  • CATALYST AND PROCESS USING THE CATALYST
    Publication number: 20070184973
    Abstract: A catalyst which comprises a carrier and silver deposited on the carrier, which carrier has a surface area of at least 1 m2/g, and a pore size distribution such that pores with diameters in the range of from 0.2 to 10 ?m represent at least 70% of the total pore volume and such pores together provide a pore volume of at least 0.
    Type: Application

    Applicant: Shell Oil Company
    Inventors: John LOCKEMEYER, Randall Yeates, Thomas Szymanski, Donald Remus, William Gerdes
  • Catalyst carrier and a process for preparing the catalyst carrier
    Publication number: 20060281631
    Abstract: A carrier, which comprises non-platelet alumina and/or a bond material, has a surface area of at least 1.3 m2/g, a total pore volume and a pore size distribution such that at least 80% of the total pore volume is contained in pores with diameters in the range of from 0.1 to 10 ?m, and at least 80% of the pore volume contained in the pores with diameters in the range of from 0.1 to 10 ?m is contained in pores with diameters in the range of from 0.

  • Catalyst carriers
    Publication number: 20050096219
    Abstract: The selectivity and activity of a silver-based olefin epoxidation catalyst is found to be a function of the pore size distribution in the alumina carrier on which it is deposited. Specifically it is found advantageous to provide a carrier which has a minimum of very large pores, (greater than 10 micrometers) and a water absorption of 35 to 55% and a surface area of at least 1.0 m2/g. A method of making such carriers is also described.
