Abstract
Catalyst activity life of an iron oxide-containing catalyst is extended by contacting such catalyst with a feedstream containing about 0.0001 to about 0.01 mole of oxygen per mole of feed in the substantial absence of an oxidation catalyst.
Claims2
A conversion process wherein an alkylaromatic compound is dealkylated using an iron oxide-containing catalyst contacting such catalyst with a feed containing about 0.0001 to about 0.01 mole of oxygen per mole of feed in the substantial absence of an oxidation catalyst whereby the life of said iron oxide-containing catalyst is extended.
