Title:
REGENERATING METHOD FOR ACTIVATED ALUMINA USED IN REGENERATING WORKING FLUID OF HYDROGEN PEROXIDE
Document Type and Number:
WIPO Patent Application WO/2009/026792
Kind Code:
A1
Abstract:
A regenerating method for activated alumina used in regenerating working fluid
of hydrogen peroxide comprises the following steps: adding deactivated alumina
discharged from a regenerating bed for working fluid of hydrogen peroxide into
a reactor through the top of the reactor and settling by gravity, oxidizing atmosphere
entering into the reactor from the bottom of the reactor and running upwardly,
then discharging exit gas and regenerated alumina through the discharge port
on the top and discharging device on the bottom of the reactor respectively. The
method is economic, environment-protective, safe, low-costly. The regenerated
alumina will not poison palladium catalyst.
