Heat and mass transport 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.
