1. A combination process is described for producing high octane blending components for gasolines which consists of (a) contacting a mixture of methanol and an olefinic C/sub 4/ cut comprising isobutene, 1-butene, and 2-butenes under etherification conditions to produce methyltertiarybutyl ether and unreacted C/sub 4/ olefinic hydrocarbons, (b) contacting the unreacted C/sub 4/ olefinic hydrocarbons with a molecular sieve to selectively adsorb 2-butenes leaving a stream comprising 1-butene, (c) subjecting at least a portion of the 1-butene stream to skeletal isomerization to form isobutene, (d) subjecting the remainder of the 1-butene stream to double bond isomerization to form 2-butenes, and (e) passing the 2-butenes formed by isomerization and an isoparaffin to alkylation to form alkylate.
