Abstract
The present invention relates to methods for improving carbon capture using entrained catalytic-particles within an amine solvent. The particles are functionalized and appended with a CO2 hydration catalyst to enhance the kinetics of CO2 hydration and improve overall mass transfer of CO2 from an acid gas.
Claims20
A biphasic scrubbing solution comprising an amine solvent with catalyst-appended particles suspended therein, wherein the particles comprise a surface-appended carbon dioxide (CO2) adsorption catalyst and a particle, wherein the catalyst is appended to a surface of a particle through a particle linker and a catalyst linker, the catalyst linker being selected from:
- and
- further wherein the particles have a width of less than about 500 microns.
A biphasic scrubbing solution comprising an amine solvent with catalyst-appended particles suspended therein, wherein the catalyst-appended particles are selected from the group consisting of:
- or mixtures thereof, and further wherein
- represents the particle.
