    Abstract: Carbide-derived carbons are provided that have high dynamic loading capacity for high vapor pressure gasses such as H2S, SO2, or NH3. The carbide-derived carbons can have a plurality of metal chloride or metallic nanoparticles entrapped therein. Carbide-derived carbons are provided by extracting a metal from a metal carbide by chlorination of the metal carbide to produce a porous carbon framework having residual metal chloride nanoparticles incorporated therein, and annealing the porous carbon framework with H2 to remove residual chloride by reducing the metal chloride nanoparticles to produce the metallic nanoparticles entrapped within the porous carbon framework. The metals can include Fe, Co, Mo, or a combination thereof. The carbide-derived carbons are provided with an ammonia dynamic loading capacity of 6.9 mmol g?1 to 10 mmol g?1 at a relative humidity of 0% RH to 75% RH.

  • Patent number: 10138378
    Abstract: A method and apparatus for making carbon black having increased surface area, reduced grit and/or reduced extract levels. A plasma gas is flowed into a plasma forming region to form a plasma. The plasma then flows through a throat region which is narrower than the plasma forming section, which is connected to a separate carbon black forming region. This causes the plasma to accelerate and become turbulent prior to the exit point in the throat region. The carbon black forming feedstock is injected into the turbulence created by the throat region at a point above, at or near the exit point, resulting in the formation of a carbon black in the separate carbon black forming region. The throat region and/or injector region can be cooled, e.g., water plasma gas cooled.

  • 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.

In the heating zones (11a, 11b, 11c) the product granulate is heated at a first temperature between 100° to 200° C., preferably 150° to 180° C., then at a second temperature between 200° to 350° C. and at a third temperature between 300° to 600° C. The temperature is maintained until such time that no further oil is emitted within the respective heating zone. As a final step, the product granulate is removed from the reactor (10) and the desirable solid materials are separated.

  • Patent number: 8236274
    Abstract: The invention relates to a carbon black having an aggregate size distribution which has a (d90-d10)/d50 ratio of less than or equal to 1.1. The carbon blacks are produced by admixing hot air if desired to a gas mixture comprising a carrier gas and a carbon black feedstock, passing the gas mixture into a burner pipe, burning the gas mixture at the burner pipe openings, and drawing the flames under suction, together with the ambient air drawn in freely under suction from the outside, through a cooled, narrowing gap, and carrying out cooling, the cooled, narrowing gap having a height (h) to width (b) ratio of 1-100, the width (b) being 0.5 to 10 mm, and the flow rate at the narrowest point of the gap being 10-200 m/s. The carbon blacks of the invention can be used as non-reinforcing filler, reinforcing filler, UV stabilizer, conductive black, pigment or reducing agent.

    Abstract: A method for the production of various morphologies of solid carbon product by reducing carbon oxides with a reducing agent in the presence of a catalyst. The carbon oxides are typically either carbon monoxide or carbon dioxide. The reducing agent is typically either a hydrocarbon gas or hydrogen. The desired morphology of the solid carbon product may be controlled by the specific catalysts, reaction conditions and optional additives used in the reduction reaction. The resulting solid carbon products have many commercial applications.

  • Publication number: 20120007027
    Abstract: Activated carbon blacks and the enhanced methods of preparing activated carbon blacks have been discovered. In order to form an activated carbon black, a conductive carbon black is coated with nanoparticles containing metal, and then catalytically activated in steam and an inert gas to form a catalytically activated mesoporous carbon black, where the mass of the catalytically activated carbon black is lower than the mass of the carbon black. The nanoparticles may serve as catalysts for activation rugosity of mesoporous carbon blacks. The catalytically activated carbon black material may be used in all manner of devices that contain carbon materials.
