Abstract: The etherification of FCC light gasoline is an ideal process to reduce olefin content in gasoline and with minimum octane loss, but trace amount of nitrogen compounds in the gasoline may lead deactivation of etherification catalyst, so these nitrogen compounds should be removed. In this paper, methods for removing nitrogen compounds in FCC light gasoline, such as extraction, adsorption, pre-hydrogenation and etc. are summarized including the benefits and limitations of each process and new progresses in denitrogenation technology. The future developing trend of removing nitrogen compounds in FCC light gasoline is also discussed.

Key words: gasoline, nitrogen compound removal, extraction, adsorption, pre-hydrogenation
