  • Olefin hydration process
    Patent number: 9266801
    Abstract: The invention is directed to improvements in the indirect hydration process for the production of alcohols that enable high alcohol yield by increasing ether recycle in an olefin hydration process, such as the hydration process to produce isopropyl alcohol (IPA) from propylene or the hydration process to produce sec-butyl alcohol (SBA) from butylene.
    Type: Grant
    Filed: June 17, 2010
    Date of Patent: February 23, 2016
    Assignee: ExxonMobil Chemical Patents Inc.

  • Process for alcohol production by selective ether decomposition
    Patent number: 7399891
    Abstract: 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.
