Abstract
Secondary heat may be added to a particle production process. The particles may be, for example, carbon particles. Among other things, the secondary heat addition may result in change in surface area of the carbon particle(s), change in structure of the carbon particle(s), reduced wall fouling, reduced energy consumption and/or increased throughput. Apparatus for performing the process is also described.
Claims33
A process of producing carbon black, comprising:
- creating a hot fluid, followed by injecting a carbon black producing feedstock into the hot fluid to crack the feedstock to form the carbon black, wherein the feedstock is a hydrocarbon comprising methane, ethane, propane or mixtures thereof, and wherein heat is added to the process downstream of where the feedstock is injected.
A process of producing carbon black, comprising:
- creating a hot fluid, followed by injecting a carbon black producing feedstock into the hot fluid to crack the feedstock to form the carbon black, wherein the hot fluid is a plasma comprising greater than about 70% H2, and wherein heat is added to the process downstream of where the feedstock is injected.
