  • Oligomerisation of olefins
    Patent number: 8598396
    Abstract: Olefin feeds with high olefin content and/or containing a substance that generates water when contacting the catalyst, are oligomerised over solid phosphoric acid catalyst in tubular reactors by introducing the olefin feed into the reactor and maintaining the reacting mixture under conditions whereby the peak temperature is controlled to be below 265° C. and preferably a single liquid or dense phase is maintained and the average temperature throughout the reactor is maintained in the range 190° C. to 260° C.
    Type: Grant
    Filed: June 9, 2006
    Date of Patent: December 3, 2013
    Assignee: ExxonMobil Chemical Patents Inc.
    Inventors: Stephen Wayne Beadle, John Stephen Godsmark, Robert L. Wolf

  • Hydroformylation
    Patent number: 7405329
    Abstract: The gas cycle in a high pressure hydroformylation reaction using a series of at least two reactors is controlled to optimise yield, conversion and selectivity and to control reaction temperature. The control is achieved through balancing fresh gases and recycle gases in each of the reactors and as an optional feature the use of hydrogen off gases from the downstream hydrogenation used in the conversion of the hydroformylation reaction product to product alcohols.
