Binary Adsorption Equilibrium of Carbon Dioxide and Water Vapor on Zeolite HY
Introduction An understanding of how CO2 and H2O interact and affect each other’s behavior on adsorbent surfaces is essential for both theoretical study and industrial processes especially CO2 capture from wet flue gas streams. There are few reported studies on adsorption equilibrium for such a binary system. Rege and Yang [1] measured very low concentration of CO2/H2O vapor (<4.1% relative hum...
متن کاملMolecular simulation study of the competitive adsorption of H2O and CO2 in zeolite 13X.
The presence of H2O in postcombustion gas streams is an important technical issue for deploying CO2-selective adsorbents. Because of its permanent dipole, H2O can interact strongly with materials where the selectivity for CO2 is a consequence of its quadrupole interacting with charges in the material. We performed molecular simulations to model the adsorption of pure H2O and CO2 as well as H2O/...
متن کاملEffects of Water Content on SO2/N2 Binary Adsorption Capacities of 13X and 5A Molecular Sieve, Experiment, Simulation, and Modeling
In this work, SO2 adsorption on 13X and 5A was explored at different concentrations, and the results were compared to molecular simulation and models. The adsorbent saturation tests were performed at four different concentrations of 250, 500, 750, and 1000 ppm, and it was observed that saturation would take more time for higher SO2 concentrations. Grand Canonical Monte Carlo method was used for...
متن کاملMolecular dynamics simulation of a binary mixture lubricant for use in hard disk interfaces
In Hard Disk Drives (HDD), it is necessary to decrease the Flying Height (FH) between the head and the disk (currently, FH is around 3-5 nm) so as to increase recording densities. Retaining the solid lubricant has become a difficult proposition owing to intermittent contact between the surfaces. ZTMD and Z are used as solid lubricant to lubricate these interfaces. In this paper, the behavior of...
