  • Patent number: 10307733
    Abstract: The present disclosure relates to a material preferably used in a guard bed, and having an increased capacity to adsorb catalyst poisons, as measured by collidine update at 200° C. The material is made by a method in which it is treated by being dried with a drying gas, preferably, at a temperature greater than about 200° C. The treated material may be used to remove impurities from untreated feed streams to, for example, aromatic alkylation and transalkylation processes, where such impurities act as catalyst poisons that cause deactivation of the acidic molecular sieve-based catalysts used, thereby increasing the cycle length of such catalysts.
    Type: Grant
    Filed: November 11, 2015
    Date of Patent: June 4, 2019
    Assignee: ExxonMobil Chemical Patents Inc.
    Inventors: Matthew J. Vincent, Terry E. Helton, Jenna L. Walp, Dominick A. Zurlo, IV, Doug F. Colmyer
  • Patent number: 9919288
    Abstract: Adsorbent materials comprising a ZIF material and cross-linked polymer are provided herein. Methods of separating organic compounds from an aqueous solution or a non-aqueous solution and biofuel production processes using the adsorbent material are also provided herein.
    Type: Grant

  • Publication number: 20160168172
    Abstract: Organosilica materials, which are a polymer of at least one independent monomer of Formula [Z1OZ2SiCH2]3 (I), wherein each Z1 represents a hydrogen atom, a C1-C4 alkyl group or a bond to a silicon atom of another monomer and each Z2 represents a hydroxyl group, a C1-C4 alkoxy group, a C1-C6 alkyl group or an oxygen atom bonded to a silicon atom of another monomer and at least one other monomer are provided herein. Processes of using the organosilica materials, e.g., gas separation, etc., are also provided herein.
