  • Turbulent flow reactor
    Patent number: 5334357
    Abstract: A process for turbulently flowing together reactants in uniform proportions in a reactor vessel. A process for producing ethylbenzene by reacting ethylene and benzene in the presence of a catalyst in a reactor vessel from which useful heat generated by the reaction is transferred to a heat transfer medium flowing through the reactor and in which the reaction occurs in a relatively short time period. In one embodiment, polyethylbenzenes produced in the reactor vessel are not recycled into the vessel. A reactor for a reaction of reactant materials that are uniformly and turbulently mixed together.
    Type: Grant
    Filed: December 17, 1992
    Date of Patent: August 2, 1994
    Assignee: The Dow Chemical Company
    Inventors: James H. Benton, Jack Broodo, John B. Ivy, Kirk A. Leissner, Ellroy G. Fox
