A Method For Producing Carbon Black Using An Extender Fluid

摘要

Methods for the production of carbon black using an extender fluid(s) are provided as well as methods to control one or more particle properties of carbon black utilizing extender fluids and other techniques.

主权项

1. A method for producing carbon black comprising:
introducing a heated gas stream into a carbon black reactor; combining at least one extender fluid with at least one carbon black feedstock to form a fluid-feedstock mixture such that the at least one extender fluid increases the momentum of the at least one carbon black feedstock in a direction that is axial or substantially axial to at least one feedstock introduction point to the carbon black reactor;supplying said fluid-feedstock mixture to said at least one feedstock introduction point to the carbon black reactor,combining at least said fluid-feedstock mixture through the at least one introduction point to said carbon black reactor with the heated gas stream to form a reaction stream in which carbon black is formed in said carbon black reactor; and
recovering the carbon black in the reaction stream.
