• A gas handling and mix-
ing sub-system used to
blend and regulate the
flow of reactant gas to
the bottom of the reactor.
• The reactor (Diagram
1) is roughly one meter
long with a 2.5 cm ID.
The lower portion of the
reactor incorporates an
easily replaced porous
metal gas diffusion plate
and the top of the reac-
tor widens abruptly to
form a disengaging zone
for the fluidized bed.
Separate heaters are
provided for both the
main reactor and dis-
engaging zone. A mul-
tipoint thermocouple is
provided for monitoring
the internal reactor tem-
perature distribution.
• A heated cyclone separa-
tor (Diagram 2) or filter
is provided immediately
downstream of the reac-
tor to capture the fines
resulting from particle
attrition.

• The reaction products are then cooled by a condenser
and collected in a 600 mL product receiver.
• The system pressure is maintained by a dome loaded
back pressure regulator.
• All system functions and parameters are monitored
and maintained by a Parr 4871 Process Controller.
