Abstract
A process has been discovered for the conversion of C.sub.5 -C.sub.7 olefinic hydrocarbons, such as those contained in FCC light naphtha, to iso-butene-rich and isoamylene-rich streams in an integrated process for the production of MTBE and TAME. The process involves the initial separation of the isoamylene-rich C.sub.5 -fraction of the feedstream which is converted to TAME. The C.sub.6 -C.sub.7 fraction plus unreacted C.sub.5 's are converted by olefin interconversion with medium pore zeolite catalyst into an isobutylene and isoamylene-rich stream which is then used as feedstream for etherification to MTBE and TAME.
