Abstract:
1. A method of separating CO 2 from a process gas stream comprised of CO 2 and other gaseous constituents in an adsorption/desorption cycle using a zeolite sorbent, where the desorption cycle is conducted under conditions of increased temperature and increased CO 2 pressure to produce a high pressure output gas stream, comprising: Generating an input gas stream comprised of the process gas stream, such that the input gas stream is comprised of CO Contacting the input gas stream with the zeolite sorbent at a first temperature and the first CO Surrounding the loaded zeolite sorbent with a CO Generating the output gas stream, where the output gas stream is comprised of some portion of the CO thereby separating CO 2 from a process gas stream comprised of CO 2 and other gaseous constituents in an adsorption/desorption cycle using a zeolite sorbent, where the desorption cycle is conducted under conditions of increased temperature and increased CO 2 pressure to produce a high pressure output gas stream.
