Systems and methods for using and regenerating a catalyst for producing acetic acid from ethane are disclosed. Feed stream comprising ethane and an oxidant including oxygen is flowed to a reactor, in which a catalyst comprising MoVNbPd oxide is disposed. The ethane and the oxidant are reacted in presence of the catalyst under reaction conditions sufficient to produce acetic acid. When the catalyst's ability to catalyze the reaction between the ethane and the oxidant is reduced by a predetermined percentage, the flow of the feed stream to the reactor is ceased. A regenerating gas stream is flowed through the reactor to contact the regenerating gas stream with the catalyst under operating conditions to increase the catalyst's ability to catalyze the reaction between the ethane and the oxidant.

Method of reactivating catalyst

Disclosed are heterostructured silica catalysts (modified Haider heterostructured silica) and methods of their use and preparation.
