Methanol synthesis catalyst deactivation

Methanol Synthesis - Theory and Operation

The current knowledge of the deactivation phenomenon of the low-temperature gasphase methanol synthesis catalyst is reviewed. Under normal operating conditions, the catalyst Cu-Zn oxide has a rather long lifetime of a few years.
