4.1.3. Radial-flow spherical reactor
Spherical reactor configuration has been investigated widely as
a suitable alternative to conventional tubular reactors [135–138].
This reactor setup has various advantageous respects to packed
bed reactor such as lower pressure drop, smaller catalytic pellets
with higher effectiveness factor, and lower required material thickness
[139]. This reactor configuration has been used in naphtha
reforming process in both axial-flow and radial-flow mode.
A schematic diagram of the radial-flow spherical packed-bed
reactor is shown in Fig. 9 [140,141]. This configuration consists
of two concentric sphere. The catalyst is charged in the space between
these spheres. The feed gas enters the reactor and flows
from the outside through the catalyst bed into the inner sphere.
The radial-flow in the spherical reactor offers a larger mean
cross-sectional area and reduced distance of travel for flow compared
to traditional vertical columns.
