A Grand Canonical Monte-Carlo Simulation of the textural, Mechanical and Adsorption Properties of Faujasite zeolite carbon replica
نویسندگان
چکیده
In this work, we present a Grand Canonical Monte-Carlo simulation results for the adsorption of carbon vapour in the pores of faujasite zeolite (in its siliceous form). The carboncarbon interactions are described within the frame of a Tight Binding approach (fourth momentum’s method) while the carbon-zeolite interactions are modelled using a PN-TrAZ physisorption potential. Siliceous faujasite allows obtaining a 3D connected porous material. The intrinsic stability of such carbon nanostructures was also investigated after removal of the inorganic phase, for there mechanical properties, and there gas adsorption properties. We also have shown that the replica hydrostatic mechanical properties are much better compared to the zeolite and with a very low density. The comparison of the calculated structure factor with experimental studies has given a criterium to characterize the perfect replica. Therefore, we calculated the pore size distribution (PSD) offering to experiments a precision more.

متن کاملAdsorption of Water on Sodium Faujasite by Grand Canonical Monte Carlo Simulations
Faujasitic zeolites are employed in a range of industrial contexts including separation processes, gas purification and dehydration, and shape selective catalysis. The simulation of the interaction of small molecules with faujasite based zeolites is increasingly practical and the resulting information provides the basis for efficient materials selection and design. When experimental data are sc...

The adsorption and separation properties of 3A zeolite are investigated by using Grand Canonical Monte Carlo (GCMC) simulation. To obtain the adsorption isotherms of water, methyl mercaptan, and methane on 3A zeolite, COMPASS Force Filed is used. The adsorption isotherms of the pure components and the ternary mixtures of water, methyl mercaptan, and methane on 3A zeolites are calculated. The Si...
متن کامل2007: A GRAND CANONICAL MONTE-CARLO STUDY OF H2 ADSORPTION IN PRISTINE AND Li-DOPED CARBON REPLICAS OF FAUJASITE ZEOLITE
The first step of this work was to generate using atomistic simulation, a porous carbon material with an ordered pore network using the faujasite Y zeolite as a templating matrix. For this purpose, we used the Grand Canonical Monte-Carlo (GCMC) technique in which the carbon-carbon interactions were described with reactive bond-order potential assuming the carbonzeolite interactions to be releva...
