  • Inhibiting popcorn polymer formation with sulfur-containing compounds
    Patent number: 5345030
    Abstract: Inhibition of popcorn polymer growth by treatment with a sulfur-containing compound. The sulfur-containing compound can be added to organic material from which popcorn polymer is formed, or applied to extant popcorn polymer.
    Type: Grant
    Filed: March 11, 1993
    Date of Patent: September 6, 1994
    Assignee: Exxon Chemical Patents Inc.
    Inventors: Hsiang-ning Sun, John J. Cikut, Roque V. Martir, Jos P. Wristers

  • Minimizing deactivation of ether synthesis catalyst
    Patent number: 5118871
    Abstract: A method for producing alkyl tertiary alkyl ether involves supplying a feed including isoolefins, alcohols, and dialkyl sulfides into a feed zone of a reactor; contacting the feed with a catalyst material in the reaction zone; and catalytically reacting the isooolefins and alcohols under conditions which favor forming resultant ether and inhibiting reaction of dialkyl sulfides with the catalyst material.
    Type: Grant
    Filed: January 24, 1991
    Date of Patent: June 2, 1992
    Assignee: Exxon Chemical Patents Inc

  • Multi-stage gas liquid reactor
    Patent number: 4329234
    Abstract: A multi-stage gas/liquid reactor is disclosed which has several concentric internal baffles, which define reaction stage zones. A central liquid inlet and an array of gas inlets supply the reactants which flow sequentially through diametrically opposed baffle passages to the various reaction stage zones. A method of using such a reactor to provide radially outward, positive pressure against the baffles is also disclosed.
