Abstract

Abstract: An accurate one-dimensional, heterogeneous model taking account of axial dispersion and
heat transferto the reactor wall, and heat conduction through the reactor wall for methanol
synthesis in a bench scale reactorunder periodic reversal of flow direction is presented.
Adjustable parameters in this model are the effectivenessfactors for each of the three
reactions occurring in the synthesis and a factor for the bed to wall heat
transfercoefficient correlation. Experimental data were used to evaluate these parameters
and reasonable values of theseparameters were obtained. The model was found to closely
predict the reactor performance under a wide range ofoperating conditions, such as carbon
oxide concentrations, volumetric flow rate, and cyclic period.

Key words: methanol synthesis, reverse flow reactor
