Abstract
A process is provided for regenerating aged copper-containing coprecipitated methanol synthesis catalyst. The process includes treating the aged catalyst in an oxidizing atmosphere according to a specified time-temperature ramp, then in a reducing atmosphere. The oxidation-reduction cycle may be repeated as needed. An advantage of the invention is that the catalyst may be regenerated in situ in the same vessel in which the catalyst is utilized to make alcohol.
