F-5819 ABSTRACT REACTOR QUENCHING FOR CATALYTIC OLEFIN HYDRATION IN ETHER PRODUCTION A process for production of ether by catalytic hydration and etherification of olefinic feedstock containing at least one lower alkene by contacting the olefinic feedstock and water in a plurality of catalytic reaction zones containing porous solid metal oxide acidic olefin hydration and etherification catalyst under hydration and etherification conditions. Improved operation is achieved by recovering a first effluent stream from at least one fixed bed hydration zone; splitting the first effluent stream into a product recovery stream and a plurality of recycle streams; and passing at least a portion of cooled recycle streams comprising olefin, alcohol and ether in effluent stream component proportions for quenching at least one fixed bed reaction zone along with hot effluent from a preceding reaction zone.
