Appl. No.:

15/875471

Inventors:

- Houston TX, US
Jason Ho - Houston TX, US

Assignee:

William Marsh Rice University - Houston TX

Abstract:

The present disclosure pertains to methods of capturing COfrom an environment at pressures above 1 bar by associating the environment with a porous material that has a surface area of at least 2,800 m/g, and a total pore volume of at least 1.35 cm/g, where a majority of pores of the porous material have diameters of less than 2 nm. The present disclosure also pertains to methods for the separation of COfrom natural gas in an environment at partial pressures of either component above 1 bar by associating the environment with a porous material that has a surface area of at least 2,200 m/g, and a total pore volume of at least 1.00 cm/g, where a majority of pores of the porous material have diameters of greater than 1 nm and less than 2 nm.

Abstract:

The present disclosure pertains to materials for COadsorption at pressures above 1 bar, where the materials include a porous material with a surface area of at least 2,800 m/g, and a total pore volume of at least 1.35 cm/g, where a majority of pores of the porous material have diameters of less than 2 nm as measured from Nsorption isotherms using the BET (Brunauer-Emmett-Teller) method. The present disclosure also pertains to materials for separation of COfrom natural gas at partial pressures of either component above 1 bar, where the materials include a porous material with a surface area of at least 2,200 m/g, and a total pore volume of at least 1.00 cm/g, where a majority of pores of the porous material have diameters of greater than 1 nm and less than 2 nm as measured from Nsorption isotherms using the BET method.

Abstract:

The present disclosure pertains to materials for COadsorption at pressures above 1 bar, where the materials include a porous carbon material with a surface area of at least 2800 m/g, a total pore volume of at least 1.35 cm/g, and a carbon content of 80%-95%. The porous carbon material is prepared by heating organic polymer precursors or biological materials in the presence of KOH at 700 C.-800 C. The present disclosure also pertains to materials for the separation of COfrom natural gas at partial pressures above 1 bar, where the material includes a porous carbon material with a surface area of at least 2000 m/g, a total pore volume of at least 1.00 cm/g, and a carbon content of greater than 90%. The porous carbon materials can be prepared by heating organic polymer precursors or biological materials in the presence of KOH at 600 C.-700 C.

Assignee:

Apache Corporation - Houston TX

International Classification:

B01D 53/047

Abstract:

A pressure swing adsorption (PSA) system and a PSA process including a PSA cycle schedule are disclosed. The PSA cycle schedule includes an unlimited number of equalization steps, no idle steps, no dead time and a minimum number of three PSA adsorbent beds assisted with two or more equalization tanks. The PSA system, process and cycle schedule include the following sequence of cycle steps: a feed step, two or more down equalization steps either between beds or between a bed and a tank, an optional forced cocurrent depressurization step coupled with a forced intermediary light end pressurization step, a countercurrent depressurization step, a light reflux step, two or more up equalization steps between beds or between a bed and a tank, an optional forced intermediary light end pressurization step coupled with the forced cocurrent depressurization step, and a light product pressurization step.
