Methods and systems for CO2 separation

Title: Methods and systems for CO2 separation

Abstract

A method for separating carbon dioxide (CO2) from a gas stream is provided. The method includes reacting at least a portion of CO2 in the gas stream with a plurality of liquid sorbent particles to form a plurality of solid adduct particles and a first CO2-lean gas stream; the solid adduct particles entrained in the first CO2-lean gas stream to form an entrained gas stream. The method includes separating at least a portion of the plurality of solid adduct particles from the entrained gas stream in a separation unit to form an adduct stream and a second CO2-lean gas stream. The method further includes heating at least a portion of the adduct stream in a desorption unit to form a CO2 stream and a regenerated liquid sorbent stream. A system for separating CO2 from a gas stream is also provided.

Simulated moving bed system for CO2 separation, and method of same

Patent Elliott, Jeannine Elizabeth; Copeland, Robert James; Lind, Jeff; ...

A system and method for separating and/or purification of CO2 gas from a CO2 feed stream is described. The system and method include a plurality of fixed sorbent beds, adsorption zones and desorption zones, where the sorbent beds are connected via valve and lines to create a simulated moving bed system, where the sorbent beds move from one adsorption position to another adsorption position, and then into one regeneration position to another regeneration position, and optionally back to an adsorption position. The system and method operate by concentration swing adsorption/desorption and by adsorptive/desorptive displacement.

Constructs and systems and methods for engineering a CO2 fixing photorespiratory by-pass pathway

Patent Kerfeld, Cheryl A.; Shih, Patrick; Zarzycki, Jan; ...

Methods and compositions to introduce a synthetic pathway based on the 3-hydroxypropionate bicycle into an organism such as the model cyanobacterium, Synechococcus elongatus sp. PCC 7942. The heterologously expressed pathway acts as a photorespiratory bypass as well as an additional carbon fixation cycle orthogonal to the endogenous Calvin-Benson cycle. We demonstrate the function of all six introduced enzymes, which not only has implications on increasing net-photosynthetic productivity, but also key enzymes in the pathway are involved in high-value products that are of biotechnological interest, such as 3-hydroxypropionate.
