Abstract
An olefin hydration catalyst is regenerated with a non-oxidizing light gas, such as hydrogen. Light olefins, especially propylene, are converted to a mixture of alcohol(s), such as isopropanol (IPA) and ether(s), such as diisopropylether (DIPE) by contacting a feed containing the olefin with water and/or alcohol with the olefin hydration catalyst. Regeneration conditions include temperatures of from about 150.degree. C. to about 550.degree. C., pressures below about 1000 psig (6900 kPa). Lower pressures of regeneration unexpectedly demonstrated more effective catalyst regeneration through greater coke removal.
