    • This invention relates to a process for the production of an alcohol, the process comprising (a) reacting an olefin and water in the presence of a catalyst under conditions sufficient to form a crude alcohol stream comprising alcohol, and a dialkyl ether; (b) separating at least a portion of the crude alcohol stream into an alcohol-containing stream and a dialkyl ether stream; (c) contacting at least a portion of the dialkyl ether stream with an ether decomposition catalyst, the ether decomposition catalyst comprising a mixed metal oxide having the following composition XmYnZpOq where X is at least one metal selected from Group 4 of the Periodic Table of Elements, Y is at least one metal selected from Group 3 (including the Lanthanides and Actinides) and Group 6 of the Periodic Table of Elements and Z is at least one metal selected from Groups 7, 8, and 11 of the Periodic Table of Elements; m, n, p, and q are the atomic ratios of their respective components and, when m is 1, n is from about 0.01 to about 0.75, p is from 0 to about 0.1, and q is the number of oxygen atoms necessary to satisfy the valence of the other components, to form a crude dialkyl ether decomposition stream comprising alcohol and olefin; (d) recovering at least a portion of the olefin from the crude dialkyl ether decomposition stream; and (e) recycling at least a portion of the olefin recovered in step (d) to step (a).
    • 本发明涉及一种生产醇的方法,该方法包括(a)在足以形成包含醇和二烷基醚的粗醇物流的条件下,在催化剂存在下使烯烃和水反应; (b)将至少一部分粗醇流分离成含醇流和二烷基醚流; (c)使至少一部分二烷基醚料流与醚分解催化剂接触,所述醚分解催化剂包含具有以下组成的混合金属氧化物: 其中X是选自元素周期表第4族的至少一种金属,Y是选自第3族(包括镧系元素)中的至少一种金属 和锕系元素)和元素周期表第6族,Z是选自元素周期表第7,8和11族中的至少一种金属; m,n,p和q是它们各自成分的原子比,当m为1时,n为约0.01至约0.75,p为0至约0.1,q为必需的氧原子数 满足其他组分的化合价,形成包含醇和烯烃的粗二烷基醚分解物流; (d)从粗二烷基醚分解流中回收至少一部分烯烃; 和(e)将步骤(d)中回收的烯烃的至少一部分再循环到步骤(a)。
