ABSTRACT:
In a combination alkylation-methyltertiary butyl ether (MTBE) operation, the unreacted C.sub.4 olefinic hydrocarbons produced by etherification are contacted with molecular sieves to absorb 2-butenes and the 1-butenes remaining in the stream are divided so that one portion is subjected to double bond isomerization to form 2-butenes for alkylation and another portion is subjected skeletal isomerization to form isobutene for etherification.
