PRESENT STATUS AND DEVELOPMENT OF TECHNOLOGY FOR REMOVING OLEFINS FROM REFORMATE

The present status and developing trend of processes and catalysts for removing olefins from reformate were introduced focusing on the evolvement of the processes and R & D of the catalysts in a few large petrochemical corporations worldwide.The distributions of olefins in reformate and factors affecting the formation of olefins were discussed.It was found that C6 and C7 olefins were the main olefins in reformate,and their contents increased with the reaction severity.Finally,suggestions for domestic research thinking in these aspects were proposed,such as developing catalyst having high activity and stability,can be regenerated for times to replace clay treatment substantially and so on.
