Refinery oxygenate production can be increased using C[sub 5] to C[sub 7] olefins from FCC gasoline. The mandated changes in gasoline formulation and process technology innovations make this option attractive. New technology allows use of heavier olefinic feeds and avoids processing problems due to high diolefines concentration. Gasoline reformulation entails limits on volatile organic compounds (VOCs) and reactive olefins, and specifies minimum oxygen content. Removing olefins by etherifying them serves all of these objectives. A better understanding of technology for processing light gasolines into oxygenates involves: knowing olefin characteristic expected in FCC gasoline and analyzing pilot plant data on direct etherification of light FCC gasolines. This paper describes reactivity and vapor pressure of feeds and products; etherifying C[sub 5] to C[sub 7] branched olefins; reactive olefins in FCC gasolines; removal of gum precursors; yield of reactive olefins from hydrogenation; ether yields; and skeletal isomerization which reduces reactive linear olefins.
