  • Patent number: 9434612
    Abstract: Systems and methods for thermally decomposing hydrocarbon feedstock may comprise a hydrocarbon feedstock, a non-oxidizing carrier gas, one or more heat exchangers, and a reaction chamber. The carrier gas may be used to transfer heat to the hydrocarbon feedstock. The heat exchanger(s) may be configured to heat the carrier gas. And the reaction chamber may be configured to receive hydrocarbon feedstock and heated carrier gas. Inside the reaction chamber, the hydrocarbon feedstock and the heated carrier gas may mix with one another causing the thermal decomposition reaction. The thermal decomposition reaction occurs in a substantially oxidant-free environment thereby eliminating or greatly reducing the production of carbon oxide byproducts. Hydrogen gas may be separated from a gaseous product stream that is thereafter collected from the reaction chamber. A portion of the gaseous product stream may be thermally coupled to the carrier gas and may thereafter be recycled through the system.

  • Patent number: 8968553
    Abstract: Undesirable components of traditional coking processes are selectively cracked or coked in the coking vessel by injecting an additive into the vapors in the coking vessel. The additive contains catalyst(s), seeding agent(s), excess reactant(s), quenching agent(s), carrier(s), or any combination thereof to modify reaction kinetics to preferentially crack (or coke) these undesirable components that typically have a high propensity to coke, and are often precursors to coke in the coking process. These undesirable components can also be very problematic in downstream catalytic cracking processes, significantly contributing to coke on catalyst and catalyst deactivation. Exemplary embodiments of the present invention also provide methods to (1) decrease coke production, (2) increase liquid transportation fuels, (3) control the coke crystalline structure, and (4) control the quantity and quality of volatile combustible materials (VCMs) in the resulting coke.

  • Patent number: 8557190
    Abstract: A carbon nanotube synthesis process apparatus comprises a reaction tube in which a reaction field is formed, and a discharge pipe (32) arranged downstream of the reaction tube and discharging carbon nanotubes to the outside. A plurality of nozzles (34) are provided on the sidewall of the discharge pipe (32) in directions which are deflected with respect to the center (O) of the discharge pipe (32). When gases are discharged from the plurality of nozzles (34), a swirl flowing from the inner side surface along the inner side surface is produced in the discharge pipe (32). Adhesion of carbon nanotubes to the inner side surface of the discharge pipe (32) is prevented by the swirl flow and thus the apparatus can be operated continuously.

  • Patent number: 6162411
    Abstract: A method for the production of fullerenic nanostructures is described in which unsaturated hydrocarbon fuel and oxygen are combusted in a burner chamber at a sub-atmospheric pressure, thereby establishing a flame. The condensibles of the flame are collected at a post-flame location. The condensibles contain fullerenic nanostructures, such as single and nested nanotubes, single and nested nanoparticles and giant fullerenes. The method of producing fullerenic soot from flames is also described.

  • Patent number: 6099965
    Abstract: This invention relates to rigid porous carbon structures and to methods of making same. The rigid porous structures have a high surface area which are substantially free of micropores. Methods for improving the rigidity of the carbon structures include causing the nanofibers to form bonds or become glued with other nanofibers at the fiber intersections. The bonding can be induced by chemical modification of the surface of the nanofibers to promote bonding, by adding "gluing" agents and/or by pyrolyzing the nanofibers to cause fusion or bonding at the interconnect points.

  • Patent number: 5997837
    Abstract: In a method for decomposition of hydrocarbons for the production of hydrogen and carbon black, the feed stock is passed through a plasma torch, which causes a pyrolytic decomposition of the feed stock. The feed stock is transported through the plasma torch (A) in a cooled lead-in tube (1) and undergoes a first heating in an area in the immediate vicinity of the plasma flame. The material thereby produced is passed on to one or more subsequent stages where the final and complete decomposition of the hydrocarbons to carbon black and hydrogen occurs. In this area further raw material may be added which causes quenching and reacts with the already produced carbon black. An increase is thereby caused in particle size, density and amount produced without further energy supply, whereafter the products produced are expelled and separated and hot gas may be transported in a return pipe to the torch, in order to further increase the energy yield.
