A METHOD FOR PRODUCING OLEFINS AND/OR ETHERS OF HIGH OCTANE NUMBER

摘要

A wide olefinic C2 to C10 stream is restructured over a special zeolite catalyst to form primarily C4 to C7 olefins, the C4 to C7 isoolefins are reacted with methanol over an acid catalyst to form high octane ethers, and unreacted olefins and methanol separated from the ether product are recycled to the olefin restructuring operation.
