  • Recovery of acetophenone during the production of phenol
    Patent number: 8530702
    Abstract: A method for producing acetophenone comprising: treating one or more alkylbenzenes comprising s-butylbenzene to produce a feed comprising phenol and acetophenone; separating a crude phenol stream from the feed under crude phenol separation conditions effective to produce a crude phenol heavies; and, separating an acetophenone stream directly from the crude phenol heavies under azeotropic distillation conditions.
    Type: Grant

    Date of Patent: September 10, 2013
    Assignee: Shell Oil Company
    Inventors: Jesse Raymond Black, Larry Wayne Payne, Phillip Edward Unger

  • Process for making a linear alpha-olefin oligomer using a heat exchanger
    Publication number: 20040122269
    Abstract: The invention pertains to a process for making a linear alpha-olefin oligomer in a reactor comprising a liquid and a gas phase, comprising the steps of catalytically oligomerizing ethylene in the presence of an iron complex of a 2,6-bis(arylimino)pyridine derivative, to an alpha-olefin oligomer under release of heat, and removing the heat with a heat exchanger, which is not in direct contact with the liquid phase, using at least part of the gas phase as a coolant medium. The invention further relates to an apparatus to perform said process.

  • Process for making a linear alpha-olefin oligomer using a heat exchanger
    Publication number: 20040122271
    Abstract: The invention pertains to a process for making a linear alpha-olefin oligomer in a reactor comprising a liquid and a gas phase, comprising the steps of catalytically oligomerizing ethylene in the presence of a nickel, palladium, cobalt, titanium, zirconium, hafnium, vanadium, chromium, molybdenum or tungsten complex, to an alpha-olefin oligomer which preferably has an average molecular weight between 50 and 350 under release of heat, and removing the heat with a heat exchanger, which is not in direct contact with the liquid phase, using at least part of the gas phase as a coolant medium. The invention further relate to an apparatus to perform said process.
