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.

摘要： A method and a device are provided for producing activated carbon in a gasification process. A first process stage includes thermally decomposing a carbonaceous starting material, in particular biomass, in a first reaction zone to produce pyrolysis coke and pyrolysis gas. A second process stage includes generating, from the pyrolysis gas in the second reaction zone, a product gas which can be used for activating the pyrolysis coke. A third process stage includes activating at least a portion of the pyrolysis coke to form activated carbon with the aid of the product gas in the third reaction zone.

摘要： There is provided a process and system for producing carbon fiber products. The process can involve deasphalting a heavy hydrocarbon feedstock, which can contain native asphaltenes, to produce a solid asphaltene particulate material, which can be further treated to produce the carbon fiber products. In some implementations, the solid asphaltene particulate material can be extruded in the presence of a polymer. In some implementations, the solid asphaltene particulate material can be chemically treated with a chemical agent including a Lewis acid, an oxidizing agent and/or a reducing agent before extrusion. In some implementations, the process can further produce activated carbon fibers.

摘要： A bio-oil light fraction-based bread-shaped porous activated carbon, a method for preparing the same and use thereof are provided. A light fraction prepared by fast pyrolysis of a biomass coupled with molecular distillation is selected as a precursor; an activator is directly mixed with the light fraction and stirred to obtain a homogeneous liquid; then, the homogeneous liquid is subjected to one-step carbonization and activation at a two-stage temperature in an inert atmosphere; after the activation, the obtained solid was washed and filtered, the activator reaction products and impurities are removed, and then dried to obtain the activated carbon used as an electrode carbon material of a supercapacitor. The method fully utilizes the rich micromolecule compounds such as water, acids, ketones, aldehydes, monophenols and the like in the obtained light fraction, and the micromolecule compounds and water can interact with the activator.

摘要： A method for preparing high specific surface area activated carbon through rapid activation, comprises the following steps: 1) selecting biomass raw material with a particle size of 0.3-0.9 mm; immersing the biomass raw material in a chemical reagent for 3-6 hours; and drying the biomass raw material in a constant-temperature drying oven of 100° C.-150° C. after immersing is ended; 2) stirring or crushing the dried material to form granular material after drying is completed; and 3) adopting a fluidized bed or a spouted bed as an activation reactor; increasing the temperature of the activation reactor to 700-800° C.; introducing fluidized gas; placing quartz sand; placing the granular material obtained in step 2); activating for 1-10 min; immediately discharging the material after activation is ended; and washing the material with water until the material is neutral to obtain activated carbon with a specific surface area of 1267-1359 m2/g.

摘要： The disclosure provides a system and method for production of activated carbon from a coal-originating particulate feed material. Feed material and activating gas are introduced into a reaction chamber, the activating gas being introduced at a velocity above the average terminal velocity of particles within the feed material. Feed material is then entrained in the activating gas such that a recirculating flow path for the feed material is established within the reaction chamber. Activated material may then be recovered from the chamber.
