Abstract: PURPOSE: To reactivate a spent montmorillonite catalyst optionally repeatedly by thermal treatment of the spent montmorillonite catalyst at a specified temp. for a specified period. CONSTITUTION: In a process for reactivating a spent montmorillonite catalyst by thermal treatment, the spent montmorillonite catalyst is heated at a temp. of 650-850 deg.C for 0.2-3 hours. By using the process, the deactivated montmorillonite catalyst can be reactivated optionally repeatedly, and any treatment to make harmless or deposit allowable to environmental conditions otherwise required can be omitted. Not only the catalyst is regenerated to the initial activity and selectivity of the catalyst, but also they can exceed up to 1.3 times of initial ones as to the activity and selectivity.
