  • Alumina having bimodal pore structure, catalysts made therefrom and processes using same
    Patent number: 6984310
    Abstract: Alumina having a pore structure characterized by the absence of macropores, no more than 5% of the total pore volume in pores greater than 350 ?, a high pore volume (greater than 0.8 cc/g measured by mercury intrusion) and a bi-modal pore volume distribution character, where the two modes are separated by 10 to 200 ?, and the primary pore mode is larger than the median pore diameter (MPD), calculated either by volume or by surface area, the MPD by volume being itself larger than the MPD by surface area. Also provided are catalysts made from and processes using such alumina.
    Type: Grant
    Filed: December 17, 2002
    Date of Patent: January 10, 2006
    Assignee: Shell Oil Company

  • Method of making alumina having bimodal pore structure, and catalysts made therefrom
    Patent number: 6589908
    Abstract: A method for making alumina having a pore structure characterized by the absence of macropores, no more than 5% of the total pore volume in pores greater than 350 Å, a high pore volume (greater than 0.8 cc/g measured by mercury intrusion) and a bi-modal pore volume distribution character, where the two modes are separated by 10 to 200 Å, and the primary pore mode is larger than the median pore diameter (MPD), calculated either by volume or by surface area, the MPD by volume being itself larger than the MPD by surface area. Alumina made by such process and catalyst made therefrom.
