A graphical method, based on a set of acid-base titrations, is
presented for the determination of the carbon dioxide speciation in
natural solutions. The application of this method, in conjunction
with measurements of the partial pressure of carbon dioxide with
which our solutions were in equilibrium permitted the calculation
of...
The ratio of the absolute infrared intensity, A₃/A₂, for the
parallel mode (2336 cm⁻¹) and the perpendicular mode (658 cm⁻¹)
of a nonpolar solute molecule, carbon dioxide, has been determined
in a nonpolar solvent, Nujol. The solution ratio (5.0) which has
been extrapolated to zero concentration is less than the...
A cascade crosscurrent column, packed with Pall rings, was
employed for carbon dioxide absorption from a carbon dioxide-rich
air phase by contacting with water. Absorption efficiency was
presented as the percentage of CO₂ removed versus gas flow rates for
constant liquid to gas ratios (L/G).
Curves were developed for an...
The carbon is photoelectron spectrum of CO₂ has been measured with very high photon energy resolution. The natural lifetime of the carbon is hole state has been determined from a series of spectra taken at photon energies of 308, 320, and 330 eV. The measured values of the lifetimes show...
In the vicinity of the pseudocritical point, supercritical carbon dioxide (sCO₂) undergoes a steep change in properties from “liquid-like” to “gas-like” as it is heated at a constant pressure. At the same time, there is a large spike in specific heat which can yield high heat transfer coefficients and heat...
Global warming is becoming an increasingly important environmental concern and CO₂ is considered as the major cause of global warming. Creating useful applications for CO₂ would generate alternatives to merely venting CO₂ to the atmosphere, and decreasing the carbon intensity of human activities. Among various methods of CO₂ utilization, conversion...
