Abstract
Embodiments described herein generally relate to apparatus and methods for reducing CO2 from flue gas. Methods may include performing a chemisorption process in a first reactor comprising using at least a chemisorption solution comprising a sorbent. Methods may also include performing a desorption process treating the chemisorption solution with a powdered desorption catalyst after the chemisorption process has been performed.
Claims20
A method of reducing CO2 from flue gas, comprising:
- performing a chemisorption process in a first reactor comprising using at least a chemisorption solution comprising a sorbent;
- and
- performing a desorption process by treating the chemisorption solution with a powdered desorption catalyst after the chemisorption process is performed.
A method of reducing CO2 from flue gas, comprising:
- performing a chemisorption process in a first reactor comprising using at least a chemisorption solution comprising a sorbent, wherein the chemisorption process is performed at ambient temperature;
- and
- performing a desorption process in a second reactor by treating the chemisorption solution with a powdered desorption catalyst, wherein the desorption process is performed at a temperature from about 35° C. to about 75° C.
An apparatus for performing chemisorption and desorption processes comprising:
- a chemisorption reactor configured to perform a chemisorption process;
- a first conduit coupled with the chemisorption reactor at a first end and a desorption reactor at a second end, wherein the first conduit is configured to transport CO2-rich sorbent to the desorption reactor, wherein the desorption reactor is configured to perform a desorption process;
- a reflux condenser coupled with the desorption reactor at a first end;
- a second conduit coupled with the desorption reactor at a first end and the chemisorption reactor at a second end, wherein the second conduit is configured to transport regenerated sorbent to the chemisorption reactor;
- and
- a controller configured to control the apparatus for performing the chemisorption process in the chemisorption reactor and the desorption process in the desorption reactor, wherein the chemisorption process comprises using at least a chemisorption solution comprising a sorbent, and wherein the desorption process comprises treating the chemisorption solution with a powdered desorption catalyst after the chemisorption process is performed.
