  • Selective adsorption of alkenes using supported metal compounds
    Patent number: 6867166
    Abstract: The invention provides novel adsorbents for use in the separation of unsaturated hydrocarbons from a mixture of gases containing such hydrocarbons. The preferred adsorbents comprise metal compounds supported on high surface area carriers. The adsorbents of the invention are usable in pressure swing adsorption or temperature swing adsorption processes.
    Type: Grant
    Filed: February 25, 2002
    Date of Patent: March 15, 2005
    Assignee: The Regents of the University of Michigan
    Inventors: Ralph T. Yang, Joel Padin, Salil U. Rege

  • Process for purifying propylene
    Patent number: 6406521
    Abstract: A process is provided for the concentration and recovery of propylene from propane by a pressure swing adsorption (PSA) process using an adsorbent comprising AlPO-14. A PSA process is used to remove propylene from a C3 hydrocarbon stream comprising propylene and propane. The PSA process of the present invention can be employed in petroleum refining and petrochemical processes to purify and separate propylene from mixtures of propylene and propane without fractionation.
