    • 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.
    • 通过在含有多孔固体金属氧化物的酸性烯烃水合和醚化催化剂的多个催化反应区中,在烯烃水合和醚化条件下使烯属原料与水接触来水解和醚化含有至少一种低级烯烃的烯烃原料来生产乙醚的方法 。 通过从至少一个固定床水合区回收第一流出物流,将第一流出物流分解成产物回收物流和多个再循环物流,以及使包含烯烃,醇的至少一部分冷却的循环物流 和乙醚以流出物流组分比例用于淬灭至少一个固定床反应区以控制来自前一反应区的热流出物的温度。
