    摘要： Disclosed are apparatus and method for preparing carbon black, in which the carbon black may be continuously formed and activated. In one embodiment, carbon black powders formed in a combustion reactor are converted into a slurry which in turn is refluxed to the combustion reactor in a repeated manner, thereby to allow successive activation treatments. In this way, a sufficient residence time for the activation of the carbon black may be secured.

    摘要： Jute stick/stalk can be used to prepared and carboxylated to yield useful activated carbons, e.g., for removing Pb2+ from drinking water. Such activated carbons can act as an inexpensive adsorbents using agricultural waste or by-products. Carboxylation of jute stick activated carbon (JSAC) can improve its efficiency for Pb2+ removal, e.g., from aqueous solutions, even if its BET surface area is reduced. Carboxylated JSAC (JSAC-COO−) can have surface areas around 615.3±0.5, 1, 2.5, 5, 10, 15, 20, or 25 m2/g. JSAC-COO− can treat varied Pb2+ concentrations, 10, 25 mg/L, etc., pHs, e.g., 4.0, 7.0, etc., temperatures, e.g., 15° C., 27° C., etc., and contact periods, e.g., 1, 5, 10, 15, 30, 60 minutes, etc., achieving up to 99.8% Pb2+ removal within 15 minutes of contact JSAC-COO− adsorption capacity can be >25.0 mg Pb2+/g, as well as other metal ions, with potential for water and/or gas treatment.

    摘要： The invention provides a method for making multiporous carbon material from a bio-oil produced by a biomass thermochemical process. The bio-oil is blended with a resin and a Zinc Oxide (ZnO) template as a major component of a precursor. The pore sizes of the carbon material made by the invention comprise mesopores and micropores to form the multiporous carbon material. The main production steps include: (1) mixing the precursor with a crusher, (2) packing the precursor, (3) heating for carbonization: holding 350° C. for 1 hour then holding 900° C. for 2 hours, and (4) washing the ZnO with hydrochloric acid by adjusting the pH value to less than 1.

    摘要： A porous carbon material includes a hierarchical porous structure including a primary microporous structure and at least one of a secondary mesoporous structure and a secondary macroporous structure. The porous carbon material is formed by combining a halogenated-hydrocarbon, an aprotic hydrocarbon solvent, and a reductant to initiate a reaction that forms intermediate particles having a microporous framework; and subjecting the intermediate particles to a heat treatment at a heat treatment temperature ranging from about 300° C. to less than 1,500° C. for a heat treatment time period ranging from about 20 minutes to about 10 hours to thereby form the porous carbon material. The aprotic hydrocarbon solvent is selected from the group consisting of toluene, hexane, cyclohexane, and combinations thereof.
