CO2 Transfer Across a Liquid Membrane Facilitated by Carbonic Anhydrase
Increasing atmospheric levels of CO2, in large part due to anthropogenic combustion of energy yielding hydrocarbons, portends significant if not catastrophic weather related events. One strategy to stabilize atmospheric CO2 levels is to capture the post-combustion product for disposal or, preferably, commercial use. The latter case, in particular, requires the development of both effective and ...
متن کاملMass Transfer Modeling of CO2 Absorption into Blended MDEA-MEA Solution
In this research, the thermodynamics and mass transfer of CO2 absorption has been studied in a mixture of MDEA-MEA amines. A relation is presented for mass transfer flux in the reactive-absorption process. For this purpose, the effective parameters on the mass transfer flux were investigated in both liquid and gas phases. Then, using dimensional analysis with the Pi-Buckingham theorem, the effe...
متن کاملCarbonic anhydrase mimics for enhanced CO2 absorption in an amine-based capture solvent.
Two new small-molecule enzyme mimics of carbonic anhydrase were prepared and characterized. These complexes contain the salen-like ligand bis(hydroxyphenyl)phenanthroline. This ligand is similar to the salen-type ligands previously incorporated into carbonic anhydrase mimics but contains no hydrolyzable imine groups and therefore serves as a promising ligand scaffold for the synthesis of a more...

متن کاملCarbonic anhydrase immobilized on encapsulated magnetic nanoparticles for CO2 sequestration.
Bovine carbonic anhydrase (BCA) was covalently immobilized onto OAPS (octa(aminophenyl)silsesquioxane)-functionalized Fe(3)O(4)/SiO(2) nanoparticles by using glutaraldehyde as a spacer. The Fe(3)O(4) nanoparticles were coated with SiO(2), onto which was grafted OAPS, and the product was characterized using SEM, TEM, XRD, IR, X-ray photoelectron spectroscopy (XPS), and magnetometer analysis. The...
