ABSTRACT:
A process for production of ether by 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 olefin 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 to control temperature of hot effluent from a preceding reaction zone.
