    摘要： Continuous charcoal production system in a vertical reactor with a concentric charging zone (1) and drying zone (2), a carbonization zone (3), a cooling zone (4) and a discharge zone (5), and a method for recovering energy from carbonization gases for the production of this charcoal, comprising the extraction of carbonization gas from the drying zone (2) and subdividing it into recirculating gas and heating gas, with the remaining gas exceeding the energy required to generate electricity; burning the heating gas in a hot gas generator (11); injecting the recirculating gas into a heat recovery unit (9); injecting the heating gas after combustion into the heat recovery unit (9), indirect heating of the recirculating gas; and reinjecting the heated recirculating gas into the carbonization zone (3) of the reactor (R).

    摘要： This document describes methods for pretreating coal to create either a dried coal or a char product that is stable in the outdoor environment and is more efficient as a feedstock for gasification or other processes than the original coal. Embodiments of the methods include pulverizing and pelletizing the coal, and pretreating the coal pellets to obtain a stable pellet of either dried coal or a stable pellet of chared coal (coal char). The pellets created by the described methods have undergone deoxygenation and carbonization improving their handling and storage properties and, in some cases, energy density. Pore structures within the pellets are stabilized physically and chemically so that the uptake of moisture into dry coal, that leads to internal heat generation, is greatly reduced. Chars are also, therefore, stable against transitions from a dry state to a wet state and less prone to self-ignition.

    摘要： Biogenic activated carbon compositions disclosed herein comprise at least 55 wt % carbon, some of which may be present as graphene, and have high surface areas, such as Iodine Numbers of greater than 2000. Some embodiments provide biogenic activated carbon that is responsive to a magnetic field. A continuous process for producing biogenic activated carbon comprises countercurrently contacting, by mechanical means, a feedstock with a vapor stream comprising an activation agent including water and/or carbon dioxide; removing vapor from the reaction zone; recycling at least some of the separated vapor stream, or a thermally treated form thereof, to an inlet of the reaction zone(s) and/or to the feedstock; and recovering solids from the reaction zone(s) as biogenic activated carbon. Methods of using the biogenic activated carbon are disclosed.
