ABSTRACT:
Feed oils are injected axially into a carbon black reactor in a manner which slows buildup of deposits in the reactor. This is accomplished utilizing a nozzle configuration for injecting the feed oil into the carbon black reactor so that deposit-forming contaminants are directed away from the walls of the reactor. In one aspect, the feed oil is separated into two streams, one stream is contaminant-rich and the other is substantially contaminant-free. The contaminant-rich stream is fed into the reactor surrounded by the substantially contaminant-free stream. In another embodiment, a feed nozzle for a carbon black reactor is formed by a first feed tube surrounded coaxially by a second feed tube. The first feed tube can be utilized to inject contaminant-rich feed oil into the reactor. The second feed tube can be utilized to inject contaminant-free oil into the reactor in a manner such that it surrounds the contaminant-rich stream. In an embodiment, one or more nozzles is provided at the outlet ends of the feed tubes for advantageous spray of feedstock.
