Abstract
In an etherification process that uses an FCC effluent as a source of isoolefins, the buildup of nitriles in an alcohol-containing stream that is recycled to the etherification zone is prevented by dragging at least a portion of the methanol-containing stream to the FCC reaction zone. As a result, the etherification catalyst deactivation rate is reduced.
