Abstract
Shaped porous bodies of alpha-alumina platelets which are useful as catalyst carriers, filters, membrane reactors, and preformed bodies for composites are disclosed. Processes for modifying the surface composition of alpha-alumina are also disclosed. The processes involve contacting with fluorine-containing gas. Such modified alpha-alumina may be used as catalyst carrier for epoxidation reactions.
