrolysis furnace. In the pyrolysis furnace there is a device for spacing coal, which is made in form of a chain. At the bottom of the furnace there is a slide with a perforated bottom, through which cleaned coal enters the chamber for burning and carbonisation, made in form of a heat-insulating pipe with a trap. A branched perforated pipe passes through the container for activation and is connected to the coil inside the pyrolysis furnace. There is an opening on the cover of the container, which is linked with the chamber for burning and carbonisation, and an opening for outlet of gases.

EFFECT: design of a method of producing activated coal and system of equipment for production of activated coal, with high efficiency and low energy consumption.
