phenomena in a tubular catalytic bed reactor are numerically
investigated.  A two-dimensional pseudo-heterogeneous model,
accounting for transport in the solid and fluid phases, with
axial and radial dispersions, is used to describe the reactor.
The calculation results show the development of a hot spot in
the reactor. The effects of inlet process conditions are
investigated and their impact on the behavior of the reactor is
analyzed.
