  • 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.

    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.

    Abstract: A process for multistage thermal treatment of rubber waste, in particular scrap tires, is proposed. The process comprises several steps of transferring a product granulate of rubber waste into three different sequencing heating zones of a reactor (10). 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.

  • Publication number: 20130039840
    Abstract: The present invention discloses a reactor (100) for manufacturing carbon black, said reactor (100) comprising flow guide means (110) provided between a fuel burner (106) and an air inlet (108) for altering the flow path of combustion air entering at the air inlet (108) to result in a better mixing between the fuel and the combustion air, thereby, producing higher temperature hot combustion gases which are subsequently received in a reaction chamber (104) where they react with a carbonaceous feedstock to produce carbon black. The reactor (100) of the present invention increases the carbon black production by 5-20%. Further, the positioning of the flow guide means (110) stabilizes the flame from the fuel burner (106) to maintain it along the reactor axis, thus, increasing the life of the refractory lining (114).

  • Publication number: 20130030108
    Abstract: Carbon black includes primary particles having an average particle size of 15 to 40 nm, microprotrusions having an average length of 2 to 10 nm being formed on a surface of the primary particles. A method for producing carbon black includes introducing an oxygen-containing gas and fuel into a fuel combustion zone, mixing and combusting the oxygen-containing gas and the fuel to produce a high-temperature combusted gas stream, introducing a raw material hydrocarbon in a first stage of a raw material introduction zone and introducing the raw material hydrocarbon and an oxygen-containing gas in a second stage of the raw material introduction zone while introducing the high-temperature combusted gas stream into the raw material introduction zone to produce a carbon black-containing gas which is introduced into a reaction termination zone while spraying a coolant.

  • Publication number: 20120289753
    Abstract: The present invention relates to the recycling by depolymerisation through thermolysis. A method and installation for depolymerisation through efficient thermolysis for recycling is provided that allow the production of light hydrocarbons having high quality and being free of impurities and contaminants. This objective is achieved by methods and installations where either the secondary products of the process are re-fed to supply energy for the main recycling process or are refined to manufacture final usable and saleable products. Therefore, the use of the energy content of the starting materials is maximised by assuring their full utilisation, minimising the environmental harm while an energetically autonomous installation is provided. All the components of the waste or starting material may be recycled, by physico-chemical means, and no additional contaminant waste is produced.
