Balanced alkylation feed from etherification and isomerization

摘要

An etherification process combines an alkylation zone with a skeletal olefin isomerization zone in an arrangement that rejects isoalkanes and normal alkanes with only minor loss of valuable olefin isomers. The invention also provides a balanced feed to an alkylation zone for the production of high octane gasoline components. This invention can be used to provide ethers and gasoline boiling range alkylates from either C4 or C5 feedstocks. The invention fully utilizes all olefin isomers improve octane and vapor pressure charactristics of the gasoline components.
