  • Patent number: 10100200
    Abstract: A method of making carbon black. A method of making carbon black is described including combusting feedstock with plasma in an apparatus having a series of unit operations with individual capacities. The individual capacities of the unit operations are substantially balanced by replacing at least part of the feedstock with a feedstock having a molecular weight heavier than methane. This results, among other things, in increased utilization of the individual capacities of the unit operations and increased overall throughput.

  • Patent number: 10023466
    Abstract: A composition and a method for producing mesoporous carbon materials with a chiral or achiral organization. In the method, a polymerizable inorganic monomer is reacted in the presence of nanocrystalline cellulose to give a material of inorganic solid with cellulose nanocrystallites organized in a chiral nematic organization. The cellulose can be carbonized through thermal treatment under inert atmosphere (e.g., nitrogen or argon) and the silica may subsequently be removed using aqueous solutions of sodium hydroxide (NaOH) or hydrogen fluoride (HF) to give the stable mesoporous carbon materials that retain the chiral nematic structure of the cellulose. These materials may be obtained as free-standing films with very high surface area. Through control of the reaction conditions the pore-size distribution may be varied from predominantly microporous to predominantly mesoporous materials.

  • Patent number: 9975778
    Abstract: A method is described to make a chemically activated carbon by first immersing a suitable carbonized material into a neutral aqueous solution of inorganic salts that constitutes the chemical activating agent. The carbonized material is then removed and forms a chemically loaded activatable material that is separately heated at temperatures up to 1000° C. to form the chemically activated carbon. An additional CO2 or steam activation step is implemented to increase the surface area up to ˜3000 m2/gm. The chemical activating agents are nitrate salts in aqueous solutions, and may be reused since they are not directly heated as part of the activation process. The carbonized precursor materials include naturally occurring sources of carbon, synthetic polymeric materials and petroleum based sources.
