  • Process for feeding particulate material to a fluidized bed reactor
    Patent number: 6077920
    Abstract: The present invention provides a process and apparatus for feeding powders such as fine, cohesive, or powdery particulate materials from a low pressure system to a high pressure system. In a preferred embodiment a process and apparatus of pressurizing and feeding carbon black fluff to a polymerization reactor is provided particularly a gas phase fluidized polymerization reactor to provide for a close-coupling of a carbon black reactor to a polymerization reactor.
