Patent number: 7759288Abstract: Base treated aluminas exhibit improved CO2 capacity over untreated aluminas. Base treated aluminas prepared by physically mixing alumina and base during forming have (1) a higher surface area, (2) less hydrothermal aging, (3) improved CO2 capacity and (4) lower cost than base treated aluminas produced by aqueous impregnation. A method for removing at least CO2 and water from a gas stream includes providing an adsorbent formed from a process comprising physically mixing activated alumina solids and solid salts of alkali metals, alkaline earth metals or ammonium ion; and contacting the gas stream with the adsorbent.Type: GrantFiled: July 27, 2005Date of Patent: July 20, 2010Assignee: Air Products and Chemicals, Inc.Inventors: Derek Alan Prichett, Roy Adolph Meikle, Timothy Christopher Golden, Mohammad Ali Kalbassi, Fred William Taylor, Christopher James Raiswell, Jon Louis Mogan

Patent number: 5917136Abstract: A pressure swing adsorption process for absorbing CO.sub.2 from a gaseous mixture containing CO.sub.2 comprising introducing the gaseous mixture at a first pressure into a reactor containing a modified alumina adsorbent maintained at a temperature ranging from 100.degree. C. and 500.degree.

The modified alumina adsorbent which is formed by depositing a solution having a pH of 3.0 or more onto alumina and heating the alumina to a temperature ranging from 100.degree. C. and 600.degree. C., is not degraded by high concentrations of water under process operating conditions.Type: GrantFiled: October 3, 1996Date of Patent: June 29, 1999Assignee: Air Products and Chemicals, Inc.Inventors: Thomas Richard Gaffney, Timothy Christopher Golden, Steven Gerard Mayorga, Jeffrey Richard Brzozowski, Fred William Taylor
