  • Patent number: 6485693
    Abstract: A process for producing carbon black comprising reacting a reaction stream formed by a prior carbon black forming process with an oxidant and a carbon black yielding feedstock to produce carbon black and cooling, separating and recovering the carbon black. The process advantageously reduces the amount of fuel needed to produce carbon black. Also disclosed is an apparatus for practicing the process.

  • Patent number: 6380517
    Abstract: A rotating vacuum kiln for heat treating solid particulate material under vacuum conditions uses a rotating refractory metal cylindrical vessel with a cool inlet zone, hot intermediate zone, and cool exit zone, with a first series of inner radiation shields provided at the hot intermediate zone adjacent to the cool inlet zone and a second series of inner radiation shields provided at the hot intermediate zone adjacent the cool exit zone to protect those two zones from the high temperatures in the hot intermediate zone. Heat for the hot intermediate zone of the cylindrical vessel is provided indirectly by electrical resistance heaters that surround the vessel and outer radiation shields are provided about the heaters to direct heat to the cylindrical vessel.

  • Patent number: 5879650
    Abstract: A method for increasing the aggregate size and structure of carbon blacks produced by a furnace carbon black reactor by lowering the temperature of, but not stopping pyrolysis in, the effluent (the mixture of combustion gases and feedstock in which pyrolysis is occurring), preferably up to about 800 degrees F., at a residence time between about 0.0 second and about 0.002 second downstream from the furthest downstream point of injection of feedstock.

  • Patent number: 5082502
    Abstract: Particles adhering to the internal surfaces of an object are removed by the movement of a shock wave past the surfaces. The shock wave is generated by the explosion of a gas in a chamber located inside the object. The invention has particular application for use in cleaning process equipment.

  • Patent number: 4563320
    Abstract: An extruder delivers an extrudate at a temperature in the low end of the extruding range between 250.degree. and 550.degree. F. between opposed rollers carrying mating dies. The dies are sprayed with mold release agent when away from the extrudate. The extrudate is cooled after leaving the region between a pair of rollers and may enter the region between other similar pairs of rollers. Cold plastic inserts may be inserted into molded items.

  • Patent number: 4354592
    Abstract: Self-cleaning apparatus for removing material from a rotating drum. Buckets are associated with a scraper which is maintained in a substantially fixed position relative to the local gravitational force vector. The scraper is maintained in said position by means of a counterweight. A scraping action is achieved as the drum and buckets rotate.

  • Patent number: RE28974
    Abstract: A process is provided for making high-quality carbon blacks at unusually good yields in a highly compact reaction space. The key steps of the process are the generation of a very hot combustion gas stream moving at very high speed in essentially plug flow by burning a hydrocarbon gas in oxygen in a compact combustion zone under conditions of very high heat release assuring the attainment of temperatures of over 3,000.degree. F., and the transverse injection into said highspeed combustion stream from the periphery thereof of a plurality of individual streams of liquid hydrocarbon make, each of which is injected under sufficient pressure to cause same to enter said high-speed combustion stream at a linear velocity of more than about 100 fett per second. Preferably, a highly oxygen-enriched oxidant is used to burn the hydrocarbon gas.
