Appeal 2007-1562
Application 10/865,666
of the carbon black (Br. 8). Representative independent claim 11, as
presented in the Brief, appears below:
11. A modular apparatus for producing carbon black
comprising:
a combustion zone having an upstream and a downstream
end and at least one port to allow the introduction of a fuel and an
oxidant;
a zone of converging diameter having an upstream and a
downstream end and converging from the upstream end towards
the downstream end, the upstream end being connected to the
downstream end of the combustion zone;
a transition zone having an upstream and a downstream end,
the upstream end being connected to the downstream end of the
zone of converging diameter, the transition including at least one
port to allow the introduction of a feedstock;
an apparatus for introducing a fluid stream into the reactor in
a direction axial to the flow of a process stream in the reactor, the
apparatus having an upstream and a downstream end, the upstream
end being connected to the downstream end of the transition zone;
a reaction zone having an upstream and a downstream end,
the upstream end being connected to the downstream end of the
transition zone or zones;
a quench zone having an upstream and a downstream end,
the upstream end being connected to the downstream end of the
reaction zone, the quench zone including at least one port to allow
the introduction of a quenching fluid; and
apparatus for separating and collecting carbon black
connected to the downstream end of the quench zone or zones.
