Abstract: A method for producing an activated carbon material comprises the steps of producing a hot flue gas stream from a combustion process in a first reactor; routing a first part of said flue gas stream to a second reactor that is substantially vertical; routing a second part of said flue gas stream to eventual venting; injecting and suspending a carbonaceous starting material into said second reactor to devolatilize and activate the carbonaceous starting material to produce an activated carbon material; separating the activated carbon material in a separating device; and routing the gas stream from said separating step to the first reactor for incineration of the volatile contents released from said injecting and suspending step. The activated carbon material is suited for the removal of vapor phase air toxics, such as mercury, from the flue gas of a coal fired power plant. An apparatus for producing the activated carbon material for the same purpose is also described.

Abstract: The present disclosure provides biorefining systems for co-producing activated carbon along with primary products. A host plant converts a feedstock comprising biomass into primary products and carbon-containing co-products; a modular reactor system pyrolyzes and activates the co-products, to generate activated carbon and pyrolysis off-gas; and an oxidation unit oxidizes the pyrolysis off-gas, generating CO2, H2O, and energy. The energy is recycled and utilized in the host plant, and the CO2 and H2O may be recycled to the reactor system as an activation agent. The host plant may be a saw mill, a pulp and paper plant, a corn wet or dry mill, a sugar production facility, or a food or beverage plant, for example. In some embodiments, the activated carbon is utilized at the host plant to purify one or more primary products, to purify water, to treat a liquid waste stream, and/or to treat a vapor waste stream.

Abstract: The present invention provides a system and a process for preparing activated carbon from fly ash. The system of the present invention comprises a flotation system and a carbonization system. The present invention has the following advantages. Firstly, since a fuel gas-flue gas loop structure is arranged, the combustible fuel gas produced in carbonization process enters the combustion means for combustion via this loop structure, and also via this loop structure, the high temperature flue gas generated by the combustion enters the carbonization furnace to heat up and carbonize the charcoal powder raw material within the carbonization furnace. Such a solution not only saves energy, but also prevents a substantial amount of combustible gas from being emitted to the atmosphere, thereby reducing environmental pollution. Secondly, since two cylinders are arranged in the carbonization furnace, the charcoal powder raw material in the inner cylinder enters the outer cylinder and then exits from the outer cylinder. In this way, with the length of the device unchanged, the route of the charcoal powder raw material is lengthened and its heating time is prolonged, so that the raw material is sufficiently heated and carbonized.

Abstract: SPENT ACTIVATED COAL IS REACTIVATED BY CONFINING A BODY OF IT IN A FLUIDIZED-BED REACTOR AND SUBJECTING IT TO FLUIDIZATION UNDER CONTINUOUS ADMISSION OF FLUE GASES OF A PREDETERMINED TEMPERATURE AND CONTAINING WATER VAPOR OR CARBON DIOXIDE. TREATED COAL IS CONTINUOUSLY REMOVED FROM THE FLUIDIZED BED AND THE TEMPERATURE OF THE LATTER IN THE REGION FROM WHICH THE TREATED COAL IS REMOVED IS MAINTAINED AT A CONSTANT TEMPERATURE LEVEL BELOW THE TEMPERATURE OF THE FLUE GASES, THE REGULATION OF THE CONSTANT TEMPERATURE LEVEL BEING ACCOMPLISHED BY CONTROLLING THE ADMISSION OF ADDITIONAL SPENT COAL INTO THE REACTOR AS AN INVERSELY PROPORTIONAL OF FLUCTUATIONS OF THE TEMPERATURE LEVEL.
