METHOD AND APPARATUS FOR PROCESSING CARBON-CONTAINING MATERIAL Russian patent published in 2019 - IPC C10B49/04 

FIELD: chemistry.

SUBSTANCE: invention relates to processing of solid carbon-containing materials and can be used in production of not only activated carbon, but also for production of synthesis gas and synthesis fuel in various industries. Method for processing carbon-containing material includes heating of prepared carbon-containing material to temperature of carbonization in atmosphere, which is formed and moves in countercurrent mode with supplied raw material and formed by pyrolysis gas, activation with the help of an activating agent, unloading of hot carbon and its cooling, at which simultaneous supply of heat to two streams of combustion products is carried out to processed raw materials moving along a screw channel with gradually decreasing axial component of speed, and the obtained pyrolysis gas after carbonisation of the feedstock and activation of carbon is selected to obtain combustion products and an activating agent, carbonisation and activation processes are separately carried out in a carbonator and an activator, supply of heat of combustion products in carboniser is performed from two or more strongly swirled high-temperature flows of combustion chambers moving in counterflow of axial speed of processed raw material, wherein activation agent formation is carried out in three waste-heat boilers by supply of combustion products from carboniser annular channel to heat recovery boiler for water heating, and combustion products from carboniser cylindrical channel are supplied to waste heat boiler to produce steam from hot water supplied from heat recovery boiler for water heating, formed steam in a waste-heat steam boiler is supplied to a waste heat boiler for water vapour overheating. Invention comprises plant for implementation of method for carbon-containing material processing.

EFFECT: technical result of invention is to increase energy efficiency of technological process of processing carbon-containing material due to reduced consumption of energy resources of energy carriers.
