  • Patent number: 10233106
    Abstract: The invention relates to methods and to devices for a melting furnace, or for the conveying ones of the product to be melted, having an infinite life (furnace campaign). The same is achieved by means of the continuous/periodic, e.g. cyclic, exchange, in the optimum case, of all of the components surrounding the furnace interior/melting space, or surrounding the conveying lines, in that the components can be arranged/placed next to each other in a modular manner and that said components move in a certain direction while new individual parts are added at one of the free ends of the respective assembly and while worn/used individual parts are removed at the other free end of the respective assembly. For this purpose the individual components are held and/or moved by suitable receptacles, wherein the furnace interior/melting chamber remains stationary.

  • Patent number: 8951390
    Abstract: A reactor for the continuous production of charcoal, having a substantially vertical structure, comprising, in sequence, a top charging zone, a drying zone, a carbonization zone, a cooling zone, and a discharge zone, wherein the charging zone has a smaller cross section than the drying zone and has an extension into the drying zone , forming an annular space around the extension, which space comprises, in the wall of the drying zone, an outlet to a gas extraction line for the recirculation of these gases into the reactor. The reactor reduces sawdust drag by the gases extracted from the preheating zone, without substantially altering the shape and the size of the reactor, which is achieved due to the fact that the charging zone is arranged eccentrically relatively to the drying zone, and that the outlet to the gas extraction line of the drying zone is located substantially on the larger area section of the annular space.

  • Publication number: 20080286192
    Abstract: A pyrolysis process is provided. The process includes the steps of: depositing a quantity of waste into a porous container, the porous container adapted to allow a convective stream of substantially anaerobic gas to flow therethrough; inserting the porous container into a pyrolysis thermal processor; sealing the thermal processor; circulating the convective stream of gas through the pyrolysis thermal processor; heating the waste according to a first time-temperature profile to pyrolyze the waste and form a carbonaceous char; and cooling the carbonaceous char by circulating the convective stream of gas through a cooler. An oil product and a gaseous hydrocarbon product are produced during the pyrolysis. The carbonaceous char is further processed to form a carbon black product and a recyclable metal product.

  • Publication number: 20080219915
    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.

  • Patent number: 7368087
    Abstract: A gas re-use system for carbon fiber manufacturing processes based on hydrocarbon thermal decomposition. The system permits re-use of the output gas from the carbon fiber manufacturing process, a process based on the use of an industrial gas as the main raw material. The system can comprise a feedback pipeline provided with force and filtering means to raise the pressure from the reaction furnace output manifold to its input. There are also return and bleed lines operated separately to assure suitable pressure ranges at the same time both in the reaction furnace input area and extraction area.

  • Patent number: 7279137
    Abstract: The invention provides improved burners, combustion apparatus, and methods for carbon nanomaterial production. The burners of the invention provide sooting flames of fuel and oxidizing gases. The condensable products of combustion produced by the burners of this invention produce carbon nanomaterials including without limitation, soot, fullerenic soot, and fullerenes. The burners of the invention do not require premixing of the fuel and oxidizing gases and are suitable for use with low vapor pressure fuels such as those containing substantial amounts of polyaromatic hydrocarbons. The burners of the invention can operate with a hot (e.g., uncooled) burner surface and require little, if any, cooling or other forms of heat sinking. The burners of the invention comprise one or more refractory elements forming the outlet of the burner at which a flame can be established. The burners of the invention provide for improved flame stability, can be employed with a wider range of fuel/oxidizer (e.g.

  • Patent number: 6960234
    Abstract: A gasifier is disclosed combining a fixed bed gasification section where coarse fuel is gasified and an entrained flow gasification section where fine fuel is gasified. The fixed bed section includes upper and lower sections. Coarse fuel is devolatilized in the upper fixed bed section and subjected to elevated temperatures sufficient to crack and destroy tars and oils in the effluent gases. The entrained flow gasification section is disposed in a lower plenum adjacent the lower fixed bed section. A plurality of injection ports are configured to introduce oxygen, steam, or air into different sections of the gasifier to control temperature and operating conditions. Activated carbon may be formed in the upper fixed bed section and in the entrained flow section. The activated carbon may be used as a sorbent to remove pollutants from the effluent gases. The gasifier may be used with various coarse and fine fuel feedstocks.

  • Patent number: 6946101
    Abstract: A burner for producing carbon black, includes a combustion chamber which can be supplied with fuel gas and an oxidizing gas in such a way that a diffusion flame producing carbon black particles is generated in the combustion chamber. The burner is also provided with a carbon-black discharge line. Carbon black formed in the combustion chamber can be discharged via an opening in the combustion chamber which feeds into the carbon-black discharge line. The discharge line is also provided with an opening through which an extinguishing gas can be supplied to the carbon-line. The burner permits the stable and reproducible production of carbon black particles which present well defined chemical and physical characteristics.

  • Patent number: 6902708
    Abstract: Methods and apparatus are presented for producing carbon black on a substrate. One preferred method includes providing a head assembly including a nozzle, the nozzle including a first injector for injecting a gas such as acetylene, and a second injector for injecting a mixture of a fuel and an oxidant to produce a pilot flame. The head assembly is indexed over a substrate on which is to be deposited carbon black. The acetylene is injected through the first injector, then through a pilot flame emitted from one or more second injectors, and finally toward a substrate to be coated with carbon black, but only when a deposit of carbon black is desired. The method includes ceasing the flow of acetylene, indexing the head assembly away from the substrate on which was just deposited the carbon black after a carbon black deposition sequence, and ceasing fuel gas and oxidant gas flows through the second injector.
