ABSTRACT:
A process is disclosed for converting a light hydrocarbon feedstock that contains a mixture of linear and branched olefins to ether-rich high octane gasoline streams that include tertiary alkyl and isoalkyl ethers such as MTBE, TAME, methyl isopropyl ether (MIPE), and methyl sec-butylether (MSBE). The conversion is achieved by utilizing the differing reactivity of tertiary olefins under selected conditions compared to linear olefins in the catalyzed etherification processes. The discovery has been made that unreacted olefins from the etherification reactions can be converted to gasoline boiling range hydrocarbons by contacting them with zeolite catalyst at elevated temperature. Further, it has been discovered that unreacted paraffins in the integrated process can be dehydrogenated to produce C.sub.3 -C.sub.4 olefins which can be recycled to the etherification process.
