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.
Claims40
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 heat is added to the process downstream of where the feedstock is injected.
A carbon black generating apparatus, comprising:
- a heated fluid generating section;
- a carbon black producing feedstock injection section in fluid flow communication with the heated fluid generating section;
- and
- a carbon black forming feedstock cracking section in fluid flow communication with the feedstock injection section, wherein the carbon black forming feedstock cracking section comprises a supplemental heating section downstream of the feedstock injection section and produces (i) reduced wall fouling, (ii) increased or decreased surface area carbon blacks, (iii) increased or decreased structure carbon blacks, and/or (iv) higher throughput compared to in absence of the supplemental heating section.
A process of producing carbon particles, comprising:
- providing a hot fluid in a reactor;
- injecting a feedstock into the hot fluid to crack the feedstock, wherein the feedstock generates the carbon particles upon cracking;
- and
- adding external heat to the process downstream of where the hot fluid is provided.
A process of producing carbon particles, comprising:
- generating a hot fluid in a reactor;
- mixing a feedstock into the hot fluid to crack the feedstock, wherein the feedstock generates the carbon particles upon cracking;
- and
- adding external heat to the process during or after the mixing, thereby increasing a process temperature during or after the mixing (i) without increasing an amount of the hot fluid that is generated and (ii) without increasing a temperature of the hot fluid that is generated.
