Abstract:
1. A method of preparing an ion exchange resin catalyst comprising: (a) partially filling a vessel, from 50 volume percent to 95 volume percent of said vessel, with an ion exchange resin catalyst to form an ion exchange resin catalyst bed in the vessel; (b) introducing a liquid into the vessel; (c) recirculating the liquid through the catalyst bed in an upflow direction; (d) introducing a promoter into the recirculating liquid; and (e) maintaining the recirculating liquid at a velocity in a range of from 0.5 meters (m)/hour (hr) to 100 m/hr sufficient to achieve at least 5 percent catalyst bed expansion and mobilize the ion exchange resin catalyst to evenly and rapidly distribute the promoter throughout the catalyst bed.
