The re-oxidation of low-pressure methanol synthesis catalyst was followed by means of DSC, with the aim of contributing to
a better understanding of the processes taking place during catalyst blanketing, stabilization and re-oxidation. The investigations
were carried out with previously hydrogen-reduced samples, and their successive re-oxidation was performed with different
oxygen contents in the oxygen/nitrogen gas mixtures. A procedure for catalyst stabilization and/or catalyst discharge is proposed.
