New expressions for single and binary permeation through zeolite membranes for different isotherm models

Investigating the potential of MgMOF-74 membranes for CO2 capture

“…5c, and in the extensive MD simulation results for MFI presented earlier [40,55], Ð i /Ð ii for guest molecules such as CO 2 , and linear alkanes in MFI increases significantly with pore concentration. The permeIsosteric he at of adso rpt ion, -ΔH st / kJ mol ation calculations of Lito et al [56] must therefore be viewed with caution. Indeed, an important message that emerges later in this paper is that the increase in the degree of correlations with pore concentrations is a key to the success of MgMOF-74 membrane separations.…”

“…Subsequently, MD simulation results became available to show the Ð i /Ð ii varies with pore concentrations for all guest-host combinations [40,55]. It is remarkable, therefore, to note that the recent paper by Lito et al [56] invokes the assumption Ð i /Ð ii = 1 to describe diffusion across both MFI membranes. As seen from the data in Fig.…”

Experimental and Neural Network Modeling of Partial Uptake for a Carbon Dioxide/Methane/Water Ternary Mixture on 13X Zeolite

“…Thel ack of the analysis of binary and ternary mixtures as individualc omponents and their compositions had been an issue for some time.I n2 000, Heslope tal. [67] tried to find the absolute compositiono fb inary gas mixtures by adding mixtures of known components.L ito et al [68] studied new models that might predictbinary mixtures from pure adsorption data on zeolite membranes. Mulgundmath et al [69] studied the removal of CO 2 from N 2 in ab reakthrough for the behavior modelingo fh eat and mass transfer.…”

Modelling gas permeation through new microporous titanosilicate AM-3 membranes

“…Nonetheless, the hopping model is the most frequently adopted for modelling surface diffusion in micropores [9,13,[16][17][18][19][20][21][22], being adopted as well in this paper.…”
